Abstract

A method for quantitative assessment of multifactor impacts on freshwater ecosystems has been developed. The method uses the general regularities of technogenic succession in reservoirs that we have established. At the same time, macrozoobenthos turned out to be the best indicator of the state of aquatic environment, biotic and anthropogenic changes in the ecosystem. Its parameters are recognized as the main ones for assessment of external load on reservoirs. The universal dimensionless parameter Y, which expresses the proportion of exceedance of community stability, serves as a measure of impact. This parameter is taken into account on the basis of the original isobolic model. For the first time it allows to adequately take into account the effect of interaction of limiting factors of any nature and in any quantity. This ensures high accuracy of the assessment. Maximum permissible levels of complex impacts are determined. A unified quantitative approach to rationing and regulation of multicomponent technogenic load on hydro-ecosystems is given.
