Abstract: The landslide is one of the major geological hazard in our country which is affected by many factors,such as rainfall,topography,elevation,slope gradient,vegetation coverage and human activities etc. Rainfall is the major inducing factor in our country. It is a focus and difficult issue in the academia that how to quantitatively determine the rainfall effect on landslide. Based on the monitoring data of rainfall and landslide in Wanxiu District of Wuzhou, using mathematical statistics method, the statistical relationship between spatial distribution of landslide and rainfall process is established and analyzed by logistic regression model. The critical value of rainfall induced landslide and the probability of landslide could be determine by this method.
