摘要

Based on the three-year standard runoff plot experiment observation through typical runoff plots from 2006 to 2008, this study quantitatively analyzes the effect and difference of runoff and sediment reduction with different soil and water conservation measures in red-soil slope land of Poyang Lake Basin in order to solve the soil losses problems. Surface vegetation, especially the cover of near surface vegetation has extremely obvious effect on runoff and sediment reduction. When the optimal allocation of different layers of vegetation, good effects can be achieved. The function of runoff and sediment reduction of contour cultivation is more obvious than that of downslope cultivation. The reduction effect of terrace is good and grass planting on the ridge of terrace is much better.
