| Abstract: | The factors affecting the carbon circulation in land ecosystems are expatiated in terms of the influences of the elevation of CO2 concentration on distribution change of carbon quantity overground and underground,turnover of fine roots and litter decomposition.The relationship between the elevated CO2 concentration and soil respiration is also discussed. |
