闽北檫树群落乔木层物种多样性特征研究

Research on species diversity characteristics of the arbor layer in Sassafras tzumu community

摘要: 采用对数级数模型对檫树群落物种多度分布格局进行预测与检验结果表明，该檫树群落物种多度分布遵从对数级数分布，即群落的均匀度相对较小，群落稳定且具有较高的生物多样性。

Abstract: The log series model is used to calculate and inspect the arbor species of Sassafras tzumu community，the resuits show that the arbor species obey the logarithmic series distribution and the biodiversity of Sassafras tzumu community is fairly high and stable．
