Kulizhskiy S.P., Loyko S.V., Gerber A.A. DISTRIBUTION PATTERNS OF SOILS IN THE FOREST TUNDRA OF WEST SIBERIA (RIGHT BANK IN THE MIDDLE OF THE RIVER PUR)Hydrocarbon resources are extracted on significant areas in the forest-tundra zone of Western Siberia. The main hydrocarbon production and transportation facilities in the area of the Pur-Taz interfluve are located in the direction of Urengoy-Novozapolyarny-Tazovsky. The active development of the interfluve by oil and gas companies requires additional research. However, at present research in this area is not enough. Therefore, the purpose of this work is to determine the soil composition of the Pur-Taz interfluve within the right coastal terraces and adjacent interfluve spaces in the middle reaches of the river Pur. Soils of cryomethamorphic separation are most common in the interfluve. Depending on the stages of post-pyrogenic vegetation larch forests with illuvial-ferruginous and cryometamorphic soils are formed under larch forests with a lead vegetation cover of dwarf birch. Large-coarse humus cryometamorphic soils are formed in depressions under dwarf birch and Labrador tea vegetation. Soils lithologically heterogeneous are often found. Podzols are formed on the second terrace. Podzols illuvial-ferruginous and illuvial-humus-ferruginous are on a slope near dwarf birch, ice and lichen vegetation. Alluvial peaty-coarse-humus soils are formed in the cone of removal of beams under birch firs. Peat soils of frozen marshes predominate on the first terrace of the river Pur. Peat-gleyzems occupy the lower parts of the gutters and peat oligotrophic-elevated positions. Thus, the study of the composition of the soil cover on the right bank of the river Pur defined the complex geomorphological and geological structure of the territory. It determines the wide variety and contrast of moistening conditions of soils, which affects the soil-forming processes and forms the structure of the soil cover.Key words: soil cover; components of the soil cover; Pur-Taz interfluve; cryometamorphic soils.
