Abstract

Abstract

The Xuefeng Mountain area in Hunan Province is one of the regions seriously suffering from the rainfall-induced landslide disasters, which have a severe impact on social and economic development and cause heavy damage to people's lives and property. Five key geological factors including slope aspect, elevation, engineering rock assemblage, slope type and gradient that affect landslide are selected to solve the problem of ranking assignment of each factor index and weight of factor superposition in evaluation through the combination of certainty factor(CF) and analytic hierarchy process(AHP). Based on the given factor weights, the weights and assignments are multiplied and then added to calculate the comprehensive sensitivity values of rainfall-induced landslide in the study area. The sensitive areas are then divided according to the sensitivity indexes.
- rainfall-induced landslide /
- impact factor /
- sensitivity zoning /
