摘要: 植物多样性的提高可以促进生态系统功能, 两者之间的正向关系通常由植物-植物间相互作用来解释, 然而越来越多的研究表明土壤微生物在调控植物多样性-生态系统功能关系方面发挥着重要作用。本文首先综述了植物多样性如何影响土壤微生物, 以及土壤微生物如何影响生态系统功能, 然后重点围绕特定土壤微生物功能群介绍其如何介导植物多样性-生产力关系的相关研究进展。土壤微生物可能通过响应植物多样性的变化, 从而间接地影响生态系统功能; 也可能直接介导了植物多样性与生态系统功能之间的联系。未来研究需重点关注土壤微生物调控植物多样性-生态系统功能关系的途径, 以及量化土壤微生物对植物多样性-生态系统功能关系影响的相对贡献, 为理解全球气候变化背景下生物多样性丧失的影响提供理论依据。

Abstract

Background: Higher plant diversity is known to promote ecosystem functions, with the positive relationship typically attributed to plant-plant interactions. However, a growing body of literature has revealed the crucial role of soil microorganisms in regulating the relationships between plant diversity and ecosystem functions. 

Progresses: This review first summarizes how plant diversity affects soil microbes and how soil microbes, in turn, influence ecosystem functions. It then focuses on the specific soil microbial functional groups and summarizes the research progress on how they mediate the relationships between plant diversity and productivity. Taken together, soil microorganisms may indirectly affect ecosystem functions by responding to changes in plant diversity, or they may also directly mediate the interactions between plant diversity and ecosystem functions. 

Perspectives: Future studies should prioritize the pathways through which soil microbes regulate the relationships between plant diversity and ecosystem functions, as well as quantify the relative contribution of soil microbes and environmental factors to these relationships. This will provide new insights into understanding the impacts of biodiversity loss in the context of global climate change.
