| 摘 要： | 地质灾害易发程度评价是在区域地质灾害危险性评价中一项主要任务，其表征某一区域地质灾害发生的可能性概率的一个主要指标。利用层次分析法可以定量或半定量的评价区域地质灾害的易发程度．效果比较理想。以成县为例确定地质灾害评价目标层、准则层、指标层，将影响地质灾害的各类因子进行分级，权重分配，利用mapgis平台对工作区进行矢量网格化、空间属性叠加分析、生成等值线图，实现地质灾害易发程度分区的目的。

| Abstract: | The geohazards susceptibility is a main critical to decribe possibility of geohazards occurrence. Geohazards susceptibility evaluation is one of main tasks on the evaluation of regional geohazards risk. The quantitative or semi-quantitative evaluation on geohazard susceptibility using Analytical Hierarchy Process （AHP） was effective. Taking Chengxian County as an example, the paper introduced how to combine AHP with MapGIS for geohazards susceptibility evaluation. |
