contour cropping
2.The outcomes show that cultivation measures have the reduction functions of run-off energy and slope sediment production, of which, the action of contour cropping is the maximum and the action is reduced along with the increase of rainfall intensity and surface gradient; cultivation measures also have a certain correlation on the reduction functions of run-off energy and erosion, in the meanwhile of slope sediment production, it is effected by the factors of soil erosion resistance and scouring resistance.
