Landslide susceptibility Evaluation of Xide County Based on Logistic Regression Model
[Purposes]Through the systematic analysis of the development characteristics and laws of geo-logical disasters in Xide County,this study provides reference for local geological disaster prevention and control.[Methods]This paper takes Xide County as the research area,selects 11 influencing factors,ana-lyzes the spatial distribution of landslides,and evaluates the susceptibility of landslide disasters in Xide County by establishing a logistic regression model.[Findings]The results show that landslides in Xide County are distributed at an elevation of 2 000～2 600 meters;a slope of 10°～30°;a north-east direction;a middle slope;a distance of less than 100 meters from a road;the distance from the water system is less than 200 m;the distance from the village is less than 500 m;the distance from the fault is less than 3500 m;NDVI was 0.7～0.8;the stratum is Cretaceous;land use is cultivated land.landslide-prone areas are located in the surrounding area of Luji fault,Lengduji fault,Mishihe fault,Zhadu fault zone.[Conclusions]The zoning results of landslide susceptibility can be directly used in the prevention and control of landslide disasters,and also have certain reference value for site selection of engineering construction.
