Bioindication of Belgorod and Stary Oskol Reservoirs State With Phytoplankton (Belgorod Oblast, Russia)

Abstract

The aim of present article is description of the artificial water bodies of Kursk Magnetic Anomaly (KMA) within Belgorod oblast for justifying criteria of assessment of ecological state of surficial waters under technogenic stress. Methods. Assessment of ecological state of Belgorod and Stary Oskol reservoirs was conducted by computation of saprobic index and correlation between taxonomic and ecological assemblages of phytoplankton. Analysis of spaceborne images of Terra ASTER was applied for composing maps of actual material. Results and discussion. State of water ecological systems is dependent on technogenic influence of water sheds, which predefines assemblages of microalgae and Cyanobacteria. Ecological quality of waters emerges distribution of species of Cyanobacteria related for polluted environments. Spatial analysis of spaceborne images of water suspensions and turbidity was done for water areas of Belgorod and Stary Oskol reservoirs. Conclusions. Conducted research was used for detecting of water quality with phytoplankton under technogenic tension. Derived distributions of suspensions and turbidity are necessary for justification of criteria of assessment of water bodies ecological state. They could be used as reference background date in case of water bloom.
