摘　　要：在分析历史资料和防治现状的基础上引入城市重要性作为判别准则之一,以18个地级市为研究对象利用层次分析法对河南省泥石流危险度分区。依据泥石流危险度权重的不同将河南省分为5个区间,其中危险度大的城市1个,危险度中等的城市3个,危险度小的城市6个,危险度极小城市2个,无危险度城市6个。以期为河南省泥石流灾害的防治提供有益的参考。Based on historical and realistic data, debris flow hazard of 18 cities in Henan province were researched using AHP. As a new criterion, city-importance was introduced in evaluation system of AHP. Henan province was divided into five intervals based on hazard degree weights of debris flow. Among 18 cities, one city belongs to large-hazard-area, 3 cities belong to medium-hazard-area, 6 cities belong to small-hazard-area, 2 cities belong to minimum-hazard-area, and 6 cities belong to no-hazard-area. Moreover, a formula was got to forecast the occurrence of debris flow in Henan.
