摘　　要：文中研究的斜坡类地质灾害易发性评价以坡度、坡形、起伏度、工程地质岩组、地质构造、植被覆盖和土地利用类型作为评价因子,以364处地质灾害(隐患)点作为样本,采用GIS软件空间分析功能和信息量模型法,计算各因子信息量,并按一定权重叠加得出各栅格单元的总信息量,结合野外调查实际情况,将研究区地质灾害划分为高、中、低和非易发区。该评价结果将为研究区地质灾害防治提供重要指导。This evaluation of slope geological disaster susceptibility takes slope,slope shape,topographic relief,engineering geological rock group,geological structure,vegetation cover and land use type as evaluation factors,and takes 364 geological disaster(hidden danger)points as samples.GIS software spatial analysis function and information model method are used to calculate the information information of each factor.According to the actual situation of field investigation,the geological hazards in the study area are divided into high-prone area,middleprone areas,low-prone areas and non-prone areas.The above evaluation results will provide important guidance for the prevention and control of geological disasters in the study area.
