Abstract:: A study on soil and water conservation capacity of three introduced grasses under artificial simulated rainfall was conducted in contrast to the farmland and the bareland. The results showed that three grasses have good soil and water conservation capacity. The Setaria sphacelata cv. Narok is the best. The water movement times are successively bareland > farmland > Trifolium repens cv. Haifa > Pennisetum clandestinum cv. Whittet > Setaria sphacelata cv. Narok. The runoff and sediment accumulant as well as soil erosion under 76 mm/h artificial simulated rainfall are successively farmland > bareland > Trifolium repens cv. Haifa > Pennisetum clandestinum cv. Whittet > Setaria sphacelata cv. Narok. The runoff and sediment accumulant as well as soil erosion under 53 mm/h artificial simulated rainfall are successively bareland > farmland > Trifolium repens cv. Haifa > Pennisetum clandestinum cv. Whittet > Setaria sphacelata cv. Narok.
