Why can Beijing win the title of "Double Olympic City"?

What are the geographical factors and advantages behind it?

suitable climate

  Unlike the Summer Olympics, the Winter Olympics have strict requirements on the climate.

Looking at the venues of the previous Winter Olympics, we found that these cities are basically between 40 degrees north latitude and 70 degrees north latitude. The holding time is generally in February, and the temperature is -17℃-10℃, which is the ideal temperature for the Winter Olympics.

  Beijing's ability to become a "Double Olympic City" that hosts both the Summer Olympics and the Winter Olympics is determined by Beijing's climatic characteristics.

  The geographical latitude of Beijing is about 40 degrees north latitude, which is a typical temperate monsoon climate zone. The climate is characterized by high temperature and rainy summer, cold and dry winter, and four distinct seasons.

Therefore, from the perspective of the Olympic Games, both summer and winter events are suitable to be held in Beijing's winter and summer.

Terrain advantage

  The snow sports of the Winter Olympics themselves have almost strict requirements on natural and geographical conditions. Among them, alpine skiing, sledding, snowmobiles and other projects require a large gap between the venues.

For example, the distance of the alpine skiing track is generally about 3,000 meters, but it requires a field drop of 800 to 1,000 meters, so such events are often held in the mountains.

The picture shows a schematic drawing based on the venue of the 23rd Winter Olympics.

  The Yanqing competition area is located in the Xiaohaituo mountainous area of ​​Yanqing District in the northwest of Beijing. Considering the favorable terrain conditions of Xiaohaituo, Yanqing, it independently undertakes the alpine skiing event of this Winter Olympics.

  The alpine skiing competition venue in Beijing Yanqing Division has a total of 7 ski tracks. Relying on the planning and construction of the natural mountain shape of Xiaohaituo Mountain, the total length reaches 21 kilometers, with a drop of about 900 meters and a slope length of more than 3,000 meters. The natural "rock" is the main element of the track. This feature and the difficulty of the track itself will establish the status of the Yanqing Haituo Mountain downhill track in the world's alpine tracks.

  In addition to the Beijing competition area and the Yanqing competition area, the Zhangjiakou competition area, one of the three major competition areas of the Beijing Winter Olympics, has undertaken most of the snow sports competitions. ”, Ice and Snow Town echoed each other and witnessed this ice and snow feast together.

  Suitable climatic conditions and natural geographical advantages make Beijing and surrounding cities a "natural ice and snow field", which is open to witnessing and looking forward to the players to show their talents.
