 In order to scientifically evaluate the geological hazard susceptibility of Jiangcun street in Xi??an, the authors have conducted detailed investigation for the geological environment and geohazard conditions at Jiang? cun street. An evaluation index system on geological hazard susceptibility has been developed, which involves 9 factors, including slope degree, direction, height, type, stratum lithologies, slope structure, distance away from fault and road, and vegetation coverage, by determining the weight of each factor using hierarchy analysis method. Based on GIS, the weighted information and comprehensive index methods are used to evaluate the vulnerability of geological hazards in the study area, respectively. The results of the two methods are compared in combination with the actual situation and ROC curve. The results show that the results of the two evaluation methods are basically consistent, with the evaluation accuracy of 92.6% and 89.5% , respectively, showing a high accuracy. However, the evaluation results of the information method are of concentrated and continued distribution features, while the concentrating degree of the comprehensive index method is relatively low. It is concluded that the evaluation results of the comprehensive index method is more consistent with the real situation of the study area.
