- Abstract:
-
Effect of vegetation being destroyed and reclaimed on rill erosion on the slope land has been reseached in this paper,using field investigation and simulated rainfall data,It is shown that after vegetation being destroyed and cultivated,rill erosion on the slope land rapidly develops,rill width is 5~30cm,rill depth is 5~15cm,rill erosion amount is 2 200~6700t/km2·a,The value of rill depth and rill erosion amount are smaller than those in the hilly-gullied area of loess plateau,Once occuring rill erosion in the slope land,rill erosion occupies dominant position as rainfall continues developing,Erosion of rill head back-ward is a main erosion way in the process of rill erosion development,Effect of rainfall and topography factors on rill erosion in very obvi-ous.
