论文摘要
伦斯特和柯布尔德多样性指数具有许多优点;特别是,它概括了许多现有指数并定义了一个有效的数字。我们提出了一个计划,以量化与该指数的丰富性,均匀性和分类学相似性的贡献。与Van Dam(2019)的工作相比,我们的方法对非均匀社区的均匀性和相似性均无偏见。我们还引入了分类树平衡的概念,该概念应在社区结构的描述中使用。
The Leinster and Cobbold diversity index possesses a number of merits; in particular, it generalises many existing indices and defines an effective number. We present a scheme to quantify the contribution of richness, evenness, and taxonomic similarity to this index. Compared to the work of van Dam (2019), our approach gives unbiased estimates of both evenness and similarity in a non-homogeneous community. We also introduce a notion of taxonomic tree equilibration which should be of use in the description of community structure.
