根据典型滑坡的强度指标和可能性指标选取相对高差、坡度、坡体结构、坡型、地层岩性、地层关系、滑坡体积和块石含量等8个评价因子，利用信息熵法、层次分析法与综合权重法分别计算出各评价因子的权重，并对白龙江流域21个典型滑坡进行危险度区划，将3种权重值计算的危险度分级结果进行比较。结果表明：专家权重和信息熵权重危险度分级结果一致率为76%，信息熵权重和综合权重危险度分级结果一致率为86%，专家权重和综合权重危险度分级结果一致率为90%，因此，综合权重得到的危险度分级较其他两种方法更为准确可靠。%From a typical landslide’s intensity indexes and potential indexes were selected the following eight factors: the relative elevation, slope, slope structure, slope type, stratum lithology, stratigraphic relationships, landslide volume and stone contents; then the eight factors were evaluated and the information entropy weight and expert weight of the eight factors were worked out by using AHP and the entropy principle. At the same time, the information entropy weight and expert weight were accorded the same status so as to facilitate their participation in the comprehensive weight calculation. Then a hazard degree assessment was made of 21 typical landslides that had occurred in the Bailong River Basin by calculating the three aspects including the expert weight, entropy weight and comprehensive weight. A comparision of the results showed that the concordance rate of the risk classification of expert weight and information entropy weight reached 76%, the that of the risk classification of information entropy weight and the comprehensive weight reached 86%, and that of the risk classification of expert weight and the comprehensive weight reached 90%. Therefore, the risk classification result of the comprehensive weight was more accurate and reliable than the others.
