摘　　要：以海南省万宁市为研究对象,选取高程、坡度、岩组、距断层距离、地表水与地下水、植被等6个因素为评价指标,建立信息量模型对各评价指标进行分析,依托ArcGIS平台单元统计功能,将万宁市按地质灾害易发性划分为高易发区、中易发区、低易发区和非易发区,分别占总面积的5.44%、34.02%、53.95%、6.59%。Taking Wanning City of Hainan Province as the research object,six factors such as elevation,slope,rock group,distance from fault,surface water and groundwater,vegetation were selected as evaluation indexes,and information model was established to analyze each evaluation index.Based on the unit statistical function of ArcGIS platform,Wanning City was divided into high-prone,medium-prone,low-prone and non-prone areas according to geological disaster susceptibility,accounting for 5.44%,34.02%,53.95%and 6.59%of the total area,respectively.
