地下群落通常比相应的地上群落支持更大的生物多样性，虽然调节其多样性的因素远未得到很好的理解，但最近越来越多的研究提供了与理解这些因素如何运作有关的数据。本文综述了生物因素如何影响土壤生物主要类群的群落多样性，并探讨了其影响机制。在最局部的尺度上，土壤生物多样性可能会受到营养水平内的相互作用或直接营养相互作用的影响。在土壤中，体型较大的无脊椎动物也可以通过促进扩散和改变土壤生境来影响较小生物的多样性。在更大的尺度上，单个植物物种效应、植被组成、植物物种多样性、植物凋落物类型的混合以及地上营养相互作用都对土壤生物多样性产生影响。此外，在景观尺度上，土壤多样性也对植被的变化和演替做出响应。本审查还考虑了如何从概念上理解土壤生物多样性的生物驱动因素可能有助于我们了解社区和生态系统生态学中的关键主题，如地上-地下相互作用，以及生物多样性和生态系统功能之间的关系。它的结论是，更好地了解是什么驱动器在土壤中的生命的多样性，纳入适当的概念框架，应显着帮助我们了解陆地社区的结构和功能。
Belowground communities usually support a much greater diversity of organisms than do corresponding aboveground ones, and while the factors that regulate their diversity are far less well understood, a growing number of recent studies have presented data relevant to understanding how these factors operate. This review considers how biotic factors influence community diversity within major groups of soil organisms across a broad spectrum of spatial scales, and addresses the mechanisms involved. At the most local scale, soil biodiversity may potentially be affected by interactions within trophic levels or by direct trophic interactions. Within the soil, larger bodied invertebrates can also influence diversity of smaller sized organisms by promoting dispersal and through modification of the soil habitat. At larger scales, individual plant species effects, vegetation composition, plant species diversity, mixing of plant litter types, and aboveground trophic interactions, all impact on soil biodiversity. Further, at the landscape scale, soil diversity also responds to vegetation change and succession. This review also considers how a conceptual understanding of the biotic drivers of soil biodiversity may assist our knowledge of key topics in community and ecosystem ecology, such as aboveground-belowground interactions, and the relationship between biodiversity and ecosystem functioning. It is concluded that an improved understanding of what drives the diversity of life in the soil, incorporated within appropriate conceptual frameworks, should significantly aid our understanding of the structure and functioning of terrestrial communities.
