| 摘 要： | 以鄂州市西雷山地质灾害为研究对象,选取高差、坡度、工程地质岩组、斜坡结构类型、地质构造、人类工程活动等6个因子,采用基于GIS信息量模型进行易发性评价,最终分析结果在ArcGIS中成图显示,大大提高了地质灾害易发性分区评价效率,对今后开展类似的区域性地质灾害易发性评价提供参考。

| Abstract: | Taking the geological hazards in Xileishan of Ezhou City as the research object,this paper chooses six factors as elevation difference,slope gradient,engineering geological rock group,slope structure type,geological structure and human engineering activity,and evaluates the susceptibility of geological hazards by using GIS information quantity model.The final analysis show that the geological hazards are greatly improved by displaying images on ArcGIS.The efficiency of vulnerability zoning evaluation can be greatly improved,which will provide reference for similar regional geological hazard vulnerability evaluation in the future. |
