Abstract: Historically, water and wind erosions were assumed to be the major forms of soil erosion. Though the studies of tillage-induced erosion have been developed greatly in recent years, few studies were made on grazing-induced erosion. This paper discussed the significance of the research on grazing-induced erosion, and reviewed the current status and existed problems of the research, based on both domestic and foreign researches. Grazing-induced erosion induces the redistribution of soil matters on overgrazing grassland as a direct result of animals. As a vector of overgrazing, grazing-induced erosion is a study area which deserves greater attention in the future. The research on grazing-induced erosion not only benefits the determination of livestock carrying capacity and the increase of soil carbon sequestration, but also has an indicative meaning on diagnosing the degradation degree of grassland and on managing degraded grassland.
