摘　　要：热水沟位于海螺沟风景区,该沟泥石流对流域下游的景区公路和二号营形成极大的威胁。在对热水沟实地调查的基础上,研究了2010年热水沟泥石流动力学特征。根据热水沟泥石流一般规模较小,流速较大,破坏力较大,沟内滑坡堵溃会加大泥石流规模和破坏力的特征,提出了在现有专业监测的基础上增加滑坡监测、以排导为主,稳、拦为辅的工程措施和加强对游客防灾减灾知识宣传的防治对策。Reshui gully is located in Hailuo valley scenic spot, the debris flow poses a great threat to the scenic road and section 2, which are located in the lower reaches of the basin. Based on the field survey, dynamic characteristics of debris flow in 2010 were researched. According to the dynamic parameters of the debris flow, the scale of debris flow is generally small, the flow rate is larger, and the destructive force is larger. The blocking gully and dam break of the landslide will increase the scale and destructive force of the debris flow. The debris flow should increase landslide monitoring and engineering measures. It is necessary to publicize the knowledge of disaster prevention and reduction to tourists.
