Krajobrazy eoliczne obszarów wododziałowych na obszarze Polesia Białoruskiego

Abstract

At watershed area of the neighbourhood of Bobrovichi Lake in the western part of Byelorussian Polessye we deal with morphological effects of both older and contemporary wind activity. The last one has an anthropogenic origin and it reveals in the development of sandy aeolian cover, and also in a form of intensive soil blowing, which however does not give the clear accumulative morphological equivalent (soil blowing is an effect of landscape transformation owing to processes of peatbogs drainage). One should also emphasize that once (about 11 thousand years ago) the human factor laid here at the base of development of older, presently already fixed wind relief. The vegetation adapted here, what is obvious, to rather dry aeolian habitats. In majority of cases it has a forest character — pine coniferous forests Peucedano‑Pinetum and Cladino‑Pinetum with mosses and different species of lichens. In the area investigated Cladonietum mitis is the most widely distributed syntaxon among psammophylous grasses. This association shows different phases of development, from initial to optimal ones. The largest floristic and phytosociologial variety was stated in the most widespread area of drift sands in the range Tupichitsy. Then, the valuable associations are as follows Koelerio‑Astragаletum arenarii and Kochietum arenariae.
