METHANE EMISSION IN THE FOREST-TUNDRA: TOWARDS THE «STANDARD MODEL» (AA2) FOR WEST SIBERIA
The paper describes a conception of “standard model” for methane emission from the mires of West Siberia. The “standard model” is a complex of (i) methane flux probability densities distributions for typical ecosystems of all natural zones, (ii) period of CH4 emission for all zones, and (iii) fraction of wetland area for all zones. We present experimental data (methane fluxes in forest-tundra) which are the components of “standard model” Aa1. The medians of methane fluxes from palsе, oligotrophic hollows, peat mats and poor fens are 0,14, 1,12, 11,86 and 1,28 mgC•m-2•h-1 accordingly. All abovementioned values relate only to “period of methane emission” which is 120 days in forest tundra.
Keywords: methane emission, West Siberia, forest-tundra, palsе mires
