Abstract

After Wenchuan Earthquake on May 12, 2008, various geological hazards happened frequently in Chongzhou city, Sichuan.This paper analyzes factors inducing hazards by weighted comprehensive evaluation (WCE) and analytic hierarchy process (AHP), and builds the geological hazards assessment model.On the basis, the map of geological hazards lability zoning is drew. The study shows that geological hazards in Chongzhou city are mainly landslide, collapse,unstable slope and debris flow. According the risk degree value of geological hazards every field, Chongzhou city is regionalized to high, middle, low and none risk area of geological hazards. The results display that almost all geological hazards distribute in northwest mountain area of this city where is key area of geological hazards prevention in future.
