Voityuk B. Halophytic vegetation of the North-West Black Sea coast (synataxonomy. present condition, transformation directions, protection and using)

Syntaxonomy of North-West Black Sea Coast halophytic vegetation was elaborated by the means of J. Brown-Blanquet method. Scheme developed consists of 11 classes, 17 orders, 22 alliances and 95 vegetation associations. Syntaxons of halophytic vegetation were characterized by the floristic structure, synecology and synmorphology. Diagostic meanings were estimated for syntaxons of different ranks. With the purpose of floristic affinity determination between syntaxons and confirmation of self-dependent existence in rank of association's class of steppe vegetation on saline substrates (class Festuco-Limonietea) phytoindicative and relatively floristic analyses of halophytic vegetation syntaxons were made. Halophytic vegetation syntoxons analysis on their phytosozological value was also conducted. Phytocenotic range of some rarity species of halophytic vegetation existence was described and was used in the making recommendations for the protection of individual syntaxons. Main directions of syntaxons transformation of association's rank were described under the changes various environmental abiotic factors and under the anthropological stress. Major patterns of relationship of halophytic vegetation distribution on North-West Black Sea Coast were characterized.
