摘要
以云南蒋家沟泥石流为研究对象,通过分析其流域的自然地理环境特征（地貌、地质、气象和水文等）和人类活动的影响,并结合泥石流发生的必要条件（地形坡降、水和松散固体物质）,探讨了蒋家沟泥石流形成的原因,总结了泥石流灾害在蒋家沟流域的分布规律和特征,最后根据泥石流的危害性特点提出了相应的防治措施。
Debris flow is a type of natural hazard that occurs suddenly in mountainous regions and can bring great damage to the economic development and the lives and property of local residents. Jiangjia Valley in the northeast part of Yunnan province is famous for the activity of debris flow. The cause of debris flow hazard in Jiangjia Valley is analyzed in detail on the basis of both the natural environment in the basin and the economic activity of local residents. Then corresponding countermeasures were put ;orward according to the characteristics of debris flowo This research is of certain significance to the prediction and mitigation of debris flow hazard in Jiangjia Valley.
