摘要: 采用样方法取样,依据重要值指标运用双向指示种分析(TWINSPAN)法,将山西中条山中段植被群系分成16个群丛。应用丰富度指数(R1R2)、Simpson指数(λ),Shannon-Weiner指数(H′)和均匀度指数(E1E5)研究了16个群丛的植物种多样性。结果表明:群系植物种多样性指数的大小受立地生境和人为活动的综合影响;森林群落的植物种多样性指数明显高于灌丛群落;群落植物种多样性在空间上的差异不仅决定于物种丰富度指数,更与各物种间的均匀度指数密切相关;进而影响不同层次的物种多样性对群落总体物种多样性的贡献。

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(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.

Key words: woody plant community, species diversity, community structure, Midpiece of Zhongtiao Mountains
