Abstract
The analysis of biomorphological structure of flora is possible to set the features of ecological terms of the particular region. On the basis of floristic researches in the period of 2001 –2014 inthe lower reaches of the Dniester – Tiligul the spectrum of vital forms for the flora of the valleys of the estuaries was determined. Domination of hemicryptophytes (52.6 %) and therophytes (28.9 %) was determined. In local flora of the valleys of the estuaries grades of dominant groups do not change; there are insignificant variation of species amount of the said vital forms in comparison with a similar to index for the general flora of estuaries. By the amount of hemicryptophytes, and phanerophytes, the flora of the valleys of the inspected estuaries approaches the indexes for the Middle European flora. The presence of artificial arboreal-shrub planting of different plantation has a considerable influence on the amount of species of phanerophytes and hamephytes. A great amount of therophytes can be related with synantropical species of plants which are distinctive for the region from transformation of its territory. It is possible to assume the presence of leveling of regional signs of the flora of the valleys of the estuaries and appearance of new lines due to the change of natural landscapes. On the basis of our investigation it is possible to indicate the leveling of valleys and estuaries flora and appearance of new signs due to the change of natural landscapes.
