The impact of climate change on the global hydrological cycle is becoming increasingly significant, with changes in precipitation patterns emerging as a key factor influencing carbon and nitrogen cycling processes alpine wetland ecosystems. However, response nosZ-type denitrifying microbial community its metabolic characteristics source to remains unclear. In this study, high-throughput sequencing nosZ gene LC-MS-based metabolomics were used investigate (4 years) Qinghai Lake. results showed that Microvirga was bacterial group Lake, Azospirillum sensitive ( P < 0.05). 50% rainfall enhancement treatment significantly increased soil moisture, total content an increasing trend increase pH most important explanatory for structure, while diversity. Deterministic dominated assemblage Soil analysis differential metabolites Source Wetland mostly exhibited significant positive correlations. Precipitation affected relative abundance N-Acetylaspartic acid. summary, lower more favorable maintaining storage wetlands variation disrupted existing balance within ecosystem altered structure characteristics. These findings imply change-driven shifts may dynamics wetlands, alter stability, have profound effects communities biogeochemical cycles.
