Abstract: Based on both species-abundance relationship and species diversity, nature of community structure was analyzed under different grazing intensities in alpine meadows and alpine bushlands. The results show that the relative abundance, which accords with the lognormal distribution, demonstrated regular change with growing intensities. Though the community structure changed, the values of indices (e. g. Simpson′s diversity index, λ, shannon′s diversity index H′, McIntosh′s diversity index Dmc evenness index E and species richness R) that are normally used to descibe the nature of communities of different grazing intensities. All above indicate that the changes in community structure can not be explained perfectly by comparing values of species diversity indices only, This result also confirmed the West′s supposition.
