Kolomiichuk V. Structure, Dynamics and Protection of Coastal Ecosystems Phyitodiversity of the Sea of Azov

The thesis presents the results of a comprehensive analysis of phytodiversity of the Sea of Azov coastal zone. The history of botanical research of the Sea of Azov coastal zone is analyzed. It is established that the flora of vascular plants of the Sea of Azov includes 1924 species from 613 genera, 122 families and 4 departments. Various types of analysis have been performed, on the basis of which the flora characteristics are elucidated. Synanthropic fraction of the Sea of Azov coastal zone flora is investigated, its analysis is made, the level and characteristics of its synanthropization is studied. Syntaxonomical composition of regional vegetation by dominant classification is established (7 types of vegetation, 149 formation and 517 associations). Syntaxonomical scheme of the vegetation is developed on the basis of floristic classification of Braun-Blanquet school, which includes 22 classes, 30 orders, 46 unions, 160 associations. Among these, 1 union and 5 associations are described for the first time. Natural and anthropogenic changes of the vegetation of the region are analyzed. The current status of taxa populations, which are protected at international, national and regional levels and plant communities of the “Green Book” is clarified. On the basis of sozological analysis it is offered to add 6 species of the Sea of Azov coastal zone flora to the 4th edition of the Red Data Book of Ukraine, and 4 rare formations – to the 3rd edition of the Green Data Book of Ukraine. Measures and recommendations for protection and sustainable use of phytodiversity within the Sea of Azov coastal zone are proposed. The Red Data Book of Pryazov’ya region, ecological network and system of Important Plant Areas, which have been developed by us, will make it possible to improve nature conservation in Pryazov’ya.
