Impact of Grassland Distribution on Runoff and Sediment Yield on Loess Slope
In order to study the effect of grass-belt arrangement on soil and water loss control on slope,the effect of grass-belt distribution on soil and water conservation by artificial simulated rainfall experiment is analyzed in this paper.The results show that the grass belt in the middle and lower part of the slope has a good function of sediment reduction and water storage.The influence of runoff erosion on the downhill slope is the lowest..The grass belt located in the middle and lower part of the upper slope can reduce the acceleration rate of runoff,and the runoff and sediment content of the slope can be significantly reduced,which can better prevent soil erosion.The above research provides reference for preventing soil erosion on slope.
