土壤微生物群落是许多重要生态系统功能的关键参与者，容易受到环境干扰，这可能导致微生物多样性和功能的丧失。然而，很少有生态学的概念和实践已经发展为拯救胁迫土壤微生物群落。本研究通过接种丛枝菌根真菌（AMF）和不接种丛枝菌根真菌（AMF），以及在3个植物多样性水平（1种、3种和6种）下进行的实验，研究了丛枝菌根真菌和植被如何从模拟退化的土壤生态系统中拯救土壤氮(N)循环微生物环。结果表明，接种AMF促进了土壤氮循环微生物群落的恢复。这种改善的恢复与AMF在增强N -循环微生物环内相互作用中的作用有关。此外，植物多样性的增加增强了AMF在拯救氮循环微生物群落中的作用。我们的发现为AMF和植物多样性在促进退化的陆地生态系统中微生物群落的拯救中的作用提供了新的见解。
Soil microbial communities, key players of many crucial ecosystem functions, are susceptible to environmental disturbances, which might cause the loss of microbial diversity and functions. However, few ecological concepts and practices have been developed for rescuing stressed soil microbial communities. Here, we manipulated an experiment with or without arbuscular mycorrhizal fungi (AMF) inoculation and at three levels (one, three and six species) of plant diversity to disentangle how the AMF and vegetation rescue soil nitrogen (N) ‐cycling microbial loop from simulated degraded soil ecosystem. Our results showed that AMF inoculation improved the restoration of soil N‐cycling microbial communities. This improved restoration was related to the role of AMF in enhancing interactions within the N‐cycling microbial loop. Furthermore, increased plant diversity strengthened the role of AMF in rescuing N‐cycling microbial communities. Our findings provide novel insights into the roles of AMF and plant diversity in facilitating the rescue of microbial communities in degraded terrestrial ecosystems.
