Spatial structure of vegetation cover and top layer of peat of northeastern spurs of the great Vasyugan mire
The use of satellite images for a comprehensive study of natural objects, including the assessment of the current resource potential of wetlands and speed of peat accumulation is relevant in the study of remote areas of wetlands in Western Siberia. Structure of bog complexes is well reflected in the...

The use of satellite images for a comprehensive study of natural objects, including the assessment of the current resource potential of wetlands and speed of peat accumulation is relevant in the study of remote areas of wetlands in Western Siberia. Structure of bog complexes is well reflected in the satellite images due to their indicator properties - texture and color of contours of bog microlandscapes. Satellite images allow evaluating the current state of wetland ecosystems and their violations in connection with the anthropogenic impact. The main aim of the study is to map the surface cover using satellite images for South-Taiga key «Bakchar-Iksa»; to carry out geospatial analysis of the structure of vegetation and the top layer of peat on the basis of the map data and ground surveys. The methods used in the study. Thematic mapping of surface cover of forest-bog complexes at a key area based on satellite images Landsat will identify the areas occupied by different types of bog complexes. A complex of geo-information programs will be used for interpretation of satellite imagery, mapping and assessment calculations. Results. Thematic processing of satellite images Landsat in the ERDAS Imagine system and compilation of digital layers in ArcGIS show clearly the spatial structure of vegetation over «Bakchar-Iksa» key area and allow investigating the compliance between modern vegetation and supplies types of nearurface peat layer at Iksinskoye bog.
