Peregrym M. Rare and vanishing species of flora Donets’k chain of hills

The thesis deals with studying the current state population of rare and vanishing species of flora Donets’k chain of hills. The results were obtained on basis of study of horology and ecological-coenotic characteristics, age structure and spatial pattern cenopopulations of rare species of flora Donets’k chain of hills. The flora Donets’k chain of hills includes 244 rare and vanishing species of plants. The geographic, ecological-coenotic analyses and sozological estimate of rare and vanishing species were carried out. The spatial pattern and age structure of population rare species of plants were studied. 9 species have of continuum type of spatial pattern of populations, 235 species have of secured type of spatial pattern of populations rare species of plants. Among last, 5 species have of disjunctive type of spatial pattern of populations, 43 species have of line type of spatial pattern of populations, 187 species have of local type of spatial pattern of populations rare species of plants. The protection of phytodiversity of Donets’k chain of hills on different level of organization of environment was analyzed. Recommendations concerning development of regional econet of Donets’k chain of hills and model of regional econet of Donets’k chain of hills were worked out.
