Golubnycha S. The influence of conditions of water-cooling reservoirs of South Easten Ukraine on the higher aquatic and amphibic vegetation.

Water-cooling reservoir. To conduct the influence of specific conditions of water-cooling reservoirs on the higher aquatic and amphibic vegetation. A common technique of biology researches, statistics methods. Floristic structure is under analyses, interdependence of floristic structure with hydroochemical indices is defined and an ecological analysis is conducted. Some forms of plants that are not characteristic for the given region were registered. The role of communities in vegetable cover is analyzed. It is revealed that thermal condition influences changes in the coming of phonological phases and leads to the excessive spread of water plant groups and to the increase of morphometrical indices and phyto mass. These processes lead to the rise of biogenic substances and influence all stages of water ecosystem in the negative way. They interfere the normal operation of cooling machines at electric power station. The recommendations are given to provide the most optimum use of water-cooling reservoir.
