摘　　要：澜沧江左岸的一级支流巴迪沟,在最近几十年中一共发生过4次较大规模的泥石流。在现场调查分析以及大量的试验结果的基础上,针对泥石流的特征,通过对泥石流物源区、流通区、堆积区的详细调查,对泥石流的成因进行分析。提出针对泥石流沟的防治对策:以设置雨量计等监测预警为主要手段,辅以必要的工程治理措施(挡土墙、排导槽和防护堤),结合恢复植被等生物手段对泥石流沟进行全面防治,可以有效减少泥石流对水电站的威胁。The Badi gully is one of the first-grade tributaries of Lancangjiang River in Yunnan of China. The distance of the Badi gully from the Lidi hydropower station is 4.9 km. There has been four great debris flows in the gully during the last decades. The debris flow directly threatens the croplands, the Deqing-Weixi high-road and dam. The authors get the formation mechanism of the debris flow by investigating provenance area, circulate area, and accumulation area based on the field investigation and test analysis in room. This paper brings forward all prevention measures that take the monitor and the early warning as the primary measure and the engineering prevention （retaining wall, drainage canal and levee） as the accessorial measure aiming at the characters of the debris flows based on the field investigation. These measures can effectively reduce the threaten to the hydropower station.
