Short summary
We employed stable isotope and ¹³C nuclear magnetic resonance spectroscopy analyses to characterize soil organic carbon sources and stability in Dongting Lake wetlands. Our results revealed vegetation elevated soil organic carbon (Miscanthus: 13.76; Carex: 12.98 g kg-1 > mudflat: 6.88 g kg-1), with plant-derived carbon dominating (47.5–53.3 %). Miscanthus exhibited lower soil organic carbon stability (high O-alkyl C), suggesting a higher risk of organic carbon loss in its floodplain ecosystems.
