摘　　要：Lakes emit large amounts of carbon dioxide(CO_(2))into the atmosphere with 0.81 Pg C a^(-1)[1],which offsets approximately24%of global land carbon sink.However,there is considerable uncertainty in the estimate due to limited data and the effects of human activity and climate change.In China,lakes exhibit substantial variability in CO_(2)exchange,resulting in uncertainties in national and regional land carbon sink assessments.
