Analysis Of Vegetation Factor In The Debris Flow Of Hillslope Occurrence

How does vegetation protect and reinforce soil mass in the slope, accordingly inhibit the occurrence and development of debris flow of hillslope.It's a new area of interdisciplinary nature to this problem. On the basis of deficiency of vegetation analysis factor study on debris flow of hillslope,this article has a lot of research on debris flow of hill slope in Beibei ,Chongqing. On this basis, vegetation and soil mass with different vegetation coverage are studied together. From this study, we can see that vegetation can modulate overland runoff, improve soil mass structure and enhance the anti-erosion of soil mass well. So vegetation inhibits the occurrence of debris flow of hill slope effectively, and it plays a role in protecting overland soil mass.The full article is divided into the following six parts:The first part is the overview of the studied region. It sums up the geographical position and natural conditions of Beibei in Chongqing. And according to the actual studying situation, it illustrates the background, concept and methodology of this research work.The second part introduces the overall of debris flow of hill slope in Beibei.It generals the characteristics of time and spatial distribution and hazards of debris flow of hill slope.The third part introduces some results we studied before briefly. It contains some important factors analysis which can affect debris flow of hillslope, for example, geology, geomorphology, hydrology and meteorology, human activities.The fourth part is the major study contents. It illustrates the roles that vegetation plays in the occurrence of debris flow of hill slope according to field visits and indoor and outdoor studys.This part is divided into two parts. The first part analyses vegetation stopping rainfall, modulating overland runoff and protecting overland soil. From this part we can see that good vegetation coverage and enough ground covers can reduce rainfall's...
