摘 要: 物种多度分布是生物多样性研究的重要内容.应用对数模型对万木林中亚热带常绿阔叶林林隙的物种多度进行预测与检验.结果表明:万木林中亚热带常绿阔叶林林隙内外的乔木和灌木物种多度都遵从对数级数分布. Species abundance distribution is an important task of biodiversity research. The log series model was used to calculate and inspect the species in the gaps in central subtropical evergreen broadqeaved forests. The results show that both the arbor tree species and the shrub tree species in and out of the gaps obeyed a logarithmic series distribution.
