最近对β多样性的研究增加，产生了一系列令人困惑的概念、测量和方法。在这里，我们通过一系列的使命陈述提供了一个最广泛使用的和生态相关的分析方法的路线图。我们区分了两种类型的β多样性：沿梯度的定向转换与非定向变化。不同的测量方法强调生态数据的不同属性。这些属性包括对存在/缺席与相对丰度信息的强调程度，以及包括与排除联合缺席。明智地同时使用多种度量可以揭示给定数据集的beta多样性模式的潜在本质。对印度尼西亚珊瑚组合的个案研究显示了多方面方法的效用。我们主张仔细考虑相关问题，并辅以适当的分析。零模型的严格应用也将有助于揭示驱动β多样性中观察到的模式的潜在过程。
P>A recent increase in studies of beta diversity has yielded a confusing array of concepts, measures and methods. Here, we provide a roadmap of the most widely used and ecologically relevant approaches for analysis through a series of mission statements. We distinguish two types of beta diversity: directional turnover along a gradient vs. non-directional variation. Different measures emphasize different properties of ecological data. Such properties include the degree of emphasis on presence/absence vs. relative abundance information and the inclusion vs. exclusion of joint absences. Judicious use of multiple measures in concert can uncover the underlying nature of patterns in beta diversity for a given dataset. A case study of Indonesian coral assemblages shows the utility of a multi-faceted approach. We advocate careful consideration of relevant questions, matched by appropriate analyses. The rigorous application of null models will also help to reveal potential processes driving observed patterns in beta diversity.
