宁夏贺兰山区贺兰沟泥石流发育特征研究

Research on Development Characteristics of the Helangou Debris Flow in Helan Mountain of Ningxia

通过对宁夏贺兰山区贺兰沟泥石流的现场勘查,分析了泥石流形成的地形地貌条件、物源条件、水源条件,在此基础上对泥石流的发育特征进行了研究,并对泥石流基本特征参数进行了计算,从而对其危险性进行了定量的评价。为贺兰山岩画保护区泥石流的防治提供了一定的参考。

Basing on the field exploration on the Helangou Debris flow in Helan Mountain of Ningxia,the geomorphological conditions and source conditions and water sources of debris flow have been analyzed.On the basis above,the developmen characteristics of debris flow have been studied,and the basement of parameters of debris flow have been calculated,and the risk degree has been assessed further.It provides some reference for the prevention and control of debris flow in the Rock-art Zone of Helan Mountains.
