| 摘 要： | 本文针对北京景区泥石流破坏的特点,确定其资源价值,生态环境、生命财产的损失为评价主体。采用层次分析法确定了各评价体系中评价因子的权重,建立了以加权求和法为计算基础的评价模型,并利用该模型对2002年发生于云蒙山景区的泥石流进行了灾情评估。

| Abstract: | A model has been established to appraise the hazards caused by the debris-flow,which includes damage for resources,ecology,environment,life and property in Beijing scenery spots.This evaluation model is based on the combination of analytic hierarchy process and weighting summation of different appraisal factors.The validity of the model provoked in this study is confirmed through evaluating the loss caused by a debris-flow occurred in Yunmengshan scenery spot in 2002. |
