摘　　要：主要介绍了北京冬奥会延庆赛区及周边水生态系统的保护与建设工作。北京冬奥会延庆赛区规划区内佛峪口河沟道及水库水质基本满足《地表水环境质量标准》(GB 3838—2002)中Ⅱ类标准,统计结果表明,佛峪口流域涉水植物共27科58种,两栖爬行动物共2目7科18种。根据工程建设活动对水生态系统的影响机理,从水文过程和水体水质恢复角度,有针对性地提出了水系连通、跌水和生态坡岸设计要点,河沟道水生植物配置方案,以及建立迁地保护基地等涉水动植物保护技术。通过采取上述技术和工程措施,能够保障北京冬奥会延庆赛区及周边水生态系统安全,可为同类雪上场馆项目水生态保护与建设工作提供技术借鉴。This paper mainly introduces the water ecological system protection and construction in the Beijing Olympic Winter Games Yanqing zone and the surrounding area. The water quality of Foyukou River and reservoir in the planning area basically accords with the class Ⅱ standard in the Environmental Quality Standards for Surface Water(GB 3838-2002). The statistical results show that there are 58 species of aquatic plants in 27 families and 18 species of amphibians and reptiles in 2 orders and 7 families in Foyukou Valley. According to the influence mechanism of engineering construction activities on water ecosystem, the key points of water system connectivity, falling water and ecological slope design, the configuration scheme of aquatic plants in river, and establishing the relocation protection base and related measures of protection techniques on water animal and plant are proposed based on the perspective of hydrological process and water quality recovery. The water ecological system safety of the Beijing Olympic Winter Games Yanqing zone and the surrounding area will be guaranteed by adopting the above-mentioned technical and engineering measures, and provide the technical reference of water ecological protection and construction for the similar snow venues construction.
