摘　　要：结合遥感解译及工程地质勘测,对承德围场县西山的两条泥石流沟流域的地形地貌、地层岩性、气象水文等条件进行了分析,并对泥石流沟进行了分区.结合实际情况,采用单沟泥石流危险性评价中的函数赋值模型对勘察区庙台沟和庆沟危险度进行评价,并利用灰色系统关联度理论进行相似性验证,结果显示两条泥石流沟的危险性都是中低度.The urban area located downstream of western mountain area of Weichang county Chengde city has been threatened by several debris flow gullies. Combined with remote sensing interpretation and engineering geological survey, the topography, lithology, hydrometeorology, etc of two debris flow gullies are analyzed, and the debris flow gullies are zoned. Connected with the practical situation, the hazard degree of Miaotai and Qing gullies is calculated by using function assignment model of single debris flow hazard assessment models,and the method of relational grade of grey system is used to have similarity verification. Results show that the hazard degree of the two debris flow gullies is low to moderate.
