探讨了基于滑坡灾害定量预测模型的“滑坡类型”分析在滑坡灾害制图中的适用性。本研究所使用的定量预测模式，是建立过去发生的山崩与各种地理资讯间的关系，称为“因果因子”。滑坡专家的一个强烈要求是通过预测模型分析“不同类型的滑坡”。基于先前的研究，决定在许多集成工具中使用模糊集理论模型（使用代数和运算符）进行分析。分析方法分为以下两个阶段：！预测模型产生的预测图的比较，关于各种滑坡类型，如陡坎崩塌、旋转滑坡、平移滑坡、流动和流动滑坡。!地貌学家制作的预测图与灾害图的比较。在这些分析中，提供了两种差异图（称为DIF图-A和DIF图-B）。DIF图-A是由两个预测图针对不同的滑坡类型，而DIF图-B是由每个预测图和由地貌学家产生的危险图。通过对意大利Alpago地区的试验表明，DIF图-A可以分析不同类型滑坡的危险区域，而DIF图-B考虑了专家意见，对于确定不同类型滑坡的危险区域是有效的。
This paper discusses the applicability of analysis on the "landslide types" based on the quantitative prediction model for landslide hazard mapping. The quantitative prediction model used in this study construct the relationship between the past landslide occurrences and various kinds of geographical information termed "causal factors". One of the strong demands of the experts working on the landslide is to analyze the "different types of landslides", through the prediction models. Based on a previous study, it was decided to use a fuzzy-set theory model (using algebraic sum operator) for analysis among many integration tools. The analytical procedure was divided into the following two stages: ! Comparison of the prediction maps produced by the prediction model, with respect to the various landslide types, such as scarp collapse, rotational landslide, translational landslide, flow and flowslide. ! Comparison between the prediction maps and the hazard map made by the geomorphologist. In these analyses, two kinds of difference maps (termed DIF map-A and DIF map-B) were provided. The DIF map-A is made by the two prediction maps with respect to the different landslide types, while the DIF map-B is made by each prediction map and the hazard map produced by the geomorphologist. Based on the experiment for the Alpago region in Italy, it is indicated that the hazardous area affected by the different landslide types could be analyzed through the DIF map-A, furthermore, the DIF map-B taking account of the expert's opinion is effective to find out the hazardous area with respect to the landslide types.
