| 摘 要： | 调查三明小湖赤枝栲自然保护区的 41个 10m× 10m样方 ,共 410 0m2 的群落面积 ,测定群落物种多样性特征 ,得到Margalef丰富度指数D1=14.5 6 14;Shannon Wiener多样性指数D2 =5 .4336 ;Simpson多样性指数D3 =0 .95 6 6 ;种间相遇几率PIE =0 .95 6 7;均匀度J =0 .7788.探讨乔木层、灌木层、及藤本的物种多样性特征值 ,其变化趋势与群落总多样性一致 .分析群落中 12个主要乔木种群的年龄结构 ,揭示群落乔木层主要建群种呈稳定型 ,表明该群落正处于相对稳定的群落演替阶段

| Abstract: | The structure and species diversity of 41 plots, 4 100 m 2 area of the Castanopsis kawakamii community in Xiaohu, Sanming City, Fujian were analysed. The results showed that the Margalef richness index (D 1) of this community was 14.561 4, the Shannon-Wiener index (D 2) was 5.433 6, the Simpson index (D 3) was 0.956 6, the PIE was 0.956 7, the Pielou evenness (J) was 0.778 8. The diversity of canopy layer and shrub layer had the same change trend as the whole community. The age structure of 12 dominant tree populations showed that the constructive species are steady populations and the community is an ecosystem of high stability. |
