【Abstract】 This paper presents the benefit of soil preservation on the slope surface over 95; and safety coefficient above 2. 0. The radical cause of soil eroson taking place on the slope surface is investigated and the basic formula about the quantity of energy containing in the small scattered flow is deduced. The effective measures of soil preservation on the slope surface and in the channels are proposed and the safety coeffioient of the benefit index of soil preservation is also proved.更多还原
