摘要
应用法国SOPT-5图像,以ERDASIMAGE软件为平台对研究区土地利用进行监督分类,分析研究区土地利用各个类型与地质灾害的相关性,利用层次分析法确定影响灾害指标及权重。得出居住用地区是地质灾害高易发区,对应了地质灾害易发分区图。
Taking ERDAS-IMAGE software as a platform,the author classified the SPOT 5 images in some county using supervised classification approach,analyzed the relevancy of various types of land use and geological hazard in study area,and at last determined the impact of disaster indicators and weight by layer analysis method.According to the result of the analysis,the author found that living zone in the region is prone areas of high geological hazards and the same to geological disaster-prone area maps.The study provided the scientific basis for the planning of land resources and the prevention of geological hazards.
