Аннотация: In order to assess the methane fluxes from the russian soils to the atmosphere the following steps have been taken: 1)Information concerning soil types, areas, and coordinates for the soils of Russian was collected from the FAO/UNESCO (1974) Soil map of the world. 2) A database, based on experiments described in the literature, was generated concerning methane fluxes and environmental parameters influencing the fluxes. 3) Representative methane fluxes for the majority of the temperate, boreal and tundra soils were calculated based on the database. 4) The period of biological activity (PBA) for the different soils was estimated based on their geographical location. 5) Based on the above information the total annual methane fluxes are estimated based on the different soil's capacities to produce or consume methane. There are very few regions and ecosystems investigated by field measurements in comparison with the natural diversity. Thus, many soil units are not characterized by any measurements of the methane fluxes. The majority of the soil units with measurements represent automorphic soils and wetlands and wet soils are not sufficiently represented.
