GEOINFORMATION ANALYSIS OF SOIL COVER PROTECTION IN THE ARCTIC ZONE OF THE RUSSIAN FEDERATION

The representativeness of the soil diversity in the network of nature protected areas of the Russian Arctic was calculated on the basis of the Soil Map of the Russian Federation, 1:2.5 M scale by using geoinformation analysis. The authors estimated soil cover composition and soil contours areas using the ArcView GIS system. They have identified 90 different soils and soil complexes in the Arctic zone of Russia, 30 of them belong to the Arctic and tundra soils and occupy 47% of total Russian Arctic zone area. In the nature reserves and national parks territory, 48 different soils and soil complexes have been identified, 15 of them belong to the group of arctic and tundra soils, which occupy 60% of the area of protected areas. The investigation shows that currently the existing system of the Arctic protected areas is characterized by high representation of the taxonomic soil diversity (the representativeness indicator is 94%). The only soil type, Arctic Gleezem (Turbic Criosols), is not territorial protected within its typical distribution areas. To optimize the system of Arctic protected areas, the authors propose to adjust the boundaries of the existing nature protected areas in the Anadyr River basin, as well as to consider the possibility of organizing a protected area in the southern part of the Novaya Zemlya Archipelago.
