摘要
The new county-site town of Badong was selected for research on hazard zonation in this paper and the characteristics of landslides’ development were described. Based on the platform of MAPGIS software, the town is divided into 223 irregular units according to the direction and gradient of the slope. The evaluation index system was established by the Analytic Hierarchy Process and the integrated index affected by multi-factor was calculated by the superposition of every factors’ index map based on the information value mode,the slope’s stability was predicted quantitatively and the hazard zonation was compiled.
