Effects of slope and defoliation intensity on the effectiveness of desert wheatgrass for reduced runoff and soil erosion under simulated rainfall
Introduction In order to protect reservoir from non-point source pollution,one of the best management practices is to restore the sloping farmlands to grasslands in the areas surrounding the reservoir.Desert wheatgrass ( A gropyron desertotrum ( Fisch.) Schult.) is notable for its drought resistance and strong ability to stabilize soils and reduce erosion due to the deep penetration of root system and easy establishment.The objective of this study was to evaluate the effects of slope and defoliation intensity on the effectiveness of desert wheatgrass for runoff and sediment reduction.
