东乡族自治县布塄沟泥石流形成条件及发育特征研究

Study on formation conditions and Development Characteristics of Bulleng gully debris flow in Dongxiang Autonomous County

随着极端气候的不断出现,甘肃省临夏回族自治州境内出现了大范围强降雨天气,形成危害性较大的群发性泥石流地质灾害。本文案例中的东乡族自治县布塄沟是一条典型的泥石流沟,通过实地调研,总结了布塄沟泥石流的形成条件、发育特征,以期为临夏州泥石流类地质灾害防治工作提供参考。

With the frequent emergence of extreme weather,Linxia Hui Autonomous Prefecture in Gansu Province is susceptible to dangerous debris flow geological disasters caused by large⁃scale heavy rainfall.In this paper,as a typical debris flow ditch,Dongxiang Autonomous County was chosen as the study object.The formation conditions and development Characteristics of the debris flow were summarized through field investigation,which provided reference for the prevention and control of geological hazards similar with debris flow in Linxia.
