摘要
Based on the discussion the fundamental concepts of δ13C in the global carbon cycle, such as δ13C Suess Effect, observed δ13C ranges of various carbon reservoirs and fractionation between them, this paper introduces the analytical methods in applying δ13C to distinguish carbon source and sink by combining with current observational facts. The various Keeling Plot approaches are introduced to show the achievements in analyzing the background characteristics of atmospheric CO2 and its applicability is also discussed. Finally, the prospects of δ13C research in the global carbon cycle for both observational and theoretical fields are also discussed.
