摘要
以密云库区为研究对象,利用生态环境现状调查资料和相关研究成果,通过生态服务价值、地质灾害、植被覆盖指数、坡度及土地覆被类型5个指标对密云库区生态环境敏感性进行了综合评价,识别出主要生态敏感区域。结果表明:生态服务价值变化对生态环境最为敏感,地质灾害因子次之;生态敏感性极高的区域主要为石城镇大部分地区、高岭镇西北部及北庄东南部和西南地区,不敏感区包括十里堡、巨各庄、大城子中部等地区。
Taking Miyun Reservoir as the research object, 5 sensitive indices for eeo-cnvironment were selected based on the information of coo-environmental investment and previous studies, such as ecological service value, geology disaster, vegetation-cover index, slope, land-use types. A comprehensive evaluation was made on the eco-environmental sensitivity of Miyun Reservoir. The main ecological sensitivity areas were distinguished. The results of the research showed that the most sensitive factor of ecological environment was ecological service value, followed by geological disaster factors. The most sensitive areas are most areas of Shicheng Town, northwest areas of Gaoling Town, southeast and southwest areas of Beizhuang. In addition, some towns, such as Shilibao, Jugezhuang and middle Dachengzi were non-sensitivity areas.
