Abstract：Aiming at the frequent occurrence oflandslide disasters in the western mountainous areas of Xingtai City， the information model is used to analyze the landslide susceptibility bycoupling the analytic hierarchy process， entropy weight method，combination weighting method and random forest model.Twelve evaluation indexes were selected to calculate the subjective weight，objective weight，comprehensive weight and information value，and the randomforest model was trained.The reliabilityof the evaluation resultsof the four models was analyzed.The results show that rainfall，stratum lithology and slope have great influence on landslide disasters in the study area. The information-coupled random forest model has the highest accuracyand good applicability.The research conclusions provide a reference for landslide susceptibility assessment in complex geological environment.
