Wetland ecosystems are essential to the global carbon cycle, and they contribute significantly storage regulation. While existing studies have explored individual effects of water depth, vegetation, soil properties on organic (SOC) components, a comprehensive study interactions between these factors is still lacking, particularly regarding their collective impact composition SOC in wetland soils. This paper focused Huixian Li River Basin. The variations its fractions, namely dissolved carbon, microbial biomass light fraction mineral-associated under different depths vegetation conditions were examined. Additionally, (pH bulk density, total phosphorus (TP), nitrogen (TN), ammonium (NH4-N), nitrate (NO3-N)) changes components quantified. Specific depth–vegetation combinations favor accumulation, with Cladium chinense at depth 20 cm Phragmites communis 40 exhibiting higher content. positively correlated plant biomass, TP, TN, NH4-N. coupling had significant effect contributing 74.4% variation fractions. Among them, explained 7.8%, 7.3%, 6.4% changes, respectively, 25.6% changes. three influenced components. Optimal level management strategic planting can enhance capacity increase research offers valuable insights for effectively managing sinks reserves.

Amid global climate change, the pursuit of low-carbon development has become a unified international goal. The Qinba Mountain region plays an important role in maintaining China's ecological security, making spatial zoning tailored for carbon neutrality vital local sustainable development. Using land use and socioeconomic data from 2000 to 2020 81 county-level units, neutral framework was developed, considering natural, economic, resource factors. This study further integrated spatiotemporal dynamics index multi-scenario predictions future emission (CE) zoning. results revealed that had overall positive net-carbon trend without significant deficits, central faced increased CE northern weak carrying capacity. predicted continued decrease under scenario reached 30.55 million t by 2060, with only nine units failing reach their peaking 2030. Five different zones were identified: sink functional zone, stabilization high-carbon control zone source optimization zone. Tailored strategies each proposed enhance regional environment contribute green These findings offer insights into achieving regions or cities.
