摘要： Forest rewilding is expected to help support nature restoration and mitigate climate change by promoting soil carbon (C) stocks. Increases in biodiversity after decades of rewilding may affect forest soil C stocks; however, the relative contribution of subordinate and dominant tree species diversity to soil C stocks after decades of forest rewilding remains poorly understood. Here, we conducted a standardized field survey to investigate how subordinate (i.e. rarer) and dominant (i.e. more common) tree species diversity (determined based on basal area) correlate with multiple aspects of soil C stocks (i.e. total soil C stock, dissolved organic C, microbial residue C, and microbial respiration) after 31 years of the establishment of a forest plantation in a subtropical ecosystem. We found that both subordinate and dominant tree species diversity were positively correlated with soil C stock, dissolved organic C, microbial residue C, and microbial respiration. Meanwhile, tree functional traits (e.g. the proportion of N-fixing taxa) among subordinate species were positively correlated with bacterial residue C. Strikingly, subordinate tree species diversity explained a larger portion of variation in soil C stock compared with the diversity of dominant tree species. Structural equation model (SEM) further suggested that subordinate plant biodiversity influenced soil C stocks via its influence on plant traits. Synthesis and applications. Our work provides new insights on the crucial role of subordinate tree species diversity in supporting C stocks after decades-long rewilding of a subtropical forest. Therefore, the preservation of the rarer subordinate plant species is fundamental to develop sustainable forest management strategies, and for policymakers to promote climate change mitigating ecosystem services.
