| 摘 要： | 通过调查,认为费县地质灾害主要为滑坡、崩塌、泥石流,其发育与地形地貌、地层岩性、地质构造和人类工程活动、大气降水关系密切。依据地质灾害发育现状和规律、致灾因子,利用MapGIS空间分析功能和Microsoft Excel数据计算功能对其进行叠加,获得各评价单元的地质灾害综合危险性指数,将费县地质灾害易发程度分为高易发区、中易发区、低易发区、不易发区4个区,并进行了分区评价。为当地国土资源部门的地质灾害防治工作提供科学的理论依据。

| Abstract: | Through field investigation, andslides, collapses and mudslides are considered as main geological disasters in Feixian county. The developments of geological disasters are closely related to topography, lithology, geological structures, human engineering activities and the rainfall. Based on present condition of geological hazards and laws and disastercausing factors, the author acquires each evaluated unit of geological disaster risk index by superimposition with the spatial analysis function of MapGIS and Microsoft Excel data calculated function. According to the easyhappening degree of geological hazards, Feixian county has been divided into high easyhappening area, medium easyhappening area, low easyhappening area, not prone area and comments on each area. It will provide scientific basis for preventing and controlling geological hazards by local departments of land resources. |
