| Abstract: | 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. |
