摘要
Abstract
Taking the Tujia and Miao Autonomous Prefecture of Xiangxi,Hunan Province for example,based on regional spatial data,we select-ed 12 evaluation factors such as elevation,slope and slope direction to carry out analysis at first.Then,coupled the frequency ratio method,infor-mation volume method and evidence weighting method with logistic regression model respectively,and made the landslide susceptibility assess-ment map for comparison.Finally,we analyzed and discussed the evaluation results of optimal coupling model.The results show that①geologi-cal lithology and slope are the key factors affecting the occurrence of landslide in the study area.②The coupling model of frequency ratio and logistic regression has higher prediction precision,and its results are more suitable for providing reference for the prediction and early warning of landslide disaster in the Tujia and Miao Autonomous Prefecture of Xiangxi.③Landslide in the study area is greatly affected by human activities.The high susceptibility areas are obvious at the intersection of roads and urban edges,while the low susceptibility areas are mainly concentrated in high-altitude mountainous areas.关键词
