摘要
基于中山市1∶5万地质灾害详细调查项目,利用MAPGIS的空间分析功能,采用地质灾害综合危险性指数法,定量划分了中山市地质灾害易发区。分区结果为中山市后续完善群测群防体系、地质灾害防治等提供了技术支撑。
Based on the detailed data of 1∶50,000 geological disaster survey in Zhongshan City,this paper quantitatively divided the geological disasters prone areas of Zhongshan city by the spatial analysis function of MAPGIS and the comprehensive hazard index method of geological disasters,which provided technical support for the improvement of group survey and prevention system,and technical support for geological disasters prevention and control in Zhongshan city.
