Original Shanghai Xuhui Shanghai Xuhui

The gathering of relatives and friends and family reunion is the eternal theme of the Spring Festival. However, there are such a group of people who work hard day and night. During festivals, they still protect people’s lives and health with responsibility and provide quality medical services without interruption. They gave up the reunion with their families and gave up their small family for everyone. The busy figure of "angels in white" also became the warmest scenery in the festival.

In the process of condolences, Director Wang and the staff patiently listened to the stories of the veterans, and from time to time expressed their feelings and admiration. They sent condolences to the veterans, including food, health care products, daily necessities, etc., and specially prepared a red envelope for each veteran, hoping to give them some material and spiritual help.

In the Pediatrics Department of Shanghai Eighth People’s Hospital, there is still a 24-hour emergency during the Spring Festival. As usual, there are emergency medical care and ward medical care shifts every day to ensure that patients can see a doctor in time after arrival.

A child patient with vomiting and diarrhea came to see a doctor. The doctor initially diagnosed it as acute gastroenteritis in children, probably because he ate his stomach badly during the festival. "During the Spring Festival, if children eat more omnivores and don’t pay attention to hygiene, it will easily lead to acute gastroenteritis, manifested as vomiting and diarrhea, which may lead to dehydration in severe cases. If you have symptoms of poisoning or fever, you need to see a doctor in time. Therefore, during the Spring Festival, children’s diets need to be kept hygienic. " Lu Ding, director of pediatrics at Shanghai Eighth People’s Hospital, said.

It is reported that during the Spring Festival, there are two kinds of common children: cold and fever, acute gastroenteritis or indigestion. From the first day of the year to the third day of the year, the number of patients is relatively less than usual, and the arrangement of medical care is relatively reduced. At the same time, there are classes to be prepared, and it is not closed for 24 hours to deal with emergencies. I don’t rest at other times and go to work as usual.

On the New Year’s Eve, Lu Ding stuck to his post and prepared classes every day at other times. Asked if there was any regret in not being able to reunite with his family, she said: "Hospitals can’t close their doors and rest. There are always doctors who have to sit in the emergency room. This is our duty. Moreover, many colleagues in other places have not gone home for the Spring Festival for several years, so we need to ensure that they go home for reunion, so we must ensure the normal operation of the department in Shanghai. "

In the emergency department, it is also open 24 hours a day, and the allocation of medical staff is increased than usual. The patients who come to the emergency department during festivals are mainly patients who can’t wait, such as chest tightness, chest pain, abdominal pain and high fever, and most of them are elderly patients. A few days ago, a patient with chest pain was rushed to the emergency room of the emergency department. The nurse immediately completed the ECG and blood collection at the bedside and completed the examination within 20 minutes. Start DSA (Digital Subtraction Angiography) room immediately after determining myocardial infarction. Even during the holiday break, the relevant staff immediately rushed to the hospital to complete the coronary angiography and open the blocked blood vessels. The time from the patient entering the hospital gate to opening the blocked blood vessels in the heart is controlled within 90 minutes.

In ICU, the inpatients in the festival are basically full, and the doctors and nurses work in shifts to ensure 24-hour uninterrupted work, and all kinds of machines are also working normally. "Some critically ill patients with respiratory failure, heart failure and renal failure can’t leave the ventilator and can only stay in the ICU. Doctors will assess their condition every day and try to get them out of the machine one day earlier and go home for reunion one day earlier. " Zhou Xinjian, director of the Emergency Department and Department of Critical Care Medicine of Shanghai Eighth People’s Hospital, said, "I have been a doctor for more than 20 years, and many New Year’s Eve and festivals have been spent in hospitals and posts, which has become a routine. Since I chose this job, there is nothing to regret, and my family can understand my work. After all, serving the people is the belief of every medical staff. "

In the list of heroes in the War to Resist US Aggression and Aid Korea, there is a 21-year-old hero whose name has already spread all over China and North Korea with the Battle of Shangganling. He is Huang Jiguang who blocked the machine gun eye of the enemy bunker with his chest and was awarded the title of "Super Hero to Resist US Aggression and Aid Korea" by China and North Korea.

Huang Jiguang-based online movie "Superhero Huang Jiguang" is about to meet the audience. The film is a project supported by the State Administration of Radio and Television for the creation and dissemination of network audio-visual programs. It is directed by the Network Audio-visual Department of the State Administration of Radio and Television and the Beijing Radio and Television Bureau, supported by the 95944 troops of the China People’s Liberation Army and the Huang Jiguang Memorial Hall, and produced by Beijing Taomeng Network Technology Co., Ltd. The film tells the story of Huang Jiguang’s joining the army and growing up, as well as the story that he gave his life to block the loophole for the victory of the army. Huang Jiguang, the Superhero, won the first batch of Network Drama Distribution License issued by Beijing Radio and Television Bureau.

Find another way to find the entrance

Huang Jiguang was born in 1931 in a poor peasant family in Zhongjiang County, Sichuan Province. In March 1951, he actively responded to the call of "Resisting US Aggression and Aid Korea and Defending the Country", signed up for Chinese people’s Volunteer Army, and then crossed the Yalu River with the troops to fight in the DPRK. In the Battle of Shangganling, Huang Jiguang blocked the machine gun eyes strafed by the bunker with his chest, paving the way for the troops to charge and making a heroic sacrifice.

Many viewers are familiar with Huang Jiguang’s heroic deeds, but they are not familiar with his growth story. "Everyone has heard the story of Huang Jiguang blocking a loophole, but why did he block a loophole? What exactly did he do before plugging the loophole? In fact, many people don’t know it, and some people have questioned the authenticity of’ blocking gun holes’. " Zhou Runze, director of the film, said that as an online film with limited cost, Superhero Huang Jiguang wanted to stand out from the crowd not by grand war scenes, but by finding a new way to make its characters fuller and more grounded.

Yin Chao, the producer, founder and CEO of Amoy Dream, said that he didn’t want Huang Jiguang, the Superhero, to be made into a traditional biographical film, and he didn’t want this work to be over-commercialized or dramatized heroism, so he needed to find a suitable entrance. Through consulting a large number of historical materials, the creative team learned that Huang Jiguang, who was in his early teens, suffered the death of his father and was forced to work in the landlord’s house to pay his debts. His struggling mother told him that he must turn over for the poor when he grows up. "Although it’s a war theme, the team doesn’t want to over-magnify the war scenes, but instead, it grasps the small incision of’ the relationship between Huang Jiguang and his mother’ and shows how he grew from an ordinary soldier to a super hero through the growth environment. Of course, in addition to his mother, leaders, comrades-in-arms and fellow villagers also gave him great strength. "

Huang Jiguang, the Superhero, has made great efforts in plump characters. "Plump characters need a lot of life details to support them, and the team will also add some dramatic creations. However, dramatic creation should be based on real history. When sorting out the materials and materials, the team found that in fact, in Shangganling, there are many young people who have made selfless contributions to the country like Huang Jiguang. He is just the epitome of Qian Qian’s thousands of soldiers. " Yin Chao said that this film does not simply create a hero, but wants to restore a three-dimensional, real person, hoping to arouse the emotional resonance of the current young audience.

The war scene is strict with details.

Shooting war themes, characterization and war scenes need to be integrated. Zhou Runze said that "Superhero Huang Jiguang" is based on a true story, and it needs to restore the truth by heart, and "truth" is multifaceted. "Not only the plot should be true, the battlefield environment and the fighting process should be true, but also the time, place, props and guns involved in the war."

Zhou Runze introduced that when the previous script was not completed, the crew began to look for locations that met the requirements all over the country. "The conditions of the film and television base are very mature, but the natural environment is much different from the battlefield in Shangganling. When the team surveyed the landscape in the early stage, they went to Northeast China, Shandong and other places, and finally found that the shape and height of a mountainous area in Henan were suitable. "　

After choosing the shooting location, Zhou Runze, the military director and production designer ran back and forth on the mountain many times, and also let the actors experience it again and again with guns. "How to arrange the positions and trenches on the mountain? Where did Huang Jiguang fight from during the battle? Finally, where did the bunker where he wanted to block the loophole appear? Like the battle deduction, we went through the whole process and refined each battle process into the script. " Zhou Runze revealed that after the field experience and detailed planning, he couldn’t help crying while changing the script in the hotel at night. "After running on the mountain, I really realized how difficult it was for the volunteers to fight in the environment at that time."

In casting, in order to be closer to the characters, the team selected a group of newcomers as the leading actors, and invited professional military instructors to train the actors and carefully study various military actions. "There are veterans among the actors, and they thought their actions were very standard, but in fact, many military actions in the 1950s, including gun gestures, were different from those now, so no details can be relaxed."

Creating Heroes from "Humanity"

As a well-known enterprise in the online film industry, Taomeng has produced many military movies, including Bomber, Sniper and Life and Death Blocking. Now, when filming online movies with military themes again, Yin Chao hopes that "Superhero Huang Jiguang" can retain the audience with stories and characters, which not only needs to pave the way for the content, but also requires a more elaborate production process. "No matter what kind of carrier, the audience needs a good story. Huang Jiguang, the Superhero, has been carefully polished, and it has lasted for more than four years from planning to now, far exceeding the creation time of many online movies. We hope that in addition to entertainment, on the basis of the creation of’ Little Zhengda’, the audience can gain something and resonate. "

Zhou Runze said that the current theme creation, especially in shaping the heroes of revolutionary history, should put down the shelf with a correct attitude and proceed from human nature. "Blindly highlighting the image of the hero’ Gao Daquan’ has been difficult to be accepted by young audiences now. We need to calm down, look for the human side of heroes, and link the audience truly and naturally. Only in this way can the characteristics of heroes be highlighted. "

　　[Magnificent 70 Years, Struggle for a New Era]

　　Thirty years ago, a "green revolution" led by a warm vegetable greenhouse in winter was launched from Shouguang, Shandong Province, which solved the problem of single vegetable species in winter in northern China. Thirty years later, Shouguang’s greenhouse vegetable area has grown to 600,000 mu, with an annual output of 4.5 million tons of vegetables. In 2018, the per capita disposable income of rural residents in the city reached 20,627 yuan. The vegetable industry has enabled farmers to embark on the road of increasing income and getting rich.

　　Over the past 30 years, Shouguang has become a "vegetable basket" for the people of the whole country, and has developed a "six-in-one" modern agricultural industrialization "Shouguang Model" with market orientation, safety as the bottom line, science and technology as the driving force, brand as the guide, standardized production as the starting point and organized development as the path.

　　Increasing production turns to improving quality from growing vegetables to "planting technology"

　　Walking into the seventh-generation greenhouse displayed in Shouguang modern agricultural high-tech integration demonstration zone, the perfect integration of hanging tomato cultivation, rotating flower cultivation and modern fish pond makes people feel as if they are in a pure natural beauty. So, how to realize the "aquaponics" in a greenhouse?

　　"We regard the water in the fish pond as ‘ Nutrient solution ’ For vegetables, water ‘ Fertilizer ’ After being absorbed, it flows back to the fish pond, thus realizing the virtuous cycle symbiosis of fish and vegetables. " Wu Xuewen, project manager of Greer Agricultural Technology Co., Ltd., introduced that the greenhouse is also equipped with two-layer insulation system, automatic environmental control system, intelligent greenhouse control system and other facilities and equipment, so that crops are less affected by the external climate and provide an optimal growth environment for crops.

　　As a centralized display platform for new varieties, new technologies, new models, new equipment and new sales formats of Shouguang vegetables, the modern agricultural high-tech integrated demonstration zone has received more than 62,000 people to visit and study during the opening time of the park in the past year. From the first generation of winter-warm greenhouses to the seventh generation of greenhouses today, Shouguang has embarked on the development road from increasing production to improving quality from growing vegetables to "planting technology".

　　In 1989, Wang Leyi, secretary of the Party branch of Sanyuanzhu Village, Sunjiaji Street, Shouguang, invited Han Yongshan, a skilled person, from Wafangdian, Dalian, Liaoning Province, and led 16 other villagers to build a winter-warm vegetable greenhouse. A few months later, cucumbers in 17 greenhouses were robbed by high prices, and 17 "double-million households" appeared in Sanyuanzhu Village at once. In the second year, with the promotion of Wang Boxiang, then secretary of Shouguang County Party Committee, Shouguang built 5,130 greenhouses, and only one greenhouse vegetable production increased the county’s income by more than 60 million yuan.

　　Nowadays, many vegetable greenhouses in Sanyuanzhu Village have developed to the fifth and sixth generations, which are easy to operate, watering, ventilation and lighting can be controlled on the mobile phone, and they are full of intelligence. More importantly, vegetables are sold with labels. Scanning its "electronic identity" with a mobile phone can show farmers, fertilizers, planting conditions and other information.

　　"Every day, we transport the vegetables to the cooperative, and after sampling and inspection, we can post the QR code before loading them to all parts of the country. With the QR code traceability function, you can sell 2 cents more per catty of vegetables and earn more than 20,000 yuan a year on average, which not only allows everyone to eat safe dishes, but also increases our income. " Cong Wang, a villager from Sanyuanzhu Village, said.

　　In recent years, Sanyuan Zhucun has taken the road of high-quality development, and "Leyi" brand vegetables have not only enriched the domestic market, but also exported to European and American countries.

　　The development of the whole industrial chain realizes "buy the whole country and sell the whole country"

　　From two o’clock to five o’clock in the morning, when most people are still asleep, Shouguang Agricultural Products Logistics Park is a busy scene. Vehicles such as trucks, agricultural tricycles and small trucks come in and out from here, and the trading hall is crowded and lively.

　　"Most local farmers in Shouguang started picking vegetables in the middle of the night and sent them to the logistics park for trading at 2 am. Foreign dishes from Shanghai, Fujian and other provinces started trading at 5 am and were sent to more than 20 provinces across the country." Liu Binyu, deputy general manager of Shouguang Dili Agricultural Products Logistics Park Co., Ltd. introduced that today, the daily transaction volume of the logistics park can reach nearly 10,000 tons, and the daily transaction volume exceeds 30 million yuan.

　　The predecessor of Agricultural Products Logistics Park is the old vegetable wholesale market in Jiuxiang Village, Shengcheng Street. As early as 20 years ago, it was famous all over the country. In particular, the slogan "In Shouguang, there is no dish that can’t be bought, and there is no dish that can’t be sold" has attracted the attention of many vegetable farmers and distributors all over the country.

　　In 1998, after seeing the news of Shouguang on TV, Ji Zhennan, who lives in Heilongjiang, resolutely came to Shouguang vegetable wholesale market, starting from loading cars and watching cars for others, and becoming a business manager. Later, relying on his accumulated experience and contacts for many years, he founded his own fruit and vegetable company, mainly dealing in cauliflower, lotus root and cabbage. The business grew bigger and bigger, with a daily turnover of nearly 2 million yuan.

　　Recalling his own entrepreneurial process, Ji Zhennan was also very emotional: "In the old market, there were often cases of credit. In 2009, after the completion of the logistics park, the one-card settlement system was adopted, and cash was not needed, which reduced our labor costs and was very convenient. "

　　Today’s logistics parks not only realize the "buy and sell the whole country" of vegetables, but also make Shouguang vegetables develop from R&D, production to logistics and sales. Moreover, the "China Shouguang Vegetable Index" jointly developed by logistics parks and experts has become a barometer and vane of vegetable prices and trading trends in China. Shouguang has therefore become the center of vegetable distribution, information exchange and price formation in China.

　　Reproducible and scalable quality standards for promoting agriculture go first.

　　"At present, about 3,000 mu of greenhouses have been planted in the park, which will directly drive more than 12,000 poor households to increase their income and get rid of poverty. Farmers can not only get land rent and dividends from cooperatives, but also achieve employment at home. " Li Sheng, the chairman of Shandong Shouguang Lusheng Agricultural Group, introduced the vegetable industry precision poverty alleviation demonstration park built by the group in Yudu County, Jiangxi Province, a national poverty-stricken county. This modern park has brought multiple dividends to the surrounding farmers.

　　In recent years, driven by Shouguang’s leading local agricultural enterprises, Shouguang’s vegetable planting technology and mode are being accelerated to all parts of the country, and there are more than 200 agricultural parks that have been built and will be started soon.

　　Over the past 30 years, Shouguang people, while doing a good job in the development of their own vegetable industry, have continuously pushed Shouguang vegetable technology, talents, standards and problem-solving solutions to the whole country, driving farmers across the country to increase their income and become rich. Today, Shouguang has more than 8,000 agricultural technicians to build agricultural parks or guide vegetable production in 30 provinces, autonomous regions and municipalities all the year round.

　　However, due to the different technology and personal experience of enterprises, there have been some quality differences in the promotion process. However, in July 2018, with the National Vegetable Quality Standards Center landing in Shouguang, this problem was solved.

　　In less than a year, relying on the development advantages, successful experience and innovation potential of Shouguang vegetable industry, the National Vegetable Quality Standards Center not only drew up the whole industrial chain standards for tomatoes and cucumbers in solar greenhouses, but also took the lead in promoting the "six unifications" standardized management of unified agricultural materials, unified technology, unified management, unified testing, unified brand and unified sales in 18 newly-built key parks in the city, creating a model for the popularization and application of standards.

　　Entering Tian Jin Ryu Demonstration Park, one of the 18 parks, the advanced facilities and equipment are eye-catching: large-scale water and fertilizer integrated machine, multifunctional plant protection machine and intelligent temperature control realize intelligent management through the Internet of Things, which can save more than 60 labors per mu of vegetables every year, save more than 40% of water, improve the fertilizer utilization rate by 50%, and make every greenhouse and park a "green workshop" and a "green factory". These demonstration parks provide replicable and scalable experience models for accelerating the popularization and application of vegetable quality standards in the whole country and promoting the high-quality development of vegetable industry.

　　Standing at a new starting point, Shouguang has always adhered to the world vision and national orientation, focusing on production standardization, agricultural parks, vegetable brands, farmers’ professionalization, rural livability and equalization of public services, and constantly endowed the "Shouguang Model" with new connotations of the times, contributing to the creation of the "Qilu Model" for rural revitalization.

From October 11th to 13th, a think tank meeting, which has always been known as the authority of China urban rail development, will be held in Shenzhen, "China Urban Rail Transit Owners’ Leaders Summit 2021" to help build a smart urban rail and a strong transportation country.

Taking this opportunity, as the organizer of this conference, Shenzhen Metro will also hold a TOD brand launch conference with the theme of "Arriving at Unlimited Possibility" on October 13th, sharing the pioneering experience of how to use the "track+property" model to continuously feed back the construction and operation of rail transit and build a three-dimensional, efficient and intensive urban ecological space.

Behind the TOD model, which has aroused heated discussion in the industry, there are exciting blueprints:

By the end of 2020, 29 cities in China have carried out TOD comprehensive development, with a total land reserve of nearly 50 million ㎡ and an income increase of about 17 billion yuan. According to the international experience, almost all prosperous areas have central cities as their main platforms, and a strong rail transit network is often their important infrastructure. For example, the rail transit and TOD layout extending in all directions in San Francisco Bay Area, new york Bay Area and Tokyo Bay Area are examples.

In contrast, Guangdong-Hong Kong-Macao Greater Bay Area is still in the initial stage of TOD territory expansion in metropolitan area, but Shenzhen, the core city, has made a breakthrough from it, explaining the story of urban double engine with urban rail construction and TOD development mode.

Race with the Times: China Urban Rail Transit Towards the New Blue Ocean

As the saying goes, "If you want to be rich, build roads first".

The road is clear, and all industries are prosperous. From China’s first urban rail line, Beijing Metro Line 1, on October 1, 1969, the 8,449-kilometer urban rail transit line that has been put into operation in 49 cities now ranks first in the world (including 6,641 kilometers of subway lines); From being a hundred years behind (the world’s first urban rail was the London Metro, which was opened to traffic in 1863) to becoming a new national business card, the China urban rail has completed a leap-forward development at a speed that shocked the world.

This criss-crossing urban rail crossing mountains and seas is a symbol of urban roads in the new era, and it also carries the dreams of hundreds of millions of people in China, and embodies the Chinese dream of the great rejuvenation of the Chinese nation to go far away and reach infinite possibilities.

According to incomplete statistics, in 2020, the domestic urban rail network completed a total of 17.59 billion passenger trips, which is equivalent to carrying the total population of the earth more than twice. In the same year, the proportion of urban rail transit passenger traffic in the total public transport passenger traffic nationwide was 38.7%, up 4.1 percentage points year-on-year; Among them, the passenger traffic of urban rail in six cities, including Beishangguangshen Ningrong, accounts for at least half of the country.

Data source: China Urban Rail Association, calculated from the monthly passenger traffic data of central cities published by official website, Ministry of Communications.

Today, China’s economy continues to develop steadily, but the traffic congestion problem is becoming increasingly serious. Undoubtedly, the construction of urban rail transit has been strongly supported by national policies, and it has moved from a big urban rail country to a strong urban rail country.

During the Tenth Five-Year Plan period, the development of urban rail transit was included in the plan development outline for the first time at the national level, and it was regarded as a major strategy to stimulate the sustainable development of the national economy, especially the economy of big cities.

In 2019, the country launched a new infrastructure strategy. Among the seven key infrastructure areas, the construction of "urban rail transit" is impressively listed;

In the first year of the 14th Five-Year Plan, the Draft Outline of the 14th Five-Year Plan and the Long-term Target in 2035 also proposed that the mileage of urban rail transit in China will increase by 3,000 kilometers during the 14th Five-Year Plan period, and it is estimated that the cumulative passenger traffic will exceed 100 billion passengers during the 14th Five-Year Plan period, and the accumulated investment is expected to reach 1,818.8 billion yuan.

Even if the policy dividend is put aside, urban rail is still a transportation system that competes with the times and has strong endogenous development momentum.

First, from the demand side, even if China is stronger than first-tier cities such as Beijing and Shanghai, its urban rail density still lags far behind that of international metropolises.

Under the background of deepening urbanization, the formed urban agglomerations and metropolitan areas will further release the transportation needs such as logistics and people flow, followed by the continuous increase in the number of private cars, with traffic congestion as a typical urban disease. This means that in the foreseeable future, domestic urban rail transit construction still has a large room for growth.

Second, from the supply side, as of the end of 2020, the network planning of 61 cities nationwide has been approved and under construction, with a line length of 6,797.5 kilometers, accounting for 80% of the total line length currently in operation. Take Shenzhen as an example. According to the plan put forward by the Municipal Transportation Work Conference, by 2025, Shenzhen will build "640 kilometers of urban rail+220 kilometers of railway".

On the other hand, there are more than 100 cities in China that are planning rail transit, and more cities that meet the requirements for subway declaration still have no subways, which means that more supply reserve troops are ready to go. Therefore, it can almost be concluded that with the promotion of "urban integration", the national urban rail system will continue to gain development momentum.

Urban rail, which blooms everywhere, is changing the space-time layout of a city by means of point-to-line and line-to-network, and also broadening the road for the city to a better future.

The orderly operation of a modern city depends on public transportation, and urban rail transit is the first choice for public transportation. Further exploration, the aorta of domestic urban rail transit is the subway.

Source: China Urban Rail Transit Association, as of June 30, 2021.

As an important part of the urban public transportation system, if the basic function of making travel more convenient and faster is put aside, the construction and operation of the project will also promote the development of property and commerce along the surrounding areas, and often form a unique "subway economic belt".

After all, travel is not an end, but arrival.

Exploring the "city" in the city: TOD model empowers the diversified and efficient development of the city

"People come to cities to live, and people live in cities to live better." -Aristotle

China’s urban rail construction has entered the fast lane of speeding up. From a subway to rail transit in major cities all over the country, innovation is still going on, and China’s wisdom is creating the future. Then the soul torture is coming. Besides providing increasingly convenient and fast transportation, what kind of surprises will the urban rail bring to people’s lives?

Due to different personal preferences, the answers are bound to be varied. But the TOD project will be one of the popular answers, which represents people’s yearning for a better life in the era of urban rail transit.

What new species is TOD?

In the past, the development of domestic cities was mainly based on spatial expansion, but now the logic has changed to spatial optimization.

Take Shanghai, where the density of domestic urban rail is at the forefront, when the domestic TOD project has not been introduced, because the subway line construction has been spreading in various districts of Shanghai, the real estate is often developed wherever the rail is built, that is, the "subway house" in the usual sense. Although in this mode, Line 1 has driven Xinzhuang, Line 9 has driven Songjiang and Line 11 has driven Jiading … But this simple and rough development mode is obviously not a long-term solution for big cities with increasingly insufficient land space and increasingly congested cities, and new urban planning urgently needs a dose of "TOD medicine".

When it comes to TOD, I believe that the deepest impression of most people is "the subway is covered". In the ordinary urban rail depot, vehicles used to park in the open air. If a large concrete cover is added on it, then this "cover" is equivalent to re-creating a valuable building land. Under the cover, new properties are built on the cover, which is commonly known as "superstructure property (subway roof)". This creative development idea, on the one hand, solves the problems of land shortage and housing difficulties, on the other hand, realizes the property feeding back to the urban rail and ensures the sustainable development of the urban rail property.

Comparison of the effect of "building property"

It should be noted that the "superstructure" only reflects one aspect of the TOD project, not the whole picture. In the early years, the United States took the lead in proposing a new mode of urban development TOD: transit-oriented-development, that is, an urban development mode centered on public transportation hubs, and establishing a central square or city center with a radius of 400-800 meters. It is no exaggeration to say that the standard TOD is a "mini city center". You can stay in it for a long time, but you can always easily communicate with the outside world.

Therefore, the TOD concept project is by no means equivalent to a subway house. It is not a single residential/commercial area built on the urban rail, nor a simple combination of various formats, but a fusion of life scenes: office, business, residence and other public buildings and landscape environments are integrated into one project, and people can enjoy a suitable street network pattern, work and living space.

How is the excellent TOD practiced?

In the Shinjuku subway area of Tokyo, there are 17 rail lines gathering here, with 3.64 million people entering and leaving the gate/day, and there are 178 subway exits, the number of which is staggering. It has long been certified by Guinness World Records as the subway station with the largest number of users in the world.

In order to strengthen the link between the station and the surrounding commercial facilities, the developer upgraded the whole area into a more diversified "international exchange city". For example, in the aspect of transfer planning, the seamless connection of underground station, station business, above-ground station and above-ground business has been achieved; In terms of staying experience, more green nodes such as green terraces are added to "embellish" it.

It is not only the newly planned administrative and commercial center in Tokyo, but also a commercial district where department stores and commercial streets gather, and there are many famous enterprise headquarters, which makes the purchasing power of the huge floating population and the empowerment of the city have been qualitatively improved.

Looking back to China, the TOD project has a longer cycle than ordinary property development projects. According to the 3-4 year cycle, the number of follow-up plans, investment demand and business income of the sector may be fed back during the Tenth Five-Year Plan period. In addition, many late-developing cities, such as Guiyang, Nanchang and Lanzhou, are still in the initial stage of rail transit construction, and the lines have not yet been networked. The primary and secondary linkage of land business and TOD project planning have not yet been carried out due to the scale of rail transit. However, in the long run, with more and more urban rail transit plans approved, the market prospect of TOD project development is very broad.

In recent years, many mainland cities have also taken the lead in emerging a number of high-quality TOD projects.

Shanghai’s largest transportation hub, Dahongqiao, is home to airports, high-speed rail, urban rail and expressway. The Vanke Sky City project, which is entrenched here, draws lessons from the Japanese TOD model. Around Xuying Road Station of Line 17, the core of planning is the concept of 15-minute life circle mentioned in Shanghai 2035.

At the moment when the subway construction is in full swing, the TOD exploration road of Shenzhen Railway Real Estate, a wholly-owned subsidiary of Shenzhen Railway Group, also has many remarkable points.

Innovating "Track+Property" Mode and Practicing TOD Development Concept

In the eyes of the industry, TOD requires developers’ overall consideration ability and comprehensive coordination ability because it involves many stakeholders and the design scheme is complex. At present, there are few enterprises that have successfully implemented TDO mode in China, and Shenzhen Railway Real Estate, a subsidiary of Shenzhen Railway Group, is one of the few leading explorers.

The essence of the "track+property" development model of Shenzhen Railway Real Estate Co., Ltd. is the synchronous planning, synchronous design and synchronous construction of superstructure (Shenzhen Railway Real Estate Co., Ltd.) and subway line construction (Shenzhen Railway Construction Co., Ltd.), and provides financial support for the sustainable development of urban rail transit through the development of subway superstructure.

Perhaps it is also due to the deep coupling with the parent company Shenzhen Metro Group in business collaboration. Shenzhen Railway Real Estate Co., Ltd., which covers two core businesses of property development and hub, has won the top three of the "Top Ten Comprehensive Strength of Shenzhen Real Estate Development Industry" for five consecutive years, and achieved sales of over 10 billion yuan for six consecutive years. As of September, 2021, Shenzhen Railway Property Co., Ltd. has obtained the comprehensive development right of 16 superstructure projects along the track, with a total development scale of 11.07 million ㎡, of which the built delivery area is about 3.9556 million ㎡, the construction area is about 5.44 million ㎡, and the construction area is about 1.666 million ㎡.

The major TOD projects under Shenzhen Railway Real Estate Co., Ltd. have been completed one after another, which actually reflects the new changes in the development model of TOD in recent years.

First, from "single station independent development" to "district overall planning, station-city integration"

Take the Qianhai International Hub Project of Shenzhen Railway as an example. The planned hub and superstructure projects of this project have a total land area of 20 hectares and a total construction area of about 2.159 million ㎡. Upon completion, it is estimated that the total passenger flow will reach 750,000.

The planning of the project skillfully adopts the design concept of "integration of stations and cities". From the overall planning, Qianhai Hub connects Guangdong and Hong Kong with five lines, and the three-dimensional public transportation is seamlessly connected with the high-end urban complex, so as to build an intensive and three-dimensional 24-hour dynamic community based on Shenzhen Qianhai and radiating the Pearl River Delta and Hong Kong, shape the image of an international modern city window, and form the landmark and regional core of Qianhai District.

In terms of traffic design, on the premise of ensuring efficient transfer of internal pedestrian traffic, it is also connected with surrounding buildings or plots through underground, ground and second-floor pedestrian systems to realize fast and convenient pedestrian contact between the project and the surrounding areas.

Finally, the property and hub implement the concept of "integration" in the whole process of the project through integrated design management, planning, construction and operation.

In the future, in such a comprehensive community with mixed functions, the subway is carrying dreams to shuttle day and night. On the one hand, there are endless trains, on the other hand, there are bustling commercial and office areas, and on the other hand, it is a peaceful and quiet livable place.

Second, the transformation from "spatial planning" to "functional planning, spatial planning and integrated design"

The Jin Shang Garden of the subway, jointly presented by two state-owned enterprises, Shenzhen Railway Group and Zhenye Group, is seamlessly connected with Liuyue Station of Metro Line 3, and is a large-scale complex covering residential, apartment, commercial and sports parks.

The project innovatively combines the two values of "subway" and "park", and is adjacent to a large sports park in functional planning, including tennis courts, basketball courts, circular jogging tracks and other facilities; In space planning, brand businesses such as Boxma Xiansheng, China Film International Cinema, Starbucks and Decathlon are gathered to build a metropolis experience.

Third, the transformation from "space design around the site" to "characteristic scene creation" serving people’s life, travel and work needs.

The Shenzhen Railway Reading Mountain Garden Project can be said to have left a rich and colorful stroke for the construction of TOD characteristic scenes of Shenzhen Railway Real Estate. The project is positioned as an ecological zone of universities, a subway metropolis and an elite quality residential area. It is a high-grade elite quality community integrating housing, schools and supporting businesses. Because it is adjacent to well-known universities such as Peking University, Tsinghua and south university of science and technology of china, it has successfully created a characteristic scene of a humanistic university with mountains.

Fourth, change from "development and construction" to "comprehensive operation"

As the first masterpiece of urban high-end residential buildings created by Shenzhen Railway Property, Shenzhen Railway Yifu Project is a 750,000 ㎡ humanistic and ecological complex integrating high-end residential buildings, colorful businesses, sports parks and nine-year education facilities. From the beginning of the design, the project was based on the thinking of comprehensive operation, instead of relying too much on one subway station, it was built on four subway stations: Antuo Mountain, Shenkang, Qiaocheng North and Shenyun. The Antuo Mountain area is connected with Xiangmi Lake and OCT, and it is expected to become a new sample of urban mountain residence.

From "Qianhai International Hub Center" to "Shenzhen Railway House", it is a brand-new exploration and breakthrough again and again for the younger Shenzhen Railway home buyers in the young cities. Relying on the deep accumulation of Shenzhen Railway Group for more than 12 years, Shenzhen Railway Real Estate will continue to deepen the TOD model and build a more anticipated "track+property" map.

Of course, beyond the transformation, we need more persistence. Many TOD classic concepts, such as people-centered, efficient land opening and efficient accessibility, have always run through the long journey of Shenzhen Railway to help residents on the urban rail reach infinite possibilities.

　　On February 2nd, a ceremony was held in Maoxian People’s Hospital, where 15 medical staff drank wine to five doctors who came to support jianyang city People’s Hospital. Five masters also presented professional books to the disciples, put on stethoscopes for them, and told them to constantly improve their ability to serve patients in their studies.

　　The ability construction of health talents is the key to cure diseases for the masses. On December 14th last year, the Provincial Health and Family Planning Commission innovatively implemented the "mentoring" project of medical and health counterpart support in poverty-stricken areas, aiming at transferring knowledge, helping institutions and bringing apprentices, and building a willing, capable and supportive local talent team for poverty-stricken areas, which is a new focus of health and poverty alleviation in our province.

　　Medical institutions at all levels acted quickly. At the beginning of the new year, 9 medical staff from the Provincial Orthopedic Hospital went to Xuanhan County and Songpan County, 10 experts from Panzhihua Central Hospital came to Muli County, and 50 medical staff from Neijiang City went to 19 medical institutions in 17 poverty-stricken counties … Teams came to the recipient medical institutions to help build health talents in poverty-stricken areas.

　　Teacher and apprentice

　　Create qualified local doctors

　　On January 8th, Zhang Hongmin, an orthopedic surgeon of Suining First People’s Hospital, came to Tonghua Township Health Center in Lixian County on the first day, and signed a "mentoring" agreement with the hospital, and also formulated the teaching and village doctor training plan for this year’s health center. "In addition to relieving the pain of local people, it is more important to train qualified local doctors so that they can be independent in the future."

　　On January 17th, Zhou Xuebing from Taoping Town came to Tonghua Township Health Center. The fourth toe of his left foot was red, swollen and painful for 4 days, and an abscess under the nail was formed in the affected area. Zhang Hongmin took Yu Fan, a disciple, to remove Zhou Xuebing’s toenails after local anesthesia, and instructed Yu Fan to dress the wound. "After many instructions from the teacher, I can now complete the nail removal operation myself." Yu Fan is very excited.

　　On January 12th, Ren Zhen (pseudonym) became the first local beneficiary of laparoscopic tubal ligation in Danba County People’s Hospital. She was operated by Kang Liping, the attending physician of Chengdu Sixth People’s Hospital who supported Danba County. Many local women of childbearing age choose tubal ligation for contraception, which causes great trauma and slow wound recovery. Kang Liping thought of using laparoscopic ligation, which not only reduces the pain of patients, shortens the hospitalization days, but also reduces the use of antibiotics. She learned that the hospital has laparoscopic surgical instruments, and the members of the department also have the basis to study laparoscopy, so she organized the doctors of the department to learn the relevant knowledge of laparoscopic surgery. Ren Zhen’s operation was very smooth, which also allowed local doctors to experience the operation process "zero distance". "I benefited a lot and gained a lot."

　　On March 6th, Tan Cuixia, Tang Hao and Luo Yang, members of the medical team of Chengdu First People’s Hospital in Leibo County, came to Wujiao Village and Temen Village for a free clinic, together with their apprentices. They diagnosed diseases, measured blood sugar, performed B-ultrasound for local people, and carried out traditional Chinese medicine diagnosis and treatment such as moxibustion and massage. Tan Cuixia guided his apprentice Shi Xiaomin to operate. After three days of free clinic, the disciples learned medical skills from the teacher.

　　Treat an emergency

　　The patients here need us.

　　From the city to the poverty-stricken areas, the counterpart support team members are thinking about how to leave their medical experience, pass on their skills to their apprentices, and improve the level of the aided medical institutions as soon as possible.

　　This year’s Spring Festival, the Fifth People’s Hospital of Chengdu supported the captain of the medical team of sertar county Hospital to stay in sertar county Hospital with team member Yao Zuoyi. "This kind of Spring Festival is more memorable."

　　On New Year’s Eve, after rounds, they prepare a reunion dinner with the local doctors on duty and jump in the pot farm with the local people. While greeting each other, a patient with a broken metacarpal bone was taken to the hospital, and Yao Zuoyi immediately examined and treated the patient. During the Spring Festival, they treated several emergency patients, such as acute pancreatitis and full-scale burns, and felt more and more that there were limited medical conditions and a lack of doctors, and there were still many things to be done. What the two doctors said most in video communication with their families was, "The patients here need us."

　　On the morning of March 16th, Hu Zhipu and two local apprentices made rounds in the maternity ward of Derong County Maternal and Child Health Family Planning Service Center, and explained the reasons for the patient’s treatment plan to the apprentices. As the attending physician of Qingyang District Maternal and Child Health Family Planning Service Center in Chengdu, Hu Zhipu has been in Derong County for more than a year, and only goes home on major festivals. "I think of this as another home." Hu Zhipu also contacted the caring team in Chengdu to raise common medicines and clothes for the poor people in Tibetan areas. On the weekend, she and the medical team visited the village to carry out free clinics. "Although the clothes we sent are not the latest and our technology is not the best, we must send love." Once, she suffered from acute attack of cholecystitis caused by stone incarceration. At that time, there were many patients in the hospital who needed emergency surgery. She unplugged the infusion needle and joined the medical team.

　　Innovate the new path of talent training in poverty-stricken areas

　　"The’ mentoring’ project will innovate the training method of health talents in poverty-stricken areas and will supplement the existing talent training plan." Relevant persons of the Provincial Health and Family Planning Commission said that this assistance action has established a stable pairing relationship, and implemented mentoring, remote diagnosis and treatment guidance, and remote teaching, so as to strive that by 2020, local medical and health personnel in poverty-stricken areas can meet the medical and health service needs of local people.

　　"What the masses are most worried about is the medical skills of doctors. The’ mentoring’ project will play a good role in promoting talents through measures such as mentoring." The relevant person in charge of the Health and Family Planning Bureau of Enyang District, Bazhong City said.

　　The "mentoring" project, which "disseminates" knowledge and skills, adopts clinical training, process teaching and special training to improve the four professional qualities of local talents at county and township levels in a relatively short period of time, such as academic qualifications, professional titles, practicing capital and job skills. "Helping" means helping institutions and disciplines, and adopting the methods of sinking the technical team, sinking the discipline team and sinking the management team, etc., so as to promote the state and county level institutions and central health centers to reach the standard and grade, and the disciplines are developed. "Bringing" means bringing individuals and teams, and adopting the methods of mentoring, remote diagnosis and treatment, quality review, etc., so that the help objects can grow into talents as soon as possible.

　　In order to stop going through the motions, the Provincial Health and Family Planning Commission has set a clear goal for the "mentoring" project. Every year, 350 general practitioners will be transferred to jobs and 7,000 qualified village doctors will be trained. By 2020, the goal of "one township, one general practitioner" and "one village, one doctor" will be realized. In principle, there should be at least one belt and three for medical institutions, at least one belt and two for women and children’s institutions, at least one belt and two for disease control and supervision institutions, and at least one belt and two for central health centers to ensure the coverage of major departments (majors) and personnel within three years; Focus on cultivating the ability of diagnosis and treatment of common diseases and frequently-occurring diseases, identification and referral of acute and critical diseases, and monitoring and disposal of infectious diseases.

　　The United States unilaterally provoked a trade war with China, which affected the nerves of overseas Chinese. What pains and opportunities does Sino-US trade friction bring to China’s economy? How have the economies of various countries been affected by the Sino-US trade situation? How does Sino-US trade friction affect the world economic structure? This newspaper interviewed overseas Chinese from many countries and asked them to talk about their personal experiences and feelings.

　　There is no winner in trade friction

　　In San Francisco, USA, Cai Wenyao, consultant of the American Chinese Chamber of Commerce, found that it was cheaper to buy corn. "The price of corn has dropped from 0.5 US dollars to 1 US dollar and 4 US dollars. This price fluctuation may be related to the limited export of corn in the United States and the dumping of corn in the domestic market." Cai Wenyao said.

　　"The countermeasures taken by China now have a great impact on the middle and lower classes in the United States. On the one hand, products imported from China increase tariffs, and manufacturers pass the costs on to consumers, which indirectly increases the living costs of ordinary people; On the other hand, the countermeasures of agricultural products have directly affected the sales of agricultural products, the prices of agricultural products have also dropped significantly, and farmers’ income has decreased. " Cai Wenyao said.

　　Not long ago, a report in a local newspaper in the central part of the United States caught the attention of Zhang Jun, an American political and legal scholar. It was reported that China’s imposition of punitive tariffs caused panic and concern among the American people.

　　"China levies tariffs, and enterprises in the agricultural and manufacturing industrial chain in the United States bear the brunt. Sino-US trade friction not only directly affects the interests of related industries in the United States, but also exerts great psychological pressure on employees in other related industries. " Zhang Jun said.

　　Zhang Jun believes that in recent years, with the rapid economic growth of China, the economic complementarity between China and the United States is gradually decreasing and the competitiveness is increasing. One of the reasons for the trade friction between China and the United States is that the United States regards China as a potential rival in economic and trade relations.

　　For China, the high tariff policy of the United States will have a great impact on China’s international trade in the short term, but it will also provide a warning for China’s long-term economic and trade development model. "To some extent, we should ‘ Thank you ’ This trade friction has forced China enterprises to improve their core technological capabilities, which has stimulated and promoted China’s economic transformation and supply-side reform. " Jiang Feng, editor-in-chief of the New Overseas Chinese News of Japan, said.

　　"If the warming of trade friction causes instability in Sino-US relations, it will have a negative impact on the world economy and the international situation." Nan Gengxu, chairman of Global Wide Area Media Group, said.

　　Countries join hands to tide over the difficulties.

　　"With the development of world economic globalization and trade liberalization, the global industrial chain division of labor system and value chain have been built, and the interests of all countries in the world are deeply blended, and they are all prosperous and lose." Jiang Feng said.

　　Since Trump took office, the United States has set off trade protectionism and unilateralism around the world, and almost all the world’s major economies, such as China, the European Union and Canada, have been affected by American bullying. Overseas Chinese in various countries have a personal experience of this.

　　On the one hand, Sino-US trade frictions seek other markets for goods blocked by Sino-US trade, on the other hand, they attract goods from other countries to make up for the trade gap between China and the United States. In the trade conflict provoked by the United States, all countries in the world meet challenges and opportunities and tide over difficulties together.

　　"Sino-US trade friction has objectively narrowed the trade relationship between China and Europe." Shi Zhongsheng, president of the French-Fujian Chamber of Commerce and Industry, believes that the European economy has also been greatly affected by the US trade protection measures, and European enterprises can make up for the gap in China’s demand for American products to a certain extent. Sino-US trade friction provides opportunities for China to seek cooperation with Europe.

　　On July 9th, China and Germany signed more than 20 agreements with a total amount of 30 billion US dollars in Berlin, involving cooperation in the fields of vocational education, climate research, autonomous driving and medical and health care, including more than 10 agreements signed by BMW Great Wall, BMW Brilliance and Daimler Tsinghua.

　　Zheng Rongchang, vice chairman of the British Chinese General Chamber of Commerce, believes that China’s cooperation with Britain and countries in continental Europe will provide China with a broader perspective and ideas to deal with Sino-US trade frictions. The enlightenment of Sino-US trade friction to China is not only in the economic and trade field, but also in scientific and technological innovation, cultural exchanges, cultural values, personnel training and other aspects. Britain and European countries, which have a long history and humanistic connotation and advanced technology research and development capabilities, have more common language and complementary advantages with China, and are expected to achieve closer and deeper all-round cooperation.

　　"The impact of Sino-US trade friction on Japan can be said to be ‘ One is happy, the other is sad ’ 。” Jiang Feng said that China’s counter-measures against the United States have restricted American products from entering China, which has affected the operating conditions of Japanese investment enterprises in the United States, but also provided opportunities for Japanese products to enter China and promoted Japan’s expansion of exports to China.

　　On July 17th, the Japanese government and the European Union signed the "Europe-Japan Economic Partnership Agreement" and issued a statement saying that Japan and Europe will promote high-standard, free, open and fair free economic relations, safeguard the multilateral trading system centered on the World Trade Organization and fight protectionism. Jiang Feng believes that the Japanese government’s move has shown Japan’s position in Sino-US trade friction.

　　For Oceania countries that rely heavily on import and export trade, Sino-US trade friction has brought more uncertainties to the international trade of Oceania countries.

　　"As a country that is particularly dependent on exports and the World Trade Organization system, New Zealand is eager for a stable international trade environment and clear and enforceable trade rules." Sun Bangbang said.

　　For the vast number of developing countries, Sino-US trade friction has not affected the tide of cooperation and development among developing countries. "China has a very large consumer market, China has reduced the import of American goods, and many companies in Thailand and Southeast Asia have seen opportunities." Jason, consultant of Philippine Red Candle Chinese Education Foundation, said that the multilateral win-win cooperation model of China’s Belt and Road Initiative has gradually become an international consensus.

　　Hoping that China and the United States will seek a win-win situation

　　"The policies of the United States and the style of behavior of leaders are becoming more and more unpredictable. Intermittent trade frictions between the two big countries may be an inevitable trend in the future." Nan Gengxu said.

　　At present, Sino-US trade friction is at a stalemate stage, and the future development trend is characterized by complexity and long-term. China is ready to deal with Sino-US trade friction for a long time, and seek a way out from the world markets while rationally dealing with trade friction with the United States.

　　Sun Yibang believes that the Sino-US trade friction reminds all countries in the world that they should conform to the trend of globalization and standardize the operation of economic globalization instead of abandoning the process of resisting globalization.

　　"At present, the development trend of the world economy is ‘ Castle peak cannot be covered, after all, it flows eastward ’ 。” Jason said, "Economic globalization is irreversible, and it is unwise for any country to set up trade barriers." In the future, Sino-US trade friction still needs rational consultation and negotiation between the two sides to seek a win-win situation on the basis of trade liberalization.

　　Zhang Jun believes that the future development trend of Sino-US trade friction remains to be seen, but the trade war is not the result that all countries in the world want to see. "All countries in the world have this kind of appeal, hoping that China and the United States can reach a new trade order through bilateral or multilateral negotiations. Most people hope that this high tariff policy is only a means, not the final result. "

　　At the same time, close cooperation with developing countries will provide a new way for China to deal with trade frictions for a long time. "In the future, as a developing country, Africa will definitely not miss the progress and opportunities brought by China’s opening up, and China will continue to provide more opportunities for promoting the prosperity and growth of international trade." Nan Gengxu said, "Ten years ago, African entrepreneurs first thought of the United States when they went abroad to invest, but now their first thought is probably China."

　　The prehistoric creatures

　　Intern reporter Dai Xiaopei

　　In the evolutionary history of dinosaurs, one of the biggest mysteries is: Are there aquatic dinosaurs? Although we know that ichthyosaurs, plesiosaurs and canglong all live in water, according to their position on the evolutionary tree, they are not strictly dinosaurs, but only close relatives of dinosaurs. So why are aquatic dinosaurs so rare?

　　Spinosaurus is an atypical aquatic dinosaur?

　　In fact, among the dinosaur fossils found, there are not dinosaurs that did not live in water at all.

　　In 1912, people discovered a kind of theropod dinosaur in Egypt — — Fossils of Spinosaurus, which lived in the Cretaceous period from about 110 million to 93.5 million years ago.

　　According to the early data released by scientists, Spinosaurus was 12.6 to 18 meters long and weighed 7 to 20.9 tons. In recent years, more complete specimens support early research, and scientists found that Spinosaurus could grow to a length of 15 to 15.6 meters. However, the latest data estimate that its weight is 6.4 tons to 7.2 tons. Unlike most dinosaurs, Spinosaurus had some unique spines on its back, forming a sail-like structure. According to public information, the spines on the back of Spinosaurus were at least 1.65 meters long. The spine of Spinosaurus is an extension of its vertebrae, which researchers believe can help Spinosaurus regulate its body temperature or show its unique charm.

　　"After comparing Spinosaurus with crocodiles, people think that Spinosaurus may be aquatic." Xu Xing, a paleontologist at the Institute of Vertebrate Paleontology and Paleoanthropology of China Academy of Sciences, told the Science and Technology Daily reporter that according to the skull shape of Spinosaurus, it was found that the skull of Spinosaurus was long and narrow, similar to that of modern crocodiles. Specifically, the mouth is slender, and the direction and size of teeth help it catch fish and fix its prey in the mouth.

　　In addition, by analyzing the fossils of individual Spinosaurus, some scientists found that there were fish scale residues in the stomach contents of Spinosaurus. "This shows that Spinosaurus ate creatures in the water, and it can be speculated that Spinosaurus may live on the shore or in the water." Xu Xing said that another evidence that Spinosaurus lived in water is that studies have found that the isotopic composition of Spinosaurus bones is close to that of aquatic animals.

　　However, Xu Xing stressed that there is no very conclusive evidence that Spinosaurus must have lived in water. "Because Spinosaurus didn’t have a fin-like structure like aquatic animals such as sea lions or seals. This shows that Spinosaurus cannot live completely in water and is not a typical aquatic animal. " He said that according to the existing findings, it is not easy to judge whether Spinosaurus lived in the water or on the shore for a long time.

　　"According to the teeth and skull of Spinosaurus, people think that Spinosaurus mainly lived by eating fish, but Spinosaurus is just a kind of dinosaur with a special feeding habit, and generally speaking, Spinosaurus just goes into the water to prey and then returns to land life. Therefore, we cannot put forward ‘ Aquatic dinosaur ’ The concept. " Xing Lida, an associate professor at China Geo University, said.

　　Dinosaurs were aquatic animals?

　　Some scientists believe that dinosaurs were originally aquatic animals. This statement stems from a puzzle: how did the slender legs of dinosaurs support its huge body? Brian Ford, a cell biologist at Cambridge University in England, tried to explain that dinosaurs mainly lived in water and supported their bodies by buoyancy. He said that dinosaurs swam in the lake most of the time, and their tails provided assistance, and their footprints were printed into the mud.

　　According to Ford, it can explain why archaeologists often dig dinosaur footprints, but there are few traces of dinosaur tails. Compared with modern large animals such as elephants and rhinoceroses, dinosaurs had small legs but fat tails.

　　"It makes sense to think that dinosaurs lived in water." Ford said, "dinosaurs used water to support their weight, float their tails, regulate their body temperature and get food."

　　However, Paul Barrett, a paleontologist at the Natural History Museum in London, believes that this statement makes no sense. He said that with the help of the principle of load-bearing structural engineering, researchers have proved that the strength of dinosaur leg muscles is enough to support its body to walk easily on land. Moreover, dinosaurs had difficulty breathing and walked slowly in the water. "They may live near water, and sometimes they go into the water to cool off, but I don’t accept the theory that they live in water." Paul said.

　　In 2007, scientists found traces of dinosaurs’ claws at the bottom of the water in the Carmelos basin in northeastern Spain, which became conclusive evidence that "dinosaurs could swim". In 2011, Chinese and American paleontologists found a group of strange footprints with only toe marks and no heels in Chicheng County, Hebei Province. Experts believe that this is the hard evidence of dinosaurs playing in the water — — Tracers leave scratches on the bottom of the lake after entering the water. As the depth of the lake increases, their feet can touch less and less water bottom, and their footprints gradually weaken, and their three toes can not be completely preserved.

　　Completely aquatic dinosaurs don’t exist?

　　Although there is evidence that some dinosaurs lived in water, Xing Lida still opposed the concept of "aquatic dinosaurs". “‘ Aquatic dinosaur ’ It is only a hypothesis put forward in recent years, but it is extremely easy to include Syngnathus, Canglong, plesiosaur, etc., confusing concepts. "

　　Xu Xing also told reporters: "According to the existing research, there are no pure water dinosaurs. Let’s just say that there is some evidence that dinosaurs lived in water for some time. The limbs of plesiosaurs, ichthyosaurs or sea lions and seals will undergo height changes to adapt to life completely in water, but there is no evidence that such dinosaurs exist at present. "

　　Strictly speaking, no real aquatic dinosaurs have been found. Xu Xing believes that there are two possibilities. First, dinosaurs did not give priority to occupy the water niche in the era when they lived. At that time, the water environment might be occupied by crocodiles and other aquatic animals. Second, there may be aquatic dinosaurs, but they have not become mainstream species, and the fossils of such dinosaurs have not been preserved or discovered.

　　"In recent years, with the deepening of field trips, people have discovered more and more strange dinosaurs. The current fossil record has not fully revealed the diversity of dinosaurs. " Xu Xing said that the original fossil record is deficient, some deficiencies may be remedied, and some deficiencies may exist forever.

　　What’s the point of studying dinosaurs and even arguing about whether dinosaurs were aquatic or terrestrial?

　　"First of all, it can prove some evolutionary phenomena. Species are always changing, such as from big to small, from land to air. Scientists hope to reveal the law of change. " Xu Xing said that the current ecosystem is called the world of birds and flowers, characterized by beautiful birds and flowering plants, and this ecosystem evolved from the Mesozoic ecosystem dominated by dinosaurs. We need a lot of data and fossil records to reveal this evolution process.

　　At the same time, scientists should also reveal which factors affect the evolution of life, such as genes or environment. "It is also important for human beings to understand their own lives to understand the laws of the evolution of all things." Xu Xing said.

　　This dinosaur can also swim and hunt in the water.

　　At the end of 2017, research teams from Italy and other countries discovered a new dinosaur fossil in the late Cretaceous strata of Mongolia, which was roughly waterfowl-like. This new dinosaur species was named Eichzka, commonly known as "duck dinosaur". "Duck Dinosaur" has a long and curved neck, and its forelimbs are fin-shaped. It can walk on land like a duck and swim with its forelimbs. They also have many tiny teeth suitable for eating fish. Another feature of "Duck Dinosaur" is that its beak and upper jaw have many small holes, which were once filled with nerve endings. This kind of mouth has a similar structure to the beaks of some waterfowl. This shows that "duck dinosaurs" may have preyed in the water or at the bottom of rivers and lakes.

　　To adhere to the guidance of Marxism in the field of philosophy and social sciences, the core is to solve the problem of why people are. General Secretary of the Supreme Leader pointed out at the symposium on the work of philosophy and social sciences that if China’s philosophy and social sciences want to make a difference, it must adhere to the people-centered research orientation. Without the people, philosophy and social sciences will not be attractive, infectious, influential and vital. The vast number of philosophical and social scientists in China should adhere to the view that the people are the creators of history, establish the ideal of learning for the people, respect the people’s dominant position, focus on people’s practical creation, consciously link personal academic pursuit with the development of the country and the nation, and strive to produce more research results that can stand the test of practice, people and history.

　　Adhering to the people-centered principle is the fundamental value of philosophy and social sciences.

　　Philosophy and social science takes the existence and development of human beings and society as the research object and content, so it is both "human" and "human". From the connotation point of view, society is made up of people, with people’s activities as its content, and the main body of social history is concrete and historical people. Therefore, the existing conditions of human beings, including health, civilization, cultural and technical level, and conceptual state, are the research contents of philosophy and social science; The essence of social development is the process of continuous improvement of human beings and their modes of existence (including modes of production and lifestyles), the overall evolution and progress of economy, politics, culture and society, and the pursuit of their reasonable ideal forms by people in different historical periods. Therefore, human beings are the basic elements and power sources for social existence and development. In essence, human activities take social practice as the essence, while social practice is a material activity on the one hand, and a dynamic activity on the other. This initiative is the concentrated expression of human rational spirit, and it is the basis for the existence of self-sustaining content of social development. "History is just the activity of people who pursue their own goals." Therefore, social and historical development is essentially "human". It can be seen that social development is both "human" and "human", which makes human beings get rid of the blindness of existence and development and transition to freedom.Make the development history of human society become the history of conscious activities.

　　Philosophy and social sciences have the functions of reflecting social existence, maintaining or criticizing reality, regulating social and human activities and innovation, and the value orientation of these functions is social development and human progress. Therefore, adhering to the people-centered principle is the fundamental value of philosophy and social sciences.

　　Philosophy and social sciences reflect the cognitive function of social existence, which makes human beings as social beings truly become conscious and active subjects; The function of philosophy and social science in maintaining or criticizing reality is to maintain the social, economic and political forms that are unified with the nature of human progress, and otherwise to criticize; The adjustment and control function of philosophy and social science means that people must constantly revise and improve their activity plans and activities according to the actual situation, so that human beings can stably grasp and control their own activities and March according to reasonable plans, scientific methods and correct goals; The innovative function of philosophy and social science means that it can transcend the limitations of social reality and create new ideas, and then change social reality, create new social state and promote human progress under the guidance of new ideas. It contains huge spiritual positive energy and directly affects the current situation and future state of human society.

　　坚持以人民为中心是历史唯物主义的根本原则

　　马克思主义是广大劳动者、人民群众的学说，群众路线是马克思主义的基本观点，以人民为中心、坚持人民主体地位是马克思主义的内在要求。一个半多世纪前，马克思、恩格斯在批判鲍威尔、施蒂纳等人唯心的历史动力论和个人创造历史的错误观点中，揭示出人民主体的科学内涵及其实现途径，创立了人民主体观。

　　历史唯物主义的基本观点有两条，一是物质资料的生产是人类社会赖以生存和发展的基础，二是人民群众是历史的创造者，是历史发展和社会变革的决定力量，前者从生产力和生产关系、经济基础和上层建筑的辩证关系，考察了人类社会的发展进程，揭示了人民群众在社会历史发展中的主体地位，后者揭示了推动社会历史发展的决定因素，指明了人民群众是推动社会不断发展、不断改革、不断完善的根本动力。历史唯物主义的这个基本原理告诉我们，以人民为中心是社会存在和发展的客观要求和根本原则。

　　坚持以人民为中心是马克思主义中国化的基本路径

　　近一个世纪以来，中国共产党人将马克思主义的人民主体观与中国革命、建设、改革的实际相结合，孜孜追求国家的独立富强和人民的自由解放、生活幸福。

　　Persisting in taking the people as the center is the historical responsibility of the vast number of philosophical and social scientists.

　　Philosophy and social science workers should establish the concept of learning for the people. Our party is a party that serves the people wholeheartedly, and our country is a country where the people are the masters of the country. The starting point and end result of all the work of the party and the country is to realize, safeguard and develop the fundamental interests of the overwhelming majority of the people. In order to make a difference in China’s philosophy and social sciences, we must adhere to the people-centered research orientation. Without the people, philosophy and social sciences will not be attractive, infectious, influential and vital. The vast number of philosophical and social scientists should consciously link their personal academic pursuit with the development of the country and the nation, and strive to produce more research results that can stand the test of practice, people and history; We should put social responsibility in the first place, take the social effects of academic research seriously, be the pursuer and disseminator of truth, goodness and beauty, win respect with profound knowledge, lead the atmosphere with noble personality charm, and achieve self and value in making a statement for the motherland and the people.

　　Philosophy and social science workers should earnestly study and answer the issues of the times that the people are generally concerned about. Contemporary China is experiencing the most extensive and profound social changes in the history of our country. This unprecedented great practice will certainly provide powerful impetus and broad space for theoretical creation and academic prosperity. The vast number of philosophical and social science workers should carry forward the excellent traditional cultural spirit of "making a heart for heaven and earth, making a life for the people, inheriting the past and learning from the past, and opening up peace for all generations", set the tide of the times, communicate the changes of ancient and modern times, and make the first sound of ideas, and actively make comments and suggestions for the party and the people. Only by listening to the voice of the times, responding to the call of the times, caring for the people’s feelings, and seriously studying and solving the major and urgent problems that the people are generally concerned about, can we truly grasp the historical context, find the law of development, and promote theoretical innovation; Only in this way can we really study and answer the major theoretical and practical problems faced by China’s development and our party’s governance, and put forward the correct ideas and effective methods to solve the problems; Only in this way can we truly distinguish between essence and phenomenon, mainstream and tributary, and put forward objective, accurate and testable views and conclusions; Only in this way can we truly not forget the original, absorb foreign countries and face the future, not only deeply study major issues related to the national economy and people’s livelihood, but also actively explore major issues related to the future and destiny of mankind, and scientifically reveal the great logic and trend of the development of the times.

　　The leadership and management departments of philosophy and social sciences should strengthen the construction of social science talents. To construct philosophy and social sciences with China characteristics, we should start with people and make contributions for a long time. We should take good care of, cultivate and use the five armies of philosophy and social sciences, focus on discovering, cultivating and gathering a group of thinkers, theorists, academic leaders and young and middle-aged academic backbones, and build a talent system of philosophy and social sciences with complete categories and echelon connection; We should conscientiously implement the party’s intellectual policy, respect labor, knowledge, talents and creativity, and achieve full political trust, active ideological guidance, create conditions at work, care for them in life, and do more practical things, do good deeds and solve difficult problems for them; We should respect the hard work and research achievements of philosophy and social science workers, take the initiative to deal with experts and scholars, make friends, and often listen to their opinions and suggestions; It is necessary to let talents with both ability and political integrity play a role in important posts, form a good incentive mechanism for cultivating talents in philosophy and social sciences, and promote the continuous growth of outstanding talents.

　　In short, adhering to the people-centered research orientation is the inherent requirement of the development of philosophy and social sciences, the soul and direction of upholding and developing Marxism, and the historical responsibility and working principle of the prosperity and development of China’s philosophy and social sciences under the new situation. We must not be afraid of hardships, work hard, care for the public and watch for the people, and jointly promote the prosperity and development of philosophy and social sciences with China characteristics.

　　Take the "life gate" in your own hands.

　　When it comes to carbon dioxide (CO2), people generally think that it is like waste wood, which is not only useless, but also one of the chief culprits of destroying the climate and causing global warming. So far, researchers have thought of many ways to deal with it, such as imprisoning it (curing and sealing it) and driving it into a water dungeon (drilling into the seabed). However, in the eyes of Zhang Xiangping, a researcher at the Institute of Process Engineering of China Academy of Sciences, CO2 is a good raw material, which is cheap and easy to obtain. For more than ten years, her ionic liquid team, under the leadership of Academician Zhang Suojiang, has been pondering how to efficiently convert and utilize CO2 and turn it into treasure.

　　Deal with stubborn guys and send activists as "lobbyists"

　　CO2 utilization is a major global strategic issue. In June 2016, the EU launched a plan to take CO2 utilization as a major research direction; Japan has formulated a road map for CO2 utilization planning; China’s National Development and Reform Commission and Energy Bureau listed it as a key task in the Action Plan. However, the activation and transformation of CO2 molecules has become one of the internationally recognized scientific problems due to the problems of difficult activation, complex reaction path and low product selectivity.

　　"CO2 is a common compound in the air, and it is not easy to transform and utilize it. As we know, CO2 molecule is made up of two oxygen atoms and a carbon atom connected by a solid double bond, if you want to ‘ Knock ’ It is quite difficult to open the carbon-oxygen double bond closely linked between them and reduce it to oxygen and carbon. " Zhang Xiangping said in an interview with the Science and Technology Daily reporter.

　　Zhang Xiangping further explained that direct bond-breaking activation of CO2 requires high temperature and high pressure, but if we can find other active molecules to be lobbyists, such as epoxy compounds, we can induce the activation of CO2 and make its transformation easier. In addition, it is necessary to add a "medium", that is, a suitable catalyst, to promote the efficient conversion of CO2.

　　In the past ten years, after many experiments, the research team has gradually found an effective "cadre" who will live up to its mission — — The ionic liquid catalyst with multiple active sites can not only activate the double bond of CO2, but also make the ethylene oxide (EO) that reacts with it become active and open the ring more easily, so that CO2 and EO can react together to synthesize ethylene carbonate, an important chemical raw material.

　　Zhang Xiangping pointed out that the team successfully prepared the immobilized ionic liquid catalyst through further chemical chain loading, which avoided the problems of easy loss and deactivation of homogeneous catalyst, difficult catalyst recovery, high energy consumption and impact on product quality.

　　Coup after coup, enhancing value for efficient use.

　　Efficient catalyst has been developed, and a matching reactor is needed to provide a suitable place for the reaction.

　　Zhang Xiangping said: "Compliance response — Flow — According to the law of transfer and coupling, the team optimized the internal components of the reactor, realized the uniform distribution of the flow field/temperature field, and innovatively developed a 10,000-ton ionic liquid gas-liquid-solid three-phase tubular reactor, and the heat released quickly during the reaction can be discharged from the system as soon as possible, so that the reactor does not overheat and realizes safe operation. "

　　On this basis, the research team adopted alcoholysis reaction — The coupling process strengthening technology of pressure swing azeotropic distillation can realize the optimal integration of the whole system heat network, greatly reduce energy consumption, significantly improve economy and reduce equipment investment.

　　"In terms of technology, it is necessary to design a whole process to connect the whole reaction and separation process in order to get the final qualified product from raw materials." Zhang Xiangping told reporters, "We have optimized the integration of material and energy in the whole process, and greatly improved energy consumption, efficiency, economy and product quality to meet the needs of enterprises and markets."

　　According to reports, with the support of the national key R&D plan "Clean and Efficient Utilization of Coal and New Energy Saving Technology", since May 2018, the project "New Technology for Efficient Synthesis of Important Chemicals by CO2" led by the Institute of Process Engineering of Chinese Academy of Sciences has designed and synthesized a functional ionic liquid catalyst with multiple active sites in the CO2 carbonylation reaction, realizing efficient conversion of CO2 under mild conditions. At the same time, a carbonylation catalyst meeting industrial needs has been prepared and a continuous reaction device has been built. Aiming at the alcoholysis reaction of vinyl carbonate, a catalyst with high activity and low cost was developed, a 10-ton/year alcoholysis continuous device was built, and a 10,000-ton industrial test device was established.

　　Open up a new path to synthesize multiple important chemicals

　　The technology of CO2 capture, utilization and storage (CCUS) is one of the main ways to realize low-carbon emission of coal in China, and the high-value utilization of the collected CO2 can not only reduce carbon emission and alleviate the greenhouse effect, but also produce significant social and economic value.

　　After years of unremitting efforts, through the original innovation of catalyst, the optimization of reactor structure and the integrated innovation of the system, the ionic liquid team of Institute of Process Engineering of Chinese Academy of Sciences has developed a new route of synthesizing ethylene carbonate from CO2 and high-energy material ethylene oxide, and then producing dimethyl carbonate and ethylene glycol by alcoholysis respectively, forming a new all-atom utilization technology of mild conversion of CO2.

　　Just like turning the stone into gold, products produced by CO2 are all high-value "treasures", which have a wide range of application fields and considerable market prospects, but there are problems such as poor economic benefits after being used before.

　　Zhang Xiangping said that among diversified products, dimethyl carbonate is mainly used to synthesize important organic chemicals, which is known as the "new cornerstone" of green chemistry in the 21st century. It can be widely used in organic synthesis reactions such as carbonylation, methylation, methoxylation, carbonyl methylation, polycarbonates, etc. In recent years, with the rapid development of power lithium batteries, polycarbonates and other related industries, the demand for dimethyl carbonate continues to grow rapidly, and the demand in China is expected to be 4 million tons in 2020. Ethylene glycol is a raw material for the synthesis of polyester fiber and resin. China’s annual demand is more than 14 million tons, and its dependence on foreign countries is more than 60%.

　　According to the insiders, compared with the reaction route of direct conversion of CO2 into synthetic chemicals, this technology has obvious advantages such as mild reaction conditions, good atomic economy and broad industrialization prospects. The implementation of the project will help China seize the international commanding heights of CO2 utilization technology, solve and break through the bottleneck problem of clean and efficient utilization of coal in China, and open up a new path for high-value utilization of CO2, which has important strategic significance.
