Landscape approach to studying Tomsk region mires

Mire ecosystems influence allcomponents of the geographical system. Mires, as well as other geographical complex, formed due to the interaction of the landscapecomponent (crust, soil, biota, atmosphere) combined by the vertical flow of material and energy in the polydominant geosystem.Specialists of many sciences take interest in mires due to their complex structure. A number of approaches to mire study are formed e.g.hydrological, botanical, pedological, geological and landscape ones. The landscape approach is less developed. It uses methods based onthe idea of landscape geosphere differentiation into several environmental systems having a genetic unity and associated by a lateralprocess set. The goal of the work is justification of the need to use the landscape approach for wetland investigation. The followingproblems were solved: choice and detail research of the key area, wetland large-scale landscape and geobotanical map composing basedon field investigation data and satellite image interpretation. Investigations have been conducted since 2006 to present. 7 key areas werechosen in order to perform a large scale landscape structure research. The key areas belong to the southern taiga subzone and locate 120-150 km northwest from Tomsk. The total area of the key areas is 530 km2. The research shows that landscape investigation has a systemsapproach and allows us to consider the area under study from all the sides taking into account different natural components. Thisapproach has significant advantages. The analysis of geobotanical and landscape maps showed that the former do not reflect the fulldiversity of the object, especially its origins. The paper deals with the comparison of landscape and geobotanical maps as researchresults using a different approach. The analysis of maps marked differences in the classification and spatial structure of the plot. Thelandscape map makes it possible not only to define the vegetation, soil, bedrock, relief border but also to identify the territory genesisand dynamics. The landscape approach to mires study allows recording the spatial combination of environmental systems components inorder to do environmental management and give forecast of the Tomsk region wetland areas further development.
