摘要
An attempt has been made to estimate the carbon dioxide budget of Sweden. Fluxes considered include fossil-fuel combustion and limestone processing as well as changes in the carbon stores in forests, peatlands, cultivated soils and sediments. The estimations indicate that more than half of the carbon released as carbon dioxide during fossil-fuel combustion (c. 16 Mton C per year) is currently accumulating in terrestrial ecosystems, mainly in the form of forest biomass (c. 9 Mton C per year). Cultivated organic soils release c. 1-2 Mton C per year to the atmosphere, while peat and the sediments of lakes and coastal waters accumulate c. 4 Mton C per year.
