Ecological restoration is about to be completed, Yanqing competition area becomes a green development “Beijing sample”_General Administration of Sports

The highest altitude is 2198 meters, the maximum slope exceeds 70 degrees, the lowest temperature is minus 30 degrees Celsius, the topsoil is stripped of 81,000 cubic meters, and the ecological restoration area is 2.14 million square meters… As the project with the longest construction period of the 2022 Beijing Winter Olympics, Yanqing competition area The ecological restoration work lasted 6 years and will be fully completed by the end of this month. After a rain on June 23, the four Olympic venues in the Yanqing competition area unfolded a beautiful picture on the vibrant Xiaohaituo Mountain.

According to Yu Dequan, deputy director of the Beijing Municipal Major Projects Office, highlighting the “green Olympics”, combining the construction of Olympic venues with the promotion of ecological civilization, and striving to make sports venues and municipal supporting facilities harmoniously blend with the natural landscape of Xiaohaituo Mountain. It is an important principle for the construction of venues in the Yanqing competition area. The highest altitude in the competition area is 2198 meters, and the construction conditions are difficult. The ecological restoration work is as difficult as the new stadium project. The builders overcome various difficulties, from the ecological investigation at the beginning of the construction to the formulation of protection standards; from the construction while protecting, and then to the ecological restoration project, the Yanqing competition area takes 7 snow roads and the slopes around the municipal roads as the main restoration areas, and the total is completed. The repaired area is 2.14 million square meters.

According to Liu Lifeng, director of the Yanqing Stadium Construction Division of the Beijing Municipal Major Projects Office, in 2016, before the “first shovel soil” was launched in the Yanqing competition area, relevant forestry, water, soil, and ecological experts carried out very forward-looking work for the ecosystem. The protection and restoration of the Olympic Games provide a basis for scientific decision-making, and on this basis, the possible ecological environmental interference caused by the construction of Olympic facilities is evaluated, and the possible negative impacts due to the construction of stadiums and infrastructure are minimized.

Up to now, there are a total of 313 trees under in-situ protection in the competition area, 24272 trees have been transplanted ex-situ, and nearly 300 acres of ex-situ protection bases have been built, with a survival rate of about 99%; 11027 shrubs and grasses have been transplanted close to the ground, and these plants are currently owned by professional gardening units Careful maintenance.

Mountain topsoil is a precious natural resource that has been formed after thousands of years. According to Zhao Ruiyong, the landscape engineer of Beijing Beijing Beijing Jingao Construction Co., Ltd., in order to quickly restore the natural vegetation in the Yanqing competition area, they have carried out “all manual” recovery of the topsoil stripped during the construction process. After one year, the Yanqing competition area stripped a total of 81,000 cubic meters of topsoil. All of these topsoil has been reused with the ecological restoration work, which has become a key factor in the rapid restoration of the original ecology of Haituo Mountain.

The National Alpine Ski Center has built 7 ski trails, accounting for one-half of the total repaired area. At present, the ecological restoration of all 7 ski trails has been completed. The green lawn covers the long ski trails. Looking from the air, the horizontal drainage ditches are like terraced ridges, so that the ski trails are scattered and effectively restored. The natural landscape in the ski area enhances the stability of the ecosystem in the Yanqing competition area.

Yu Dequan said that the ecological restoration work in Yanqing competition area will enter the stage of beautification, optimization and refinement next. The ecological restoration work in the Yanqing competition area is a vivid practice of practicing the concept of green Olympics. The Yanqing competition area will be built into a treasured land of “flowers in spring, cool breeze in summer, drunken mountains in autumn, and snow in winter”, making it worthwhile Inheriting high-quality assets that benefit the people, the Yanqing competition area has become a “Beijing sample” for green development.
