摘    要:将二级模糊综合评判的数学模型用于滑坡、泥石流区域危险度的评判。选取了对滑坡、泥石流影响较大的岩石风化系数、地震烈度等18个参评因素。按其属性分为地质、地貌、气候、植被、人类活动等5个类别。先在同类因素之间进行初级评判,再利用初级评判的结果进行类之间的二级评判。以云南昭通地区的11个县(市)为例介绍了滑坡、泥石流区域危险度二级模糊综合评判的方法与步骤。

关 键 词:滑坡  泥石流  危险度  二级模糊综合评判

Abstract:The two level model of the fuzzy comprehensive evaluation is used to estimate landslide and debris flow risk degree of a district.18 physical factors (such as the coefficient of the weathered rock,eathquake intensity and etc.) which influence landslide and debris flow are chosen and divided into 5 types,i.e. geology's,geomorphology's,climate's,vegetation's and human action's.First of all,preliminary evaluations are proceeded in the same type.Then the senior evaluation is proceeded with the results of preliminary evaluations between the all types.As an example,the mothed and steps of the evaluation for Zaotong county in Yunnan Province are introduced.
Keywords:Landslide  Debris flow  Risk degree  Two  level fuzzy comprehensive evaluation
