摘　　要：叙述了云南省永胜县期纳镇三道河泥石流的发育特征、危害对象,并对该地区泥石流成因进行了分析。阐述了泥石流的形成条件,并对物源区物源条件等局部滑坡崩塌情况进行分析。描述并分析了泥石流诱发因素及形成机制。提出三道河泥石流以"拦固排护结合,以拦排为主"的治理方案,以保护三道河流域居民的生命财产安全。This paper describes the developmental characteristics and harmful objects of debris flow in Qina Town, Yongsheng County, Yunnan Province, and analyzes the causes of debris flow in this area. The forming conditions of debris flow are expounded, and the conditions of local landslide collapse, such as the material source condition in the source area, are analyzed. The characteristics and formation mechanism of debris flow are described and analyzed. In order to protect the life and property of residents in Sandaohe River Basin, the paper puts forward the control scheme of debris flow in Sandaohe River by combining the blocking and drainage with retaining and drainage.
