ASSESSMENT OF ECOLOGICAL SAFETY STATE OF THE KREMENCHUK RESERVOIR AQUATORIUM FOR THE PRESERVATION OF LANDSCAPE-BIOLOGICAL DIVERSITY IN CLIMATE CHANGE CONDITIONS

Abstract

Purpose. The problem of preserving the landscape-biological diversity and ecological safety of fresh waters of the reservoirs of the Dnieper cascade is quite relevant due to its growing deficit in the face of climate change. In reservoirs, the coastline is eroding, causing changes in natural landscapes. Almost everywhere, fresh water pollution is growing and becoming more diverse, as a result of which water becomes unfit not only for drinking or the existence of aquatic organisms, but also for technical purposes. When determining the need for water, it is also important to take into account the own needs of aquatic ecosystems in the water quantity and quality. Fresh water is the most important component of nature with a high rate of biodiversity. It is a medium-higher habitat for many species of living organisms, both aquatic and semi-aquatic, providing purity and self-restoration of surface water quality. Fresh water ecosystems are closely linked to terrestrial ecosystems by thousands of different connections that ensure balance in nature. Therefore, biodiversity conservation is important. Methodology. The research was performed using phytoindication, the method of determining the anatomical and morphological changes of plant indicators. Results. The state of ecological safety of surface waters was assessed using indicators of anatomical and morphological changes of indicator plants, which allow drawing conclusions about the resistance of the ecosystem to harmful factors, as well as the need for additional, more accurate physicochemical studies. The object of the research is the Kremenchuk reservoir, the largest among the reservoirs of the Dnieper cascade. The ecological danger formed in it extends both to the coastal part of the water area and reaches the Black Sea. It is the need for additional physical and chemical tests to accurately identify sources of impact on the water of the Kremenchuk reservoir near the Svitlovodsk and further development of measures to ensure the ecological safety. Originality. For the first time is conducted a study of the ecological safety of the Kremenchuk Reservoir waters by the phytoindication method. According to this study, is demonstrated the effectiveness and simplicity of environmental monitoring using bioindication methods. Practical value. According to this study, we demonstrate the effectiveness and simplicity of environmental monitoring using phytoindication methods. References 14, tables 1, figures 3.
