Abstract:

Estimating carbon storage of terrestrial ecosystem and understanding its spatial distribution and temporal evolution are the key to the carbon cycle study. This article summarizes some major results of the estimations of terrestrial ecosystem carbon storage in globe and China, including the existing problems and uncertainties in the studies. Progress in studies of the carbon storage change since the Last Glacial Maximum ( including the Mid- Holocene) and the influencing factors, especially the potential relationships between the changes and the anomalous increase of the atmospheric carbon dioxide since 8.2 ka B.P. is evaluated. A main conclusion that could be drawn from the overview is that the increase in atmospheric carbon gases (CO2、 CH4) concentrations seems coincident with the decline of the terrestrial carbon storage during the mid to late Holocene, and these might have been caused by the impact of anthropogenic activities on terrestrial vegetation during the agricultural era in the old continents.

Key words: carbon storage, China, Holocene, LGM, terrestrial ecosystem
