Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The river valleys are characterized by high diversity of ecosystems, their originality, complex structure and
dynamics. Changes in vertical displacements from the plain to channel in various parts of сatena, which
can be seen as an intricate complex integrating coenoses formation, geomorphological and pedogenic
processes, are very important. Plant communities serve as indicators of territorial and temporal changes.
Combinations of the communities within the ecological series influenced by environmental factors
are characterized as ‘ecomers’, which reflect the trends of ecosystem changes, i.e. ȕ-coenodiversity.
Quantitative assessment of these plant communities is possible based on the synphytoindication
methodology. There were selected three model river valleys, namely, those of the Sluch, Dniester, and
Krasna rivers. Comparison of these rivers is of a special interest because they have different dimensions
and flow in different natural areas. The topological differentiation in ecological series of the river valleys
served for comparison of the ‘ecomers’, i.e. for assessment of ȕ-coenodiversity differentiation towards
changes of leading ecological factors. |
