北京冬奥会延庆赛区亚高山草甸保护与恢复技术研究

Research on the Conservation and Restoration Techniques of Subalpine Meadows in the Yanqing Competition Area of the Beijing Winter Olympics

北京冬奥会延庆赛区生长着宝贵的亚高山草甸资源,在冬奥会相关赛事的修建过程中,为了充分保护该地区的草甸资源,结合亚高山草甸保护的难题,综合对本地草甸类型区进行划分,制定了有效的亚高山草甸保护和恢复措施。首先将草甸区域划分为保护区和影响区,其次对施工影响区内立地条件适合的区域进行草甸剥离,根据“就近移植”的原则开展回铺施工。随后,开展草皮的收集-移植-养护工作,实现了回铺草甸和原生草甸融为一体的生态效果。本研究所提出的综合保护方案能够科学合理地实现草甸的移植回铺工艺,为我国亚高山地区工程的绿色修建与生态修复提供技术支持。

The Yanqing competition area of the Beijing Winter Olympics is blessed with valuable subalpine meadow resources,in order to fully protect these meadows during the construction process of the Winter Olympics related events and address the challenges of subalpine meadow conservation,a comprehensive division of the local meadow types was carried out and effective measures for protection and restoration were formulated.Firstly,divide the meadow area was into protected and affected,secondly,carry out grassland stripping in areas with suitable site conditions within the construction impact area,followed by the principle of “transplantation nearby” to establish new meadows.Subsequently,the process involved the collection,transplantation,and maintenance of turf,resulting in the successful integration of reestablished meadows with the native meadows.The comprehensive protection plan and proposed by this research institute can scientifically and reasonably achieve the transplantation and reestablishment process of grasslands,to provide technical support for the green construction and ecological restoration in China's subalpine regions.
