摘要/Abstract

摘要： 运用Gleason物种丰富度指数、Shannon Wiener指数、Pielou均匀度指数、Simpson指数、生态优势度指数、均优多指数和群落优势度指数对缙云山森林群落林隙与非林隙物种多样性进行了研究,对群落稳定性进行了探讨.结果表明,林隙以个体数为基础的物种丰富度为12.14,Shannon Wiener指数为4.62,均匀度为0.70,Simpson指数为13.32,灌木层所起作用较大;非林隙林分各项物种多样性指数明显低于林隙,依次为6.32、3.74、0.66、8.16.林隙植物群落物种多样性指数显著高于非林隙,而生态优势度和群落优势度又明显低于非林隙,表明作为自然干扰和人为干扰的产物,林隙的存在增加了群落物种多样性,但同时也降低了群落的稳定性.

Abstract: The species diversity and community stability of gap and non-gap stands in Jinyun Mountain were studied by using species richness index(d_GL),Shannon-Weiner index,Pielou evenness index(J),Simpson index(D),ecological dominance(λ), evenness-dominance-abundance index(Z) and community dominance(C).The results showed that the d GL,H',Jand Dcalculated by individuals numbers in gap are 12.14,4.62, 0.70,13.32,respectively.Shrub layer plays a greater role than other layers.The corresponding indices in non-gap stand are 6.32, 3.74, 0.66 and 8.16,respectively,which were lower than those in gap.Species diversity indices of the community were far higher in gap than in non-gap. However,ecological dominance and community dominance in gap were smaller than those in non-gap significantly.It suggested that species diversity of the community increased, and community stability decreased, due to the existence of gap formed by natural or human disturbance.
