Abstract: The formation of the seismic landslide is complex, and factors influencing the seismic landslide are multitudinous. Meantime, the influence of different factor is different. In the previous study, the choice of importance of the factors is often subjective. Analytic Hierarchy Process is used to decide the importance of each factor, which overcomes the subjective ingredient, applies fuzzy method into studying the regional hazard of seismic landslide, combines with GIS and then depicts the seismic landslide hazard map.

Key words: seismic landslide, analytic hierarchy process (AHP), fuzzy math method

摘要: 地震滑坡的形成机制复杂,影响因素众多,但各个因素对滑坡稳定性的影响却不一样。以往的研究中,对影响因素权重的确定主观因素有很大的影响。在前人研究的基础上,利用层次分析法对地震滑坡各影响因素的权重进行确定,较好地克服了主观因素的影响,在此基础上利用模糊数学的方法对研究区域的地震滑坡危险性进行评定,编制了地震滑坡危险性评价图。
