The characteristics of community and main plant species were studied under rotational grazing and continuousgrazing in desert steppe ofStipa breviflore.The results showed that the height,coverage,and density of the population and the main plant species under rotational grazing were higher than that under continuous grazing during the period of the experiment in three years.The range conditionimproved apparently under rotational grazing,however,the height,coverage,and density of degenerative plants,annual pl...
