英文摘要	Plant richness strongly affects ecosystem functions, especially ecosystem carbon and nutrients stocks. However, the mechanisms underlying positive richness-stock relationships remain uncertain. Plant-fungus linkages play crucial roles in modulating stocks of terrestrial ecosystems, but empirical evidence regarding the integration of soil fungal guilds into positive richness-stock relationship under natural conditions is still lacking. Here, ob-servations from 81 plots along a natural plant richness gradient in oasis-desert ecosystems were used to assess the role of diversity within particular soil fungal guilds in integrating the associations of plant richness with vegetation and topsoil (0-30 cm) carbon (C), nitrogen (N) and phosphorus (P) stocks. We observed that plant richness has positive associations with vegetation and topsoil C, N and P stocks in oases and deserts. Mycorrhizal fungal abundance showed consistent and positive associations with plant richness and vegetation and topsoil C, N and P stocks in the oasis after accounting for groundwater, soil factors and soil enzyme activities, whereas similar patterns were found for saprotrophic fungal abundance in the desert. We further demonstrated mycor-rhizal and saprotrophic fungal abundance as important integrators of the positive richness-stock relationships in oases and deserts, respectively. Moreover, guild-level fungal abundance surpasses whole fungal community at-tributes in linking plant richness and stocks in oases and deserts. The present study provides real-world evidence supporting the crucial roles of fungal functional groups diversity in integrating the positive associations of plant diversity with ecosystem C and nutrients stocks in oasis-desert ecosystems. By unravelling the importance of fungi for ecosystem C and nutrients stocks, our work emphasises that ecosystem restoration should consider not only plant richness to enhance ecosystem C and nutrients stocks but also the roles of key fungal groups.
