By using the landslide risk evaluating model and the advantages of GIS technology in image processing and space analysis,the relative landslide hazard and risk evaluating system of the new county site of Badong is built up.The system is mainly consisted of four subsystems:Information management subsystem,hazard assessment subsystem,vulnerability evaluation subsystem and risk prediction subsystem.In the system,landslide hazard assessment,vulnerability evaluation,risk predictions are carried out automatically based on irregular units.At last the landslide hazard and risk map of the study area is compiled.During the whole procedure,Matter-Element Model,Artificial Neural Network,and Information Model are used as assessment models.This system provides an effective way for the landslide hazard information management and risk prediction of each district in the Reservoir of Three Gorge Project.The result of the assessment can be a gist and ensure for the land planning and the emigration project in Badong.
