Abstract: The study of plant responses to grazing is an important part in probing the mechanisms of livestock-plant interaction and of grassland degradation, and to understand the species characteristics and dynamics as well as the species composition of plant community under the disturbance of grazing will provide a scientific basis for the establishment of grazing management policy-making system and the scientific management of natural grassland. In this paper, the research progress in the plant compensation and its mechanism, plant morphological plasticity, and plant community structure under the disturbance of grazing was summarized, and the further researches about the over-compensatory mechanism of different plant communities, the response pattern of plant to grazing, and the long-term effects of grazing to plant individual and community were prospected.
