An original database on soil descriptions performed in Russia was analyzed.
For different tundra landscapes, the average carbon resources were estimat
ed, and characteristics of their geographical distributions were studied. A
bsolute carbon values in the tundra zone and its regions were calculated. T
he results obtained were compared with relevant published data on Russian a
nd world tundra zones. The total amounts of carbon in the phytomass, phytod
etritus, and soil of Russian tundra areas were compared.
