摘　　要： 繁峙县是山西省泥石流较发育的县市之一,五台山北麓泥石流发育特征比较典型,该泥石流沟位于五台山景区内,严重威胁当地人民生命及财产安全。本文对伯强沟进行了详细的野外调查,获取了研究区泥石流沟的基础数据资料,分析了伯强沟泥石流基本特性,通过对流域物源来源、补给长度、堵塞程度的计算,得出了该泥石流沟的发展阶段及易发程度,结合野外资料采用多因子评价公式,对伯强沟泥石流沟做出了险情等级及危险性评估,得出该泥石流沟处于形成期(青年期)—发展期(壮年期),危险性发生几率大,成灾可能性大的结论,并且针对该泥石流沟的发育特征的认识及数据分析,提出泥石流综合治理的防治对策。 Fanshi County is one of counties where the debris flow is relatively developed in Shanxi Province .The development characteristics of debris fow in northern Mount Wutai is typical. This debris fow ditch located in Mount Wutai, and it is a serious threat to the lives and property of the local people. We got the basic data of the debris flow by the detailed field investigation, then analyzed the characters of the debris flow. Through the calculation of the basin provenance supply source, length, degree of blockage factor, we understood the development stage and the easy degree of the debris fow. Combined with feld data by multi-factor risk assessment of debris flow danger, it shows that the debris flow is at the youth stage to mature stage, with the high risk probability of disaster. Based on the understanding of the development characteristics of debris fow gully and the data analysis, this paper puts forward the countermeasures for the comprehensive control of debris fow.
