| 摘 要： | 运用α和β物种多样性指数分析热带地区海南中部山区草地、灌丛、次生林和原始林植被演替过程中物种多样性变化规律。结果表明,物种丰富度指数、Margalef's指数和Shannon-Wiener指数能较好地反映不同演替阶段间的物种多样性大小差异;而Alatalo均匀度指数能较好反映物种分布变化。从草地到原始林阶段,群落α物种多样性呈连续增大趋势。Jac-card和Srenson相异性指数能较好地反映不同演替阶段群落间的物种更替,且呈单峰曲线变化,在灌丛与次生林过渡阶段最大。

| Abstract: | Species Diversity Change Law was analysed with α and β species diversity indexes during the vegetation evolution period of grassland,shrub,secondary forest and primary forest in Hainan mid mountain area,tropical regions.Results showed that species richness index,Margalef's index and Shannon-Wiener index well reflected changes in the magnitude of species diversity,and Alatalo evenness index well reflected changes in species distribution.α species diversity tended to increase with vegetation succession.Dissimilarity indexes of Jaccard and Srenson well showed the change in species turnover,and showed a unimodal curve during succession,reflecting that the index was the highest at the transition stage between shrub stage and secondary forest stage. |
