英文摘要The response of the relationship between plants and microbes to nitrogen (N) deposition has attracted considerable attention in the research community; however, results on how N deposition affects the relationship between plants and bacteria, fungi, or both, are inconsistent. In the present study, we estimated how the relationship between plants and the soil microbial community was affected by N deposition in a 5-year N addition experiment at an alpine steppe site in North Tibet. Nitrogen addition not only improved shoot biomass, the litter of shoot biomass, and root biomass, but also changed the composition of the plant community from one dominated by perennial forbs to perennial bunch-grasses. We found significant changes in the soil fungal community, but not in the soil bacterial community. Structural equation modeling revealed that N addition directly influenced the plant community, but not the soil microbial community. The changes in plant composition and biomass revealed that the plant community directly strengthened the abundance of soil fungi and altered its community composition, which is contrary to other research results. Therefore, our findings indicate up-regulating effects of high N availability on plant-fungi interactions in alpine steppe, which may strengthen the relationship between the plant and fungal communities and alter the ecosystem's functions and services.
