ASSESSMENT OF THE CONDITION OF WATER ECOSYSTEMS OF THE CENTRAL CHERNOZEM REGIONON THE BASIS OF THE ANALYSIS OF RESTRUCTURINGS OF COMPLEXES OF MICROALGAS
Article contains results of an assessment of an ecological and biological condition of the Voronezh and Matyra reservoirs, the lakes Ramza and Kipets. The analysis of restructurings of complexes of microalgas and cyanobacteria of water ecosystems at the Central Chernozem Region is carried out by means of methods of taxonomical proportions and the linear transformations. The graphic analysis allowed to confirm the conclusion drawn earlier by the author about selection of three sites in the Voronezh reservoir and crisis state of lower site. Restructurings of complexes of microalgas and cyanobacteria of the Matyra reservoir demonstrating that the algolization promotes improvement of an ecological and biological conditions of a reservoir, inhibiting intensive development of cyanobacteria. However the effect of these actions is short. The graphic analysis revealed transformation of the lakes Ramza and Kipets in connection with change of natural and anthropogenous conditions.
