Abstract
We present the results from studying the spatio-temporal organization of southern and subtaiga and forest-steppe geosystems of regions of the South of Western Siberia, including the Irtysh, Tobol, Ishim and Tobol-Tavda interfluve area, and the southern Ural, reflecting spatio-temporal variability of landscape structure in these regions, conducted its mapping, the estimation of the dynamic state variables of geosystems with the purpose of solving practical, forward-looking, environmental protection and expert tasks. The landscape structure of the study area was mapped based on the principles of structurally dynamic landscape science and the genetic classification of forest types using modern GIS technologies, including automated interpretation of Earth remote sensing data (ERS). This approach allows us to use forest taxational data in landscape studies. The geographic information landscape mapping scheme, implemented on the basis of Hansen mosaic data, made it possible to construct digital raster landscape maps of the study area, reflecting the spatio-temporal organization of geosystems and the zonal distribution of forests in the region. Automated processing of ERSdata enabled determination of the landscape structure as well as calculating the areas of different anthropogenically disturbed territories (felling areas and burning) and correlation of various types of geosystems.
