图1 土壤微生物对植物多样性-生态系统功能关系的调控作用概念图。箭头表示路径。植物多样性直接影响生态系统功能(路径1); 植物多样性通过作用于土壤微生物进而影响生态系统功能(路径2); 土壤微生物介导植物多样性-生态系统功能关系(路径3)。AMF: 丛枝菌根真菌; EMF: 外生菌根真菌。

Fig. 1 Conceptual diagram illustrating the role of soil microorganisms in regulating the plant diversity-ecosystem functions relationships. The arrows indicate the pathways. Plant diversity directly influences ecosystem functions (pathway 1), and indirectly influences ecosystem functions through its effects on soil microorganisms (pathway 2). Soil microorganisms directly mediate the plant diversity-ecosystem functions relationships (pathway 3). AMF, Arbuscular mycorrhizal fungi; EMF, Ectomycorrhizal fungi.
