摘要
The distribution,probability and damage of landslide are three principal factors of the integrative assessment for regional landslide risk.The distribution and influence range of landslides are assessed on the basis of landslide risk zonation,and the probability of landslide is calculated.The extent of damage is estimated by the percentage of damage region comparing with study area.The landslide risk integrative assessment model is established by overlaying the three principal factors.This model was applied in the Miyi County,Panzhihua City,Sichuan Province,the risk degree of the study area is lower-middle level which is consistent with the actual situation after the risk assessment.
