COMPARATIVE ANALYSIS OF THE GEOGRAPHICAL STRUCTURES OF THE BRYOFLORISTIC COMPLEXES OF BELARUS

   The article considers the issues of the regional geographical analysis of bryofloristic complexes of the Belarus. The studies were made in Belarus and Eastern Europe on the basis of mapping on 390 squares (100 × 100 km). Four subregions (boreal­-Baltic, boreal-­taiga, nemoral-­western and nemoral-­central) are distinguished in the Belarus, the distribution of species of bryophytes was characterized, results of the geographic analysis for each subregion were presented. Studies have shown that the geographical structures of the bryofloristic complexes of Belarus show, on the one hand, their close relationship with the respective bryofloras of the subregions, and on the other hand, a pronounced specificity among themselves, especially those related to different natural regions. Closer ties with the main parts of the subregions show the territories of the nemoral zone, in a smaller one ­ the boreal zone. In general, it can be concluded that on the territory of Belarus bryophytes do not form a single bryoflora, but are represented by 4 interacting fragments of larger bryofloras of the regions (boreal and nemoral) and subregions (boreal-Baltic, boreal­-taiga, nemoral­-western and nemoral-­central).
