Abstract:
A typological map of wetlands in the southern taiga of West Siberia has been compiled based on high-resolution Landsat images. In accordance with the new map, the area of southern-taiga wetlands is estimated at 12.02 Mha at the total wetland area percentage in the subzone estimated at 28%. The final accuracy of determination of various wetland classes is 80%. The use of the new map improved the estimates of methane emissions from southern-taiga wetlands from 0.84 to 1.57 MtCH₄/year, i.e., by 87%. The respiration of wetland ecosystems in the southern taiga of the West Siberia is estimated at 67 MtCO₂/year.
