北京市门头沟区地质灾害危险性评价研究

摘要

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。%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.
