| Abstract: | The effect of human reclamation on modern erosion was puantitively analyzed by study on relationship between human reclamation and evalution process of sloping surface. It was estimated that in loess hilly and gully region, the slope erosion might be increased about 25% by reclamation and cultivation. |
