Abstract

Background. Territory’s landscape structure directly stipulates territorial differentiation of its anthropogenic transformation. In this connection, studying of landscape structure of the most and the least disturbed territories allows to define the landscapes most subjected to anthropogenic development with the purpose of taking standard areas of such landscapes under special protection and prevention of degradation of types of ecosystems typical for them. The aim of the work is to establish interconnections between the territory’s landscape structure and the level of its anthropogenic transformation and to single out the landscapes typical for territories with strong and weak disturbance.
Materials and methods. As the research materials the author used a landscape map of Belarus, the State land cadaster; the methods included calculation of coefficients characterizing the ecological state of natural environment, administrative district classification by the level of disturbance, and detection of landscape structure of the distinguished classes by facilities of GIS-technologies.
Results. With an increasing of degree of ecological disturbance at administrative districts, a part of elevated and medium-height landscapes, hilly-moraine-erosive, secondary-moraine, loess landscapes and landscapes of river valleys in their structure is also increasing. A part of hilly-moraine-lacustrine, kame-moraine-lacustrine, alluvial-terrace, lacustrine-alluvial, flood-landsand lacustrine-bog landscapes is diminished. According to the lithology of bedrocks, landscapes with the cover of loesslike and water-glacial loams are typical for the strongly disturbed territories, for the weakly disturbed – landscapes with alluvial and water-glacial sands. As for mesorelief features, landscapes with a greater degree of unevenness of ground (hilly, plateau-like) are are typical for more disturbed territories and landscapes with a lesser degree (flat, flat-wavy) – to less disordered.
Conclusions. The research has allowed to distinguish landscapes relating to different classification units that, due their favourability for anthropogenic development and disturbance, must become an object of protection within the framework of the protected areas for preserving types of ecosystems typical for them, and, consequently, the country’s biological diversity on the whole.
