| 英文摘要 | Alien plant invasions profoundly influence soil carbon (C) cycling, yet their mechanisms on the priming effect of soil organic carbon (SOC) decomposition are poorly understood. We selected three coastal wetland community types (non-invaded, moderately invaded and highly invaded community by Spartina alterniflora) across five climatically distinct sites in China to clarify the priming effect of soil organic matter decomposition using 13C-glucose tracer method. In the laboratory experiment, the priming effect was positive in all three community types, with the absolute priming values ranging from 15.6 to 108 mg C kg-1 soil. Heavy S. alterniflora invasion enhanced the priming effect by 43.5%- 76.3% compared to non-invaded soils, with this invasion-induced enhancement being more pronounced in tropical and subtropical zones than in temperate zone. S. alterniflora invasion decreased SOC content, nitrogen (N) availability, and microbial biomass and activity, while increasing the microbial C: N ratio. Structural equation modeling (SEM) provided quantitative support for the finding that the reduction in model-derived microbial carbon use efficiency (CUE) emerges as a key mediating factor of the amplified priming effect in S. alterniflora invaded communities. Our findings highlight that plant invasions can accelerate soil C loss via microbial physiological shifts, underscoring the need to incorporate priming mechanisms into C budget assessments of invaded ecosystems. |
