　　There are still 30 days to go before the opening of the Beijing 2022 Winter Olympics. The National Ski Jumping Center, known as "Snow Ruyi", is standing quietly on the top of the mountain in Zhangjiakou.

The two snow-covered tracks look like ice and snow waterfalls flying down from a distance.

　　The conditions of China's ice and snow sports are "strong ice" and "weak snow", and the corresponding stadium construction is also the same.

As the main stadium of the Beijing 2022 Winter Olympics snow events, Zhangjiakou competition area, how to build snow sports venues in a complex mountain environment, challenges not only the design and construction capabilities, but also a major consideration for how China should take into account ecological protection.

　　"We are doing our best to carry out ecological restoration." According to Wang Jingxian, deputy director of the second venue construction department of the Beijing Winter Olympics Organizing Committee and manager of the ancient poplar venue group facilities, the "Xue Ruyi" was selected in the valley and was It is considered to be a natural ski jumping venue, and only a small amount of cutting of the mountain can meet the requirements of the competition.

At the same time, the ancient poplar venues are also focusing on key ecological restoration of the cut mountains.

"This summer, the bare part of the mountain was already very green."

　　The National Biathlon Center, which faces the "Xue Ruyi", also maximizes the integration of artificial and natural environments.

According to Chen Guohui, National Biathlon Center Stadium and Infrastructure Manager of the Beijing Winter Olympics Organizing Committee Planning and Construction Department, the National Biathlon Center pays great attention to the "wild interest" of combining man and nature, both in its design and operation. beauty of.

　　"It can be seen that there is a very large tree directly above the shooting range. In order to protect this tree, we have fine-tuned the direction of the track and set up a special protection area." Chen Guohui said that the southern side of the National Biathlon Center is basically covered. It is a primitive forest. When there is a conflict between the track and the trees, the track will be fine-tuned as much as possible to keep the original trees.

　　"This is actually related to biathlon sports. We need to build a track that blends with nature." Chen Guohui explained that biathlon sports are related to people's hunting activities in winter. After years of evolution, this kind of " The feeling of shuttle in the "Linhaixueyuan" is still its unique charm.

　　In addition to the winding "forest" track, the National Biathlon Center has specially built 5 landscape lakes, which not only enhance the overall level and beauty of the stadium, but also form the general outline of the track.

"We originally wanted to design a big lake, but it would greatly damage the original landform, so we changed the design plan to build 5 small lakes." Chen Guohui said that this move can not only protect the track from being corroded by underground springs, but also the groundwater. It will gather in the landscape lake for snow making and realize recycling.

　　"The National Cross-Country Ski Center is the closest competition venue to the original ecology." According to Li Zhenlong, the venue and infrastructure manager of the National Cross-Country Ski Center, the technical building of the National Cross-Country Ski Center is the smallest of the ancient poplar venues.

As Zhang Li, dean of the School of Architecture of Tsinghua University and the chief design officer of Zhangjiakou for the Beijing 2022 Winter Olympics, said, the National Cross-Country Ski Center is to have the smallest ecological footprint and leave the largest environment for natural leisure activities after the game.

　　Different from the newly-built ancient poplar venues, Yunding Ski Park is the only snow competition venue for the Beijing 2022 Winter Olympics that relies on the existing ski resort to be rebuilt.

　　"The rebuilding of the track itself is the greatest protection of the ecological environment." Wang Baoqi, vice president of Secret Garden Genting Paradise, said that the Yunding Ski Park fully considers the characteristics of mountain topography. 4 of the 6 Winter Olympics tracks are converted from original ski tracks. During the reconstruction process, the earth-rock excavation and filling balance was basically realized, and the surrounding ecology was protected to the greatest extent.

　　From catching up to striving to lead, China is becoming a model for building snow sports venues in a complex mountain environment.

The 2022 Winter Olympics in Beijing will coincide with the Chinese Lunar New Year. I hope that the strong "New Year" will pass on the oriental culture to the world, and I also look forward to the wonderful "Winter Olympic Town" decorated with winter snow.
