滑坡危险度区划方法及其应用

    Landslide fatalness zoning method and its application

    • 摘要: 在滑坡研究的基础上总结了滑坡危险度区划的研究方法。建立了综合因素分析和本底因素评价的指标体系,提出了综合因素叠加法、本底因素贡献权重叠加法和本底因素模糊判别推理法的区划模型,介绍了这些方法的应用及试验结果。还对滑坡危险度区划研究中存在的3个主要问题进行了讨论:评价指标数量选择、最佳权重确定方法和危险性等级划分的标准。

       

      Abstract: This paper has summarized methodologies for landslide fatalness zoning. Evaluation system based on comprehensive factor and background factor analysis are set up as well as three zoning modeling methods including comprehensive factors superposition, background factors contribution weight superposition and background factors fuzzy discrimination, relative application and experimental results are also introduced. Moreover, three major problems are also discussed, namely, evaluation index selection, establishment of optimal weight and fatalness classification.
