摘要
桑日县绒乡江塘村帕堆沟泥石流流域岩石裸露,少有植被固土固源,温差较大,岩石风化严重,降雨多表现出区域性强降雨,易引发泥石流形成。文中分析了泥石流的形成机制,评价了易发程度。
Debris flow disaster often occurs in Rongxiang area of Sangri County,due to undeveloped vegetation,bare rocks,climate impact,greater temperature difference,severely weathered rocks and regional heavy rainfall that is easy to cause debris flow.The formation mechanism of debris flow is discussed and the degree of susceptibility assessed in this paper.
