Six plots with different slope

soil and vegetable measures are made to study characteristics of rill develop on stimulant slope and effects of protecting slope using vegetable measures under heavy rain and flow scouring. The results shown rill develop obviously and present complex shape in loess and gravel slope planted with shrub. However

a small quantity of rill is produced in sandstone slope planted with lawn of much cover during the final term of rainfall. The function of protecting slope using vegetable measures is closely related with soil structure and soil bulk density. So

vegetation measures are needed to be put forward according to different slope.
