【摘 要】本文结合研究区的野外地质调查资料，采用地质灾害易发性评价综合指数法，选取6项评价指标，利用MAPGIS软件的空间分析功能对研究区地质灾害程度进行计算评价和分级区划，依据危害程度将其划分为高易发、中易发、低易发和不易发四个区。结果显示地质灾害高易发区分布在公路交通沿线，采石场以及人类工程活动较集中地区，本次评价结果可为地质灾害的防治规划提供依据。

Abstract:Based on field geological survey data, we select six evaluation indexes using the comprehensive index of geological disaster evaluation method to calculate and evaluate;Then spatial analysis function of MAPGIS software was used in calculating the geological hazard index. According to the degree of damage, it is divided into high moderate low and non-susceptibility areas. The results showed that the high incidence areas were distributed along the highway, quarries,and human engineering activities. At last the evaluation results can provide the basis for the prevention and control of geological disasters.
