摘要
本文简述了北京北山地区泥石流灾害的基本情况，并运用灰色关联分析的方法，对本区泥石流活动的危险性进行了定量化分析。在此基础上建立了区域泥石流危险性评价的数学模型，并据此对本区的１１个小流域进行了危险性评价。
It introduces the basic situation of the mud-rock flow disaster in the northern mountains of Beijing.Using the method of grey-connected analysis,the author has worked out a fixed quantity analysis of the mud-rock flow disaster in the study area.A mathematic model of the regional dangerous character assessment of the mud-rock flow disaster has been established,and has assessed the dangerous character of about 11 small drainage area in the study area.
