【 摘 要 】

The research results of plankton biocenoses in the Kharanorskaya TPP cooling pond in different temperature conditions are presented in paper. The species diversity of hydrobionts in the heated zone is higher compared to the unheated one. The dominant complex of plankton community in the two thermal zones is similar and includes species with a high temperature optimum. The absence of significant differences in the spatial-temporal dynamics of plankton quantitative indicators is associated with the morphometric features of the reservoir and the mechanical factors influence. The main abiotic factors influencing the distribution of hydrobionts are the water chemical composition in the unheated zone, and are hydrochemical and hydrophysical parameters in the heated zone.
