- Abstract:
- The Lijiang-Xiaojinhe fault has intense Holocene activity and frequent earthquakes; the geological disaster,landslide along the fault zone is incredibly developed.In this paper,places 10 km away from both sides of the middle and south sections of the fault zone are taken as the study areas.According to the geological and geographical environment and landslide development characteristics,10 factors are selected.They are topography(elevation,slope,aspect),lithology,distance of faults,roads,rivers,average annual precipitation,land use type,and peak ground acceleration.The weight of evidence method is used to establish the landslide vulnerability evaluation model to evaluate landslide vulnerability of the Lijiang-Xiaojinhe fault.Based on the natural breakpoints' method,landslide susceptibility is labled as “high”, “medium”, “low” and “none”. The assessed AUC-value is 0.809.The landslide in the study area is mainly affected by slope,fault,river system and lithology.The high- and medium-prone regions are distributed along the fault zone and the both sides of the Jinsha River and other major river systems.The high-prone areas are concentrated in the surrounding areas such as Yulong County,Songping Township and Dadong Township.Xichuan Village is located in the high-prone areas too.However,there are few landslide points.
