植被覆盖对泥石流发育的影响分析

Effect of Vegetation Cover on Debris Flow Development

本文就植被对泥石流形成的影响,综合目前的研究成果,进行分析总结,认为植被对泥石流的影响应该辩证地看待。通过植被在泥石流形成前后的作用分析可知,在泥石流形成初期,植被覆盖区对泥石流的形成具有抑制作用,土体中水分达到饱和后对泥石流的形成就有促进作用。

This paper summarizes the research results at present to analyze the impact of the vegetation on the formation of debris flow,and thinks that the impact of vegetation on the debris flow should be treated dialectically.Through the analysis of the effect of the vegetation on the debris flow formation,it showed that at the beginning of the formation of debris flow,the vegetation area can inhibit the formation of debris flow,and after the soil moisture reaches saturation,debris flow is promoted.
