| 摘 要： | 在仙游县地质灾害详细调查成果基础上,综合考虑该县地质灾害的主要控制因素,选取工程活动、地灾发育度、地形地貌、岩土体类型、大气降雨和植被覆盖率6个影响因素,采用层次分析法确定各因子权重,并利用MapGIS空间分析功能,绘制出该县的地质灾害易发性分区图,为该县地质灾害防治提供依据。

| Abstract: | Based on the detailed survey results of geological disasters in Xianyou County,considering the main controlling factors of geological disasters in the county,six factors were selected,which were engineering activities,ground disaster development degrees,topography and landform,rock and soil body types,atmospheric rainfall,and vegetation coverage.The analytic hierarchy process was used to determine the weight of each factor,and the spatial analysis function of MapGIS was used to draw the zoning map of geological disaster susceptibility of the county,which provided a basis for geological disaster prevention of the county. |
