The global CO2 flux from soils is an important regulator of climate change as well as determinant of net ecosystem C balance (Baggs, 2006). The territory of Russia occupies more than 1/9 of the land surface. The role of Russian soils in the global carbon cycle is very considerable; Therefore, more accurate estimates of the carbon fluxes from the terrestrial ecosystems of Russia should be obtained.

lusions ions:

Ш The presented estimation of total CO2 flux from Russian terrestrial ecosystems (5.67 Gt/yr) could be approximately addressed to the 1990s – the initial period of Kyoto Protocol. Ш Uncertainties of this estimation depend upon amount and quality of available experimental data, accuracy and resolution of the soil map at scale 1:5 million, spatial aggregation techniques and regression models used. Ш To update this estimate, it needs to increase the numbers and the geographical representatives of long- term measurements, and to use up-to-date areas of croplands, grasslands and forests on Russian territory.
