According to the characteristics of the three regions of Shaanxi province soil landslide,we select 9 factors to establish the risk assessment standard,use entropy theory to determine objectively the weight of each factor,calculate of multi index synthetic attribute,and combine the attribute recognition theory and the confidence criterion and risk evaluation of 10 typical landslides.Through the field investigation,the evaluation results are basically consistent with the actual situation.%根据陕西省三大区域土质滑坡的特点,选取9个影响因素,建立滑坡危险度评价分级标准,利用熵权理论客观地确定出各影响因素的权重,计算多指标综合属性测度,结合属性识别理论和置信度判别准则,对10个典型滑坡进行危险度评价.通过实地调查,评价结果与实际情况基本一致.
