英文摘要Global warming has increasingly detrimental impacts on the structure and function of the Tibetan Plateau ecosystem. However, the mechanism by which warming affects the biogeochemical processes, and consequently the microbial nutrient limitation in soil aggregates, is not clear. In this study, we implemented a 21-year long-term open-top-chamber (OTCs) warming experiment to reveal the warming effects on the soil aggregate microbial nutrient limitation mechanisms in a Tibetan alpine meadow and shrubland. Long-term warming significantly decreased soil aggregate-associated organic carbon (SOC) and total nitrogen (TN) concentrations in alpine meadows, but promoted soil carbon pool in alpine shrublands. SOC and TN concentrations in microaggregate (MIGA: < 0.25 mm) showed the greatest in alpine meadows. Soil enzyme activities increased with the decrease in aggregate size, and enzyme stoichiometry results demonstrated that soil microbes in alpine meadows and shrubland were limited by phosphorus (P); moreover, the long-term warming significantly aggravated the soil aggregate microbial P limitation in the shrubland. Meanwhile, the long-term warming had no significant effect on microbial C limitation in the alpine meadow and shrubland, but soil aggregate size mediated the microbial C limitation patterns and showed the greatest C limitation in MIGA. Phosphorus limitation is likely to be an important constraint to the development of alpine ecosystems in future climate warming, and the protection of MIGA is one of the important mechanisms for carbon pool sequestration.
