The studies on erosion process of naturally restored grassland were not only very important for understanding of the effect of naturally restored measures on runoff and sediment reduction, but also necessary for analyzing the reasons of water and sediment dropped in Yellow River. This paper adopted simulating runoff scouring experiment in field runoff plot, studied the erosion process and relationship between runoff and sediment under different conditions. The results showed that: (1)Compared with the bare slope which shelved for 2 months, the runoff and sediment reduction benefits in naturally restored grassland was up to 88.0% and 99.9% separately, and the runoff and sediment reduction benefits in 1-year planted grassland were 47% and 97.6% separately; (2)For naturally restored grassland, there were an obvious effect on the runoff-sediment relationship. Compared to the bare slope and 1-year planted grassland, there were less runoff and sediment in naturally restored grassland, and the runoff-sediment relationship was significantly different; (3) For naturally restored grassland, that the infiltration rate significantly increased was an important reason why the runoff and sediment reduced.
