Fig. 3: Comparison of CO2 emissions from Chinese inland waters in the 1980s and 2010s.
From: Substantial decrease in CO2 emissions from Chinese inland waters due to global change
Upper: relative importance of different Strahler order streams in riverine CO2 evasion. Lower: relative contributions of rivers, lakes, and reservoirs in total CO2 efflux. The sizes of the pie charts are proportional to the riverine CO2 evasion flux. Percentage contributions are given for headwater (first–second orders), intermediate (third–fifth orders), and large (sixth–eighth orders) streams.
