Abstract

The western region of Chongqing seriously suffers from landslides. This paper evaluate the landslide hazard using GIS (Geographic Information System) technology and information value model and selecting seven influential factors including slope, aspect, elevation, rain, river, road and geological structure. The results show that the southern region of the study area are the most hazardous region. From the evaluation results, 20.6% of the total area suffers from high landslide risk and 13.1% suffers from very high risk, which is of important practical and immediate significance to the landslide prevention and reduction in the area. The evaluation result is basically coincident with the reality. The study further demonstrates that the information value model combined with geographical information system can quickly and effectively evaluate the spatial distribution and risk of the landslide hazard.
