Nesplyak O. Ecological peculiarities of asheslag dumps' flora and vegetation of Burshtynska thermal electric power station and their using in recultivation.

Object - phithocomponent of technogenic ecosystems of different types of Burshtynska thermal electric power station. The aim is to study the peculiarities of ecotope vegetable component of of Burshtynska thermal electric power station. The methods are geobotanical, floral, taxation, chemical-analytical, cartographic, pedology, mathematics and statistics. For the first time the flora and vegetation on active and closed asheslag dumps were studied. The systematic, ecological, biomorphologic and florocenotypical structure were studied too. There were found out 217 species of plants that belong to 165 genera which join into 51 families. In the ecological range mesophytes and masotrophics are dominated. The biomorphological analysis showed that the taproot polycarpics were the most numerous. The synanthropic component was leading. The physico-chemical characteristic of esheslag dumps edaphotopes was given. The contents of chemical elements in various organs of medicinal plants and biological accumulation coefficient of microelements in them were revealed. The morphometric parameters of plants depending on the type of asheslag dumps were investigated. The ecological peculiarities of three initial stages of syngenetics succession of plant groups were marked. The classification of asheslag dumps vegetation was proposed. Basing on asheslag dumps' flora and vegetation studying, their ecological characteristics, the list of recommended trees, shrubs and herbaceous plants and phytorecultivation technology to improve the environmental conditions of the territory were presented.
