Gogol O. Geoecological basis for the protection and sustainable use of biological resources of the Pechenigy reservoir

The object of the study is the effect of natural and natural-anthropogenic complexes of the water basin of the Pechenigy reservoir in the Kharkiv region on its biological resources and the development of ways to optimize the use of natural resources. The purpose : development of events to optimize the use of natural resources in the basin of the Pechenigy reservoir to improve biological productivity on the basis of its integrated geo-ecological assessment. Methods: constructive-geographic methods that are complemented by a complex of general scientific (analysis, synthesis, comparison, generalization), and special (historical-geographical, cartographic, mathematical modeling, geoinformation, landscape-ecological) methods, biological resources are assessed by a set of biological methods. Scientific novelty: complex physical and geographic assessment of Pechenigy reservoir basin has been carried out and relevant cartographic works have been developed;- geochemical survey of the territory of the basin has been completed with further calculation of landscape-ecological indexes and construction of the corresponding cartographic model; the dynamics of industrial fish quantity has been analysed for the whole period of the reservoir functioning and the factors determining it have been determined; a cartographic model of the basin’s nature use optimization has been developed, containing a set of measures to improve the environmental situation in the reservoir. The results can be used in developing measures for the conservation of biological diversity in the reservoir of Ukrainian
