Abstract
Purpose. The article aims to determine the structural and functional patterns of the development of naturally-technogenic systems on the example of the mouth of the Irpin River. Methodology. An ecosystem principle and a basin approach helped to study the Irpin's hydroecosystem. We chose a statistically- mathematical method of data processing. We used mathematical modeling to estimate the future damaging effect of man-made influences on the dynamics of changes in the indicators of hydrobionts' habitat. Results. It was investigated, that multifactor technogenic impact had caused the formation of ecologically dangerous risks in the development process of the naturally-technogenic sys-tem. It was confirmed, that technogenic impact determined the intensity of internal water processes and established optimal parameters for rational use of nature (IV class water quality - 1.1; V class water quality - 1.9). The case study also showed that the optimal mode of water use is characterized by low gradations of the average development risk of technogenically conditioned water systems and high criteria of biotic self-regulation mechanism. Originality. For the first time, homeostatic parameters of the naturally-technogenic system of the Irpin River were displayed. It was shown, that the change of homeostatic parameters of the naturally-technogenic system was due to the transformation of their primary structure, because of the formation of a balance of techno-capacity within the balance of environmental capacity. Practical value. The processes of homeostasis are ecological postulates that characterized the optimal parameters. It should be used as a benchmark for forecasting calculations, for the future development of the naturally-technogenic system. The structural and functional features of Irpin river hydroecosystem development in space and time were investigated. The definition of the combined anthropogenic influence has been characterized and substantiated by the following indicators: total or additive effects, effects of potentiation, effects of antagonism. Indicators that characterize the processes of self-healing of technogenically-conditioned water systems were established.
