| 英文摘要 | Plant roots and arbuscular mycorrhizal fungi (AMF) form a ubiquitous symbiosis in terrestrial ecosystems and critically affect soil organic carbon (SOC) dynamics. However, how roots and AMF mediate the impact of reactive nitrogen (Nr) and climate warming on SOC remains unclear. Using a multi-year Nr addition and simulated warming experiment in a semi-arid grassland, we show that Nr input and warming alter SOC by reshaping plant communities and inducing multidimensional tradeoffs among fine-root traits and AMF communities. Stable isotope (13C) tracing revealed that Nr- and warming-induced changes in roots and AMF reduced C input belowground, and mineral-associated organic C and microbial necromass in soil, while stimulating organic C decomposition. Nr input also increased soil N:P ratios and shifted AMF communities toward taxa with finer extraradical hyphae, weakening SOC protection. Together, these findings highlight root-AMF interactions as critical regulators and improve predictions of long-term SOC dynamics under future climate change. |
