Conceptual model of driving mechanisms associated with dissolved carbon storage and flux and China’s inland water carbon budget (IMAGE)
Caption
Dissolved carbon storage across China's inland waters has increased significantly over the past 30 years, with riverine carbon fluxes primarily driven by climate and human factors, while lake and reservoir carbon storage are dominated by water chemistry controls. Inland waters, as important reactors and regulators of C transport, storage, and emissions, may have a significant impact on the terrestrial C balance. As a critical component of the global carbon cycle, China's inland waters emit approximately 97.9 Tg C/yr into the atmosphere, transport approximately 74.6 Tg C/yr through rivers, and export approximately 64.4 Tg C/yr to coastal areas.
