Geoecological State of Bistriza-Tlumach’s And Prydniester-Pokutskiy Highlights

Abstract

Abstract. The anthropogenic environmental changes over the past decade have become global for the entire globe. They deeply penetrate into all components of the environment - the lithosphere, the geomorphosphere, the hydropower and the atmosphere, the soil and vegetation, alter the physical fields of the Earth and the Cosmos, transforming the original natural landscapes into natural and human-made geosystems and endangering human health and life. Especially sensitive to changes are the least protected natural landscapes on the territories of the nature reserve fund - natural monuments, nature reserves, regional parks, national natural parks, natural and biosphere reserves. The article deals with the issues of technogenic influence on the part of the territory of the Dniester Regional Landscape Park - Bistriza-Tlumach’s and Prydniester-Pokutskiy hills of the Prut-Dniester interfluve in Ivano-Frankivsk region. The authors carried out an ecological assessment of the environmental components of the specified territory - geological environment, relief, hydro- and atmosphere, soil and vegetation cover. Recommendations on the reduction of anthropogenic influence by introducing geoinformation technology of environmental protection, its modeling and forecasting are offered. Most of the study area has a generally normal ecological status. There are favorable conditions along the Dniester Canyon, where the oxygen content in the atmospheric air is higher than the average. Within a short distance of the Dniester Canyon from the north-west to the southeast, lanes of satisfactory condition stretch. Within them, five sites of complex ecological status have been identified. The comparison of the obtained data of the ecological assessment of the heights on the right riverside with the adjacent territory on the left riverside of the Dniester – located there National Nature Park “Dniester Canyon” showed that practically all geo-ecological structures of the right bank have their continuation on the left riverside. It follows that the Dnistrovsky Regional Landscape Park should be transferred to the category of nature reserve fund “National Nature Park” and be combined with the National Park “Dnistrovsky Canyon”.
