Anthropogenic changes in water ecosystem on the example оf the river Tisza

Abstract

While conducting the ecological estimation of the hydro ecosystems (HE) condition of Tisza water basin, engineering ecological indices and their parameters are used. The system-basin research approach of the water basin based on systematization and data processing of the ecological monitoring for a long-term period is used. Such period allowed to set scientific regularities of naturally-anthropogenic hydro ecosystems development in the conditions of constant anthropogenic load on them.
