The characteristics of the plant species diversity of 16 associations were studied by using of the formulas of richness indices(R1R5), Simpson’s indices(λ), Shannon-Weiner’s indices(H′) and evenness indices(E1E5). The results indicated that:The species diversity indices of 16 associations varied according to the site conditions and anthropogenic effects; The order of the species diversity indices of the 16 associations showed the species diversity of the arbor-shrub-herbaceous was significantly higher than that of the herbaceous;differences in community species diversities, which are not only determined by species richness indices, but also have a closer relationship with the evenness indices of respective species, thus can influence their respective contributions to the overall species diversity. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2006.02.012
