Effect of Grazing Intensity on Characteristics of Grassland Vegetation Communities

The effect of the Community characteristics of Stipa baicalensis meadow grassland under different grazing intensities were studied.The result shown that:The average height,density,coverage and biomass of the community in fence zero-grazing, moderate grazing,heavy grazing followed a decreasing trend,and there are significant differences.Plant species under different grazing intensity is not much difference and important value fluctuations was more stable communities.
