摘要
文章根据赣州市赣县区1/50000地质灾害风险调查与区划项目资料和实地调查,以赣县区为研究区,利用地形坡度、斜坡结构、地貌类型、工程地质岩组、土层厚度、灾点密度6个评价指标和GIS平台,获取各评价单元的地质灾害综合危害性指数,将赣县区地质灾害易发程度划分为高、中、低易发区和非易发区4个等级。通过分区评价,为地方政府防灾减灾提供科学依据。
According to the 1/50000 geological disaster risk survey and zoning project data and field survey in Ganxian District of Ganzhou City,this paper takes Ganxian District as the research area,and uses six evaluation indexes of terrain slope,slope structure,landform type,engineering geological rock group,soil layer thickness and disaster point density and GIS platform to obtain the comprehensive hazard index of geological disasters in each evaluation unit.The susceptibility of geological disasters in Ganxian District is divided into four grades:high,medium,low and nonsusceptible areas.Through zoning evaluation,it provides a scientific basis for the disaster prevention and mitigation of local government.
