摘　　要：应用模糊聚类分析的原理与方法,提出了泥石流危险度评价方法,并以甘肃省48个县以上城市为例,通过模糊聚类分析模型计算,将其划分为极危险、危险、较危险和一般4个危险等级.此方法具有一定的客观性和科学性.By using the principle and method of fuzzy-cluster-analysis, a method of assessment to study the dangerous degrees of debris flows was presented. Taking 48 cities in Gansu province as an example, through the calculation of the fuzzy-cluster model, we have divided the debris flows into four grades, that is, extremely dangerous, dangerous, rather dangerous and general.
