Chinkina T. Syntaxonomy and anthropogenic dynamics of vegetation of the river Dnieper mouth zone

The thesis is devoted to study of systematic variety and anthropogenic vegetation changes of the river Dnieper mouth zone; as well as elaboration of the nature protection and vegetative cover optimizing strategy. A comparative and structural analysis of the flora within the framework of geocomplex has been carried out and its peculiarities have been distinguished. The main regularities of the territorial vegetative cover distribution have been established, the syntaxonomic vegetation composition has been undertaken and the vegetation classification has been developed ( in compliance with the method of Braun-Blanquet). The general diagram of the vegetative cover changes has been devised and their main directions and trends have been distinguished. Anthropogenic and nature-anthropogenic changes that predominate have been ascertained. Among them, dominant ones are hydrogenic. The anthropogenic changes of the vegetation, its peculiarities, main directions and trends have been studied. Contemporary conditions of the vegetation area protection have been analysed. Scientific fundamentals and practical recommendations on conservation of genetic and coenotic variety of vegetation cover have been worked out. Perspective net-work of protected zones has been singled out.
