Методика интегральной оценки трансформаций водных экосистем

Abstract

The results of a research of neopleistocene and modern water ecosystems of the center of the East European Plain are given. Regularities of change of taxonomical proportions in communities of phytoplankton and a microphytobenthos when changing natural and natural and anthropogenic conditions are revealed and parameters of environmental standard of their distribution are determined. The revealed communications between change of ecological and biological characteristics both natural and natural and anthropogenic influence are the basis for a technique of integrated assessment of transformations of water ecosystems. Threshold sizes of indicators of a water ecosystem are determined, they reflect its transition from one state to another and also change of level of load of it. Modernization of a method of graphic comparison of taxonomical proportions in communities of phytoplankton and a microphytobenthos is carried out that allows to expand the field of its application.
