北京市门头沟区境内98.5%为山区,地形地质条件复杂,地质灾害较发育,截至2014年3月,在门头沟区调查确定的地质灾害隐患点共644处。采用层次分析综合指数法,对门头沟区地质灾害易发性进行综合评价,划分了地质灾害高易发区、中易发区、低易发区、不易发区4个等级。
北京市門頭溝區境內98.5%為山區,地形地質條件複雜,地質災害較髮育,截至2014年3月,在門頭溝區調查確定的地質災害隱患點共644處。採用層次分析綜閤指數法,對門頭溝區地質災害易髮性進行綜閤評價,劃分瞭地質災害高易髮區、中易髮區、低易髮區、不易髮區4箇等級。

The mountainous area accounts for 98.5%in the total area of Mentougou District of Beijing. The topography condition is complex and the geological disasters are well developed. By March 2014, we have investigated about 644 geological disaster points in the Mentougou District. The paper comprehensive evaluates the geological disaster-prone using the AHP process, and divides the studying areas into high-prone areas, medium-prone areas, low-prone areas, no-prone areas in terms of geological disasters.
