BOG ORGANIC SOILS AND BOGS OF RUSSIA AND CARBON POOL OF THEIR PEATS

摘要

The total area of excessively moist peat soils of Russia has been determined on the basis of 1:2.5 million Soil Map of RSFSR, peat deposit survey data and scientific-literature analyses. It equals 369 million ha (21.6 percent of territory) including 139 million ha of soils with peat layer thickness more than 0.3 m. The peats of bog soils and bogs contain 97 to 133 billion tons of carbon. Seventy-three percent of peat lands are in the permafrost zone where the soils with peat layer thickness more than 0.3 m predominate.
