摘要：

Using metal rods to simulate the effects of contour grass strips in a laboratory experiment, significant differences were observed in their effectiveness in controlling soil loss for different plant densities, slopes and discharges; there was also a significant interaction effect between plant density and slope. With a simulated plant density of about 3000 plants/m(2), contour grass strips reduced sediment concentrations to at least one-third of that recorded with a bare soil control on slopes between 5 and 10%. On slopes of 20% the grass strips increased the erosion twofold.
