The species diversity in grazing and cutting on meadow steppe of Stipa baicalensis community was analyzed through field survey.The results showed that species richness in the grazing field was higher than that in cutting field, while species number was lower. The alpha diversity indices under cutting (index of the species richness, species diversity indices, index of species evenness) were higher than that in grazing.
