文摘Regional processes on land-water-air interface carbon(C)budget and balance that interconnect the land and sea are in fact C neutrality critical processes within the earth system.It is therefore essential to quantitatively analyze synergistic landwater-air interface C transport and C exchange processes to gain a deep understanding of the important role that terrestrial ecosystems play in“missing C sink”.This paper systematically analyzes global land-water-air interface C migration processes as well as C budget changes and associated impact mechanisms.It also investigates the important role that these C budgets and C cycling processes play in inland water bodies,respective to C budgets at the land-water-air interface.Moreover,this study reveals the regulatory mechanisms of land-water-air interface C budgets and balances under a background of global climate change.It also quantitatively evaluates the status of China’s regional land-sea-air interface C budgets as well as the C sequestration potential of its lake systems.Finally,this study concludes that the explicit quantification of anthropogenic activity impacts on land-water-air interface C transport and exchange processes is of great significance to global C balances and C neutrality.
