This paper introduces a rule-of-thumb coordinate system based on sediment delivery ratio (SDR) and soil humin content (SHC) in order to evaluate the net effect of soil erosion, sediment transport and deposition on CO2 flux in river basins. The SDR
the middle sub-basin as the main source region, and the lower as the main sink. For comparison, sediment-movement-related CO2 fluxes of 8 other major basins in 4 continents are examined.
