如何通过野外调查证据对隐蔽性强的低频泥石流进行早期识别对山区的防灾减灾具有实践意义。在对潘沟泥石流的物源特征、形成过程机制、堆积区特征及沟口树木特征调查访问的基础上,通过综合证据分析,认为潘沟泥石流的暴发频率较低,并在此基础上探讨了基于野外调查的低频泥石流的识别方法,预测了泥石流的发展趋势,可为类似孕灾背景的泥石流的防治提供依据。
How to identify early-stage low-frequency debris flow through field investigation is of practical significance to disaster prevention and mitigation in mountainous areas. Based on the investigation of the source characteristics, mechanism of formation process, characteristics of accumulation area and characteristics of Mizoguchi tree in Panzhai debris flow, through the comprehensive evidence analysis, it is considered that the outbreak frequency of Panzhai debris flow is low, and on this basis, Based on field investigation, the identification method of low-frequency debris flow is used to predict the development trend of debris flow, which can provide basis for the prevention and control of debris flow in the background of pregnancy.
