Title: Plant species diversity of woody plant communities in midpiece of Zhongtiao Mountains
Abstract: 62 samples collected in Midpiece of Zhongtiao Mountains were classified into 16 associations by Two-way Indicator Species Analysis(TWINSPAN).The characteristics of the plant species diversity of 16 associations were studied by using of the formulas of richness indices(R_1?R_5),Simpson's indices(λ),Shannon-Weiner's indices(H′) and evenness indices(E_1?E_5).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.
