Section: Methodology and research methods. Models and forecasts
The spatial differentiation of landscape varieties of drained lake basins is characterized, based on spectral analysis of land cover surface using satellite images. The studies were conducted at the key site located in the southeast of the Bolshezemelskaya Tundra, where dozens of lake basins were artificially drained in the late 1970s. Assessment of landscape differentiation patterns both at the level of individual natural territorial complexes and their groups can be carried out using a set of geoinformation, statistical and classification analysis methods. At present, willow and dwarf-shrub tundra predominate in the drained lake basins, whereas meadows and swampy hollows are less represented. The landscape differences of the basins are grouped according to the dominant vegetation and degree of drainage. Classification using abbreviation-numerical formulas is proposed to characterize landscape differentiation of the basins. The studied basins are classified mainly as moderately bushy medium-drained. Statistical relationships between the values of spectral indices and the structure of landscape differences are calculated. Correlative relations between quantitative values of spectral indices, identified levels of bushiness and drainage degree of the basins are defined. Application of the complex of methods shows that the basins drained more than forty years ago have stabilized in the aspect of landscape differentiation. Testing of the complex of methods for naturally drained basins reveals the possibility of the method application for other areas of the Bolshezemelskaya tundra.
