摘　　要：对贝加尔针茅草甸草原在不同放牧强度下的植被群落特征进行研究。结果表明:零放牧、适度放牧和重度放牧植被群落的平均高度、密度、盖度和生物量依次呈递减趋势,且存在显著性差异。不同的放牧强度下植物种类变化没有太大差异,重要值波动不大,群落较稳定。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.
