Popis:	102 In this research, a susceptibility prediction model of landslides for the route No. 21 is established using logistic regression. The regression model is obtained using the data of topography, geology and rainfall of four typhoons, Herb, Sinlaku, Mindulle, and Toraji. The classification error matrix and the ROC curve show the accuracy of 81.4% and AUC of 0.771. Both two verification modes show good feasibility of this model. Furthermore, it is further verified by the data of typhoon Morakot with the accuracy of 80.8%. Finally, the susceptibility of each slope unit is predicted with respect to three daily rainfalls of recurrence intervals of 10, 50, and 100 years. The landslide model and susceptibility map along the route No. 21 in the Chenyoulan creek watershed is established.
