摘要
文县是近年来确定的全国十七个重点地质灾害防治区之一。本文在分析文县燕儿沟自然地理、地质环境概况的基础上,研究了文县燕儿沟泥石流形成的条件,认为制约泥石流形成主要因素主要有地形因素、松散固体物质补给因素、降水因素等三个方面。
Wenxian County,Gansu is one of the seventeen key geological disaster prevention and control regions in China,identified in recent years.On the basis of physical geography and geological environment analysis,this paper studied the formation conditions of debris flow in Yaner Gully,Wenxian County,Gansu in detail.Results showed that the main factors that restrict the formation of debris flow were mainly terrain factors,loose solid material supply factors,precipitation factors.
