摘　　要：为提高滑坡地质灾害危险性区域等级划分的准确度,基于影响滑坡因素的代表性指标,地形地貌、岩石构造、人类影响等建立综合评价体系。首先,采用改进层次分析法(analytic hierarchy process, AHP)确各指标权重,简化判断矩阵一致性检验过程,利用AHP-熵权法优化组合赋权,根据权重结果确定重要影响因素,将各影响因素权重与模糊综合评价(fuzzy comprehensive evaluation, FCE)相结合。采用专家评分法计算定性指标量化值,建立滑坡灾害模糊综合评价模型。最后,以元谋县监测数据进行验证。结果表明,该方法能够有效的提升模型精确度,准确预测各区域对应的滑坡危险等级,为相关部门提供一定的借鉴经验。In order to improve the accuracy of regional classification of landslide hazards, a comprehensive evaluation system is established based on the representative indicators of landslide factors, topography, rock structure and human influence. First of all, the improved analytic hierarchy process(AHP) is used to determine the weight of each index and simplify the consistency test process of judgment matrix. The AHP entropy weight method is used to optimize the combination weighting. According to the weight results, the important influencing factors are determined, and the weight of each influencing factor is combined with fuzzy comprehensive evaluation(FCE). The quantitative value of qualitative index is calculated by expert scoring method, and the fuzzy comprehensive evaluation model of landslide disaster is established. Finally, the monitoring data of Yuanmou County are used for verification, and the results show that this method can effectively improve the accuracy of the model, accurately predict the corresponding landslide risk level of each region, and provide some reference for the relevant departments.
