On the second anniversary of the opening of Beijing Zhangjiakou high-speed railway, Beijing Tianjin Hebei on the track ran out of "acceleration"; "Below zero economy" has become a hot word, and the ice and snow industry is in full swing; The ecological environment continues to improve, and green is becoming a beautiful background for coordinated development Guided by the Olympic concept of "green, sharing, openness and integrity", Beijing, Tianjin and Hebei have conducted in-depth cooperation in transportation, industry, ecology and other fields to share Winter Olympic opportunities. The Winter Olympic Games are drawing the finishing touch of the game of coordinated development of Beijing, Tianjin and Hebei. (Zhangjiakou Olympic Village) Evidence of Beijing, Tianjin and Hebei traffic changes in the past century On December 30, 2021, the Beijing Zhangjiakou high speed railway ushered in the second anniversary of its opening. With the Winter Olympics approaching, it has become a choice for more and more people to ski and watch the Winter Olympics on the high-speed railway. Two years ago, the world's first intelligent high-speed railway with a speed of 350 kilometers per hour - Beijing Zhangjiakou high-speed railway was officially opened to traffic. Zhangjiakou, Hebei Province officially entered the "one hour life circle" of Beijing, Tianjin and Hebei. The Beijing Zhangjiakou high-speed railway is 174km long, starting from Beijing North railway station, all the way north, passing through Juyongguan Great Wall, Shuiguan Great Wall, Badaling Great Wall and other places, and arriving in Zhangjiakou, another host of the 2022 Beijing Winter Olympic Games. From Beijing Zhangjiakou Railway to Beijing Zhangjiakou high-speed railway, the difference between a word and a hundred years, witnessing China's railway from "backward" to "leading". Through the vicissitudes of a century, leading to a better future. "In the past, it took more than four hours to drive from Beijing to Chongli, and there were frequent traffic jams. Now it takes almost an hour by high-speed rail." Liu Yun, who works in Beijing, is a keen skier. It has become her best choice to go skiing in Chongli by high-speed rail on holidays. In the two years since the opening of Beijing Zhangjiakou high-speed railway, more than 13.8 million passengers have been sent, with an average daily of 19000. Nearly 40000 pairs of trains have been operated in total, increasing from 36 pairs of trains per day originally planned to 65 pairs per day now. The Beijing Winter Olympics includes three competition areas: Beijing, Yanqing and Zhangjiakou. In order to realize the seamless connection of the three competition areas, the accelerated construction of Beijing Zhangjiakou transportation network will not only ensure the needs of the Winter Olympic Games at a high level, but also further promote the construction of an interconnected comprehensive transportation network between Beijing, Tianjin and Hebei. At the end of 2016, the Hebei section of Yanqing Chongli (Yanqing Chongli) Expressway was started, which sounded the rally call for Hebei transportation to fully carry out the transportation support work in preparation for the Winter Olympic Games. On January 23, 2020, Yanchong expressway was completed and opened to traffic, opening up a convenient channel from Beijing to the competition area of Chongli Prince city in Zhangjiakou, providing convenient transportation for people from Beijing and Tianjin to Chongli and people from Northwest China to Beijing. Today, a comprehensive transportation network for the Winter Olympic Games dominated by railways and highways and supplemented by aviation and a public transport oriented transportation service guarantee system for the Winter Olympic Games have been fully formed. Transportation is the "pioneer" of coordinated development. Connectivity is a vivid epitome of regional coordination promoted by the Beijing Winter Olympic Games. The nearly seven years since Beijing joined hands with Zhangjiakou in preparing for the Beijing Winter Olympics are also a time for the coordinated development of Beijing, Tianjin and Hebei. In terms of rail transit, "Beijing, Tianjin and Hebei on the track" has initially taken shape and continues to play a role. The construction of Regional National Trunk Railways has been continuously improved. With Beijing and Tianjin as the core hubs, the national high-speed railway network connecting cities in Hebei Province has been basically completed. The adjacent cities have basically achieved 1.5-hour railway access, and the "1-hour traffic circle" has been formed in Jingxiong, Tianjin and Baotou. In terms of highway transportation network, the construction task of national expressway network has been basically completed, and the "single center, radial" road network structure has been effectively improved. By the end of 2020, the total mileage of expressways in Beijing, Tianjin and Hebei reached 10307 km, an increase of 29.2% over 2014. At the same time, by the end of 2020, the three provinces and cities had opened 32 sections of "access roads to be connected" and "bottleneck roads", with a total of 2005 kilometers, and all the radiation lines in the capital of the national high tech network had been opened. In terms of aviation hub, the layout of the Beijing Tianjin Hebei airport group of "double core, two wings and multi nodes" has been completed, nine planned airports in Beijing, Tianjin and Hebei, such as Beijing Daxing International Airport, have been put into use, and the construction of the airport economic zone of Daxing International Airport jointly built and managed by Beijing and Hebei has also been fully started. At the same time, the landside traffic support system of the airport has been continuously improved, and the high-speed road network with the airport as an important node has been further optimized. The four major airports of Beijing, Tianjin and Shijiazhuang have opened urban rail transit express lines, and a comprehensive transportation system connecting the hub airport and rail transit is constantly taking shape. "Below zero economy" is in full swing It was a cold winter, but Zhangjiakou, as one of the venues of the 2022 Beijing Winter Olympic Games, ushered in the hottest time of the year. In addition to the extensive development of ice and snow sports and tourism, Zhangjiakou is vigorously developing the ice and snow equipment industry by hosting the Winter Olympic Games. The "below zero economy" has become a hot word in Zhangjiakou. At present, Zhangjiakou plans to build snow and ice equipment R & D and manufacturing clusters such as snow and ice equipment Industrial Park of high tech Zone and Xuanhua snow and ice Industrial Park. As of December 15, 2021, the city has signed 97 ice and snow industry projects, with a total investment of 37.328 billion yuan, 79 landing projects and 41 projects put into operation. Mei Xiaochun, deputy secretary and executive deputy director of the Party Working Committee of Zhangjiakou high tech Zone, said that the Industrial Park focuses on the development of personal light equipment such as ski clothes, skis and ski shoes, and heavy equipment such as snow maker, snow roller and cableway. At present, the whole industrial chain layout covering from individual to venue, the combination of light and heavy equipment, R & D, manufacturing and sales services, sports experience and exhibition has been preliminarily realized. "Half city grape and half city steel", as the industrial core area of Zhangjiakou, Xuanhua district has a strong industrial foundation and sufficient industrial workers. At present, Xuanhua ice and snow Industrial Park, with a planned area of 3200 mu, is committed to building a national ice and snow equipment industry cluster, has successively set up a national ice and snow equipment testing and inspection center, and effectively build a world-class ice and snow equipment R & D and manufacturing base. Zhangjiakou Xuanhua Hongda Metallurgical Machinery Co., Ltd., which settled in Xuanhua ice and snow industrial park at the beginning of 2020, is an enterprise mainly producing off-hook cableway up and down station equipment for scenic spots. "Before, the market demand for detachable Cableways produced by enterprises was small. After the successful bid for the Winter Olympics, it will bring development opportunities to enterprises." Zhang Changsheng, general manager of Zhangjiakou Xuanhua Hongda Metallurgical Machinery Co., Ltd. It is understood that the company chose to settle in the ice and snow Industrial Park in Xuanhua district because the government has given more preferential subsidies to the enterprises in the park and opened a "green channel" for project approval. In the past three years, the enterprise sales have increased from 30 million yuan to 100 million yuan, and the total sales this year is expected to reach 120 million yuan. In recent years, Xuanhua district has seized the opportunities for the coordinated development of Beijing, Tianjin and Hebei and the preparation of the Winter Olympic Games. Taking the "ice and snow economy" as a breakthrough in industrial transformation and upgrading, Xuanhua district has continuously increased investment attraction, built an ice and snow Industrial Park in Xuanhua District, made a full "ice and snow +" article, extended and expanded the ice and snow industrial chain, cabin skiing, Kono engineering plastics A number of well-known enterprises such as HTC metallurgical machinery have successively put into operation, and the ice and snow equipment manufacturing industry shows a good development momentum. At present, Zhangjiakou is building the Beijing Zhangjiakou sports cultural tourism industrial belt into an Olympic economic growth belt, a cultural industry agglomeration belt and a regional cooperation demonstration belt. Chongli has built seven ski resorts including Yunding, Taiwu and Wanlong, becoming the largest ski gathering area in China. By the end of 2020, Chongli ice and snow tourist resort will be ranked as a national tourist resort. Let ice and snow sports enter thousands of households, poor counties eat "ice and snow rice", and "cold resources" release "great heat". Hebei ice and snow industry is ushering in unprecedented development opportunities and gradually embarking on the road of high-quality development. Along the way, the concept of "green, sharing, openness and integrity" has led Beijing and Hebei to carry out extensive and in-depth cooperation in many fields and made a new acceleration. Taking public services as an example, the Third Hospital of Peking University took over Zhangjiakou Chongli District People's Hospital and became the designated hospital for medical security in Zhangjiakou competition area of Winter Olympic Games and winter Paralympic Games. The signing of Beijing Hebei medical security cooperation agreement for the Winter Olympics and the implementation of many medical cooperation projects effectively integrate high-quality medical and health resources in Beijing, Tianjin and Hebei, and orderly promote the medical security work for the Winter Olympics. Hebei has accelerated its development in connecting and serving Beijing and Tianjin. Solid results have been achieved in the "three major events" such as the coordinated development of Beijing, Tianjin and Hebei, the planning and construction of xiong'an new area and the preparation of the Beijing Winter Olympic Games. Up to now, Hebei Province has undertaken nearly 40000 enterprises and units transferred from Beijing and Tianjin, involving an investment of 1.28 trillion yuan. Xiong'an new area has entered a new stage of undertaking the simultaneous promotion of Beijing's non capital function relief and large-scale construction, and the "city of the future" has sprung up. Preparations for the Beijing Winter Olympic Games have been basically completed and a series of test competitions have been successfully held. All 76 key projects were completed ahead of schedule, and the supporting facilities and service guarantee were carefully done, which was fully affirmed by the IOC. "Green Olympics" promotes the green transformation of Beijing, Tianjin and Hebei "Lighting the lights of Beijing with the wind of Zhangbei" is a poetic slogan particularly eye-catching at the site of Zhangbei flexible DC project. In June 2020, the pilot demonstration project of Zhangbei flexible DC power grid was officially put into operation, which can deliver about 14.1 billion degrees of clean energy to Beijing every year. In addition, the project will also provide guarantee for the "green operation" of Winter Olympic venues and help Beijing Winter Olympic venues realize 100% clean energy power supply for the first time in Olympic history. "Green Olympics" is China's commitment to the world. During the 2022 Beijing Winter Olympics, 655 hydrogen fuel vehicles will be invested in Zhangjiakou competition area to provide transportation and logistics support services for the events. Hydrogen fuel vehicle is to add hydrogen to the vehicle and "generate electricity on site" through the chemical reaction of hydrogen and oxygen ions. Its fuel comes from hydrogen and is discharged from water, which is green and pollution-free. At the same time, it also has the characteristics of fast energy supply and less time. In Zhangjiakou City, 444 hydrogen fuel cell buses have been put into operation, covering 9 bus lines in the city. Zhangjiakou currently has 2 hydrogen production plants and 8 hydrogen refueling stations, which can meet the guarantee requirements of hydrogen fuel vehicles for the Winter Olympic Games. It is reported that each hydrogen fuel bus running 10000 kilometers can reduce carbon dioxide by about 11.8 tons. During the test competition of the Winter Olympic Games, the hydrogen bus ran smoothly at more than minus 20 degrees Celsius, and its stability and safety were verified. As a renewable energy demonstration area, in recent years, Zhangjiakou has been accelerating the construction of an industrial system for comprehensive utilization of hydrogen energy, and has initially formed a whole industrial chain of hydrogen production, hydrogenation, hydrogen storage, hydrogen energy industrial equipment manufacturing, fuel cell core parts manufacturing, hydrogen energy vehicle manufacturing, etc. "hydrogen energy Zhangjiakou" has become a new business card for urban development. "A wind blows once a year, from spring to winter". As the host of the snow project of the Beijing Winter Olympic Games, Zhangjiakou undertakes the important task of water storage source and sand blocking source. In the past, due to the destruction of vegetation, some areas became the source of dust storms. With the improvement of sandstorm sources in Beijing and Tianjin and the promotion of the construction of three North shelterbelts, the scene of "yellow sand all over the sky" has disappeared. In Chongli, a small Winter Olympic City under the jurisdiction of Zhangjiakou, there are ups and downs of forests in the mountains. In recent years, there have been many problems, such as planting trees and planting trees. Yang Jianzhong, chief engineer of Chongli District Forestry and grass Bureau, said that the forest coverage in the core area of the Winter Olympic Games has exceeded 80%, becoming a ski resort and outdoor sports paradise. We will resolutely build an ecological barrier for Beijing, Tianjin and Hebei. Hebei Province takes the construction of "two districts" as the fundamental goal, highlights "two mountains, two wings, three rings and four edges", and scientifically carries out large-scale land greening. During the 13th Five Year Plan period, a total of 39.54 million mu of forest was built, and 2.72 million mu of "three modernizations" grassland was restored and managed. Zhangcheng area has become the area with the best air quality in North China and completed the protection of Beijing and Tianjin
