Short summary
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.

Short summary
We conducted a Carex brevicuspis leaf litter input experiment to clarify the intrinsic factors controlling litter decomposition and quantify its contribution to the soil organic carbon pool at different water levels. Our results revealed that the water level in natural wetlands influenced litter decomposition mainly by leaching and microbial activity, by extension, and affected the wetland surface carbon pool.
