Theme X. Peatland carbon budgets and greenhouse gas (GHG) fluxes
The regional assessment of carbon balance for peatland ecosystems at the South Taiga of Western Siberia is discussed. The key area located between Iksa and Bakchar rivers (56o58`N 82o36`E) at the Bakcharskoe bog in the Tomsk region, Russia. The basic types of oligotrophic and eutrophic ecosystems were studied. Carbon balance calculated from the emission of СO2 and CH4 from peat soils, net primary production (NPP), and carbon leaching with runoff. The analysis of results has shown that the carbon balance is positive in summer months. The analysis of space images and ground data were used for vegetation classification. Vegetation mapping allows estimating carbon balance for the whole key area and construct maps of NPP, СО2 emission and carbon balance.
