摘　　要： 本文针对房山区典型泥石流沟主要物源类型进行分析讨论,崩滑堆积物源、坡面物源以及沟床堆积物源是本区泥石流物源的主要类型。崩滑堆积物源及坡面物源参与泥石流活动的量占其总量相对较少,沟床堆积物源相对较大,并且多为泥石流沟的主要物源。区内佛子庄乡北窖沟泥石流沟床堆积物分析显示,沟道冲淤特征表现出以冲为主的特点,沟床物质是参与泥石流活动的重要物源。并依据北窖沟泥石流物源特点,提出针对性的泥石流防治建议。 The main source types of typical debris fow gully in Fangshan are analyzed and discussed in this paper. The main types of debris fow source in this area are the source of landslide debris, the source of slope and the source of bed sediment. Landslide and slope source provenance in debris fow activities accounted for the total amount is relatively lower. The most of them are the main source of debris fow gully which the source of the bed sediments is relatively higher. The channel siltation characteristic is mainly erosion on analysis of Fozizhuang Town Beijao debris fow bed sediment. The bed material is an important source of debris fow activity participation. It proposed debris fow prevention recommendations on the basis of Beijao debris fow source characteristics.
