Report on Scientific Research Work: 144 pages, 10 charts, 9 pictures, 5 appendices, 85 sources. The object of research - the flora model phytosystems four Ukrainian steppe reserve branches and vegetation technogenic ecotopes south-east of Ukraine. Subject of research - and especially their dynamics florogenesis. Research Methods: expeditionary field and semi-analytic (structural and comparative analysis of floras model objects, typological and taxonomic analysis of the flora isolates). The purpose of work - based on monitoring studies of model objects of different types of anthropogenically transformed floras and populations of indigenous tree species of the southeast of Ukraine to identify and assess the characteristics of their operations and adapt to the modern stage antropogeogeneza. Monitoring of the state of flora and vegetation in different types of transformed floras of the south-east of Ukraine. Floral compiled lists of these areas, established increase in the number of species, particularly invasive, in offices compared to the inventory data of 15-30-year-old. At the same time isolated and characterized group was significantly missing rare species (0.8% of the total number of species of flora Donetsk region). It was revealed that floristic composition model floras within the objects of natural reserve fund comprises from 69 to 1008 species, with the direct dependence of values ??of species richness of the area flora isolate (a significant number of species in a small area is maintained only if the landscape heterogeneity of the reserve). Taxonomically and typological analysis of flora meadow pasture southeast of Ukraine. As a result of a critical study of the flora, today it includes 475 species from 206 genera and 48 families, representing 24% of the species, 34% of births and 37% of births flora of the region. Versatile performance analysis of the family and clan of the spectra, the typological structure of flora meadow pasture indicate inherent features of synanthropic nature. This is evidenced by a significant number of species of dry habitats with short life cycles, a significant proportion of sinantropofitona, as well as the large number of adventitious species. Investigated the variety of protected species and adventive fraction model floras. It was found that the investigated areas adventization ratio ranges from 10% to 17%. The greatest factor are "Khomutovskaya Steppe" and "Belenky." According to the analysis of the spatial distribution of species of adventive fraction model floras highest degree of permanence found 7 species: Descurainia sophia, Centaurea diffusa, Cichorium intybus, Hyoscyamus niger, Cynoglossum officinale, Ballota nigra, Bromus squarrosus. In 4 model floras adventitious presence of 20 species, 3 - 24 species, in 2 - 27 species; only one type 62 flora occur. It is noted that the increase in the number of adventitious species in the last 20 years shows inconsistency floras territories confront threats fitoinvazy. It recommended the introduction of preventive measures to prevent the entry of alien species and measures to control and elimination of adventitious plants.
