| 英文摘要 | Rice fields feed almost half of the world's population with the help of soil nitrogen (N) cycling and the resulting N supply. The ongoing global climate change is expected to alter soil N cycling, potentially creating positive feedback to warming through enhanced emissions of nitrous oxide (N2O), a potent greenhouse gas. Yet, the effects of climate change factors on process-specific soil N dynamics and N2O emissions in paddy fields remain unclear. Here, the 15N dilution method was used to quantify gross N transformation rates of waterlogged paddy soils exposed to warming and free air carbon dioxide (CO2) enrichment (T-FACE) for 9 years. The effects of single CO2 enrichment and warming on soil N dynamics were obscured by their combined effects in this study. Gross rates of N mineralization, NH4+ immobilization, and nitrification significantly increased under warming (by 63 %, 58 %, and 16 %, respectively) and under elevated CO2 (by 60 %, 64 %, and 15 %, respectively). Meanwhile, the N2O emission rates increased by 10-and 35-fold under warming and elevated CO2, respectively. In contrast, none of these N-related variables were altered when combined, indicating an antagonistic interaction. Under either elevated CO2 or warming, soil organic matter quantity and quality primarily regulated gross N transformations and N2O emissions with the underlying driver of fungi. Together, these findings suggest that single-factor manipulative experiments may have overestimated the impacts of global change factors on soil N dynamics, highlighting the need to investigate the interactions among multiple global change factors. |
