Summary

In the thesis the results of investigation on the composition and structure of flora and vegetation from 6 small rivers at the left bank Middle Pruth, Delia, Nârnova, Lăpuşna, Sărata, Tigheci, Larga were presented.

On the base of performed investigations the floristic composition of above-mentioned meadow grassland small rivers, which include 406 species of vascular plant, appertaining to 209 genuses and 62 families was established. 31 species of rare plant, compounding 7,6% of land flora were revealed. The analysis of flora from the taxonomic, ecological, bioform, geoelement and economical importance points of views was carried out.

The phytocoenotic composition of the meadow grassland small rivers was established and coenotaxonomical epitome was compound. The vegetable associations were attributed to 4 types of vegetation: aquatic-paludal, pratal, ruderal, forestry. The described phytocoenosis comprises 27 vegetable associations, classified to 17 alliances and 2 sub-alliances, 14 orders and 9 classes. In two associations as edificatory-plants are the rare plant species.

On the base of obtained data the vegetation charts of the meadows grassland of the rivers Delia, Nârnova, Lăpuşna, Sărata, Tigheci and Larga were established. The recommendations concerning the conservation of flora and vegetation and sustainable use of studied meadow grassland were elaborated.
