摘　　要：影响地质灾害发育的主要因素有地形地貌、基础地质、人类工程活动以及地表覆盖等。通过对已有资料的分析处理,采用信息量发进行易发性分区,叠加降雨信息进行危险性分区,继而叠加易损性进行地质灾害风险评价。The main factors affecting the development of geological disasters are topography,basic geology,human engineering activities and surface coverage.Through the analysis and processing of the existing data,the information quantity is used for the susceptibility zoning,and the rainfall information is superimposed for the risk zoning,and then the vulnerability is superimposed for the risk assessment of geological disasters.

关 键 词：地质灾害 易发性 危险性 风险评价
