In order to study the effect of vegetation coverage on runoff and sediment yield of natural slope in Pisha sandstone region,illustrate the runoff and sediment reduction effect of vegetation coverage,we conducted runoff scouring experiment,in which the scouring flow rate was 200L/h,on slopes in Pisha sandstone region.The slopes covered by 4different types of vegetation(grass,korshinskpeashrub,Chinese pine and seabuckthorn)and bare slope were selected.The degree of these slopes were about 10°.The runoff and s...
