英文摘要China's wetlands store substantial carbon in vegetation and soils,yet depth-resolved estimates remain inconsistent. Using 18,798 field records (2000-2023), we integrated vegetation and soil data at 20-cm intervals (0-100 cm) to map carbon stocks nationwide. Combining climate, soil, vegetation and topography, a Random Forest model produced spatial estimates of vegetation carbon (aboveground 385.4 Tg C; belowground 662.26 Tg C; total 1047.66 +/- 437 Tg C) and soil carbon (0-100 cm: 8336.51 +/- 1216 Tg C). Climate and topography dominated spatial variability, while performance was higher for the aboveground than for the deeper soil layers. These maps can be used to identify priority regions for conservation and hydrological restoration, providing actionable baselines for wetland carbon management and China's mitigation targets.
