Abstract:
The purpose of this study is to develop sensitivity analysis of regional landslide by Logistic regression model. The west area of Wushan County was chosen as a research area. The Logistic regression model was built that in independent vari- ables were landform, physiognomy, lithological character and geological structure and dependent variable was landslide loca- tion data. The research area was divided into 14 450 cells by 10 m× 10 m based on MAPGIS. It is concluded that the sensi- tivity factors of landslide in research area are gradient(between 15° and 30°), height(below 300 m), orientation of slope (south), strata(T2b1and T2b3), slope direction(consequent slope and tangential slope), distance to structural line affecting the slope(less than 60 m)The result can be used in prevention of hazard, land use planning.
