摘　　要：本文以北京市房山区为例,针对风景区泥石流进行特征分析。阐述了泥石流的分布现状和主要特点,分析了区内泥石流对其沟域内景观资源、旅游设施以及人员安全的危害。从泥石流沟所在区域的地形地貌、地层岩性、物源及降雨条件等4个方面,进行了泥石流成因研究分析。研究区泥石流易发程度综合评判结果显示区内有5条属于易发性泥石流,7条为轻度易发泥石流。This study analyzes the characteristics of debris flow scenic spot in Fangshan District of Beijing.Firstly,it explains the distribution and main characteristics of debris flow;secondly,it introduces the hazard of landscape resources;thirdly,it introduces the harm of debris flow disaster to the landscape resources,tourist facilities and personnel safety in the gully area.Subsequently,the causes of debris flow are analyzed from four aspects,such as landform,topography,lithology,source and rainfall conditions in the area of debris flow.Comprehensive evaluation of debris flow susceptibility show that 5 debris flows are vulnerable in the area,the other 7 flows are light vulnerable.
