The diatom analysis of the reservoirs located on the Kalmius River

The paper examines biodiversity of diatoms in artificial reservoirs the Kalmius river basin, as well degree impact industrial enterprises on water resources by bioindication. author has established current state balance rivers, and use industry Donbass. Thus, is formed due to a part inflow from Seversky Donetsk basin waters main River basin. Agriculture total consume 77% entire region, which an extremely high involvement overall resources. To assess condition reservoirs, method determining species diversity biological analysis DAIpo was chosen. As study, it found that flora according ShannonWeaver index varied 1,98 4,65 bps, while only 11 were massively distributed reservoirs. coefficient growth (r) varies (from 0,2135 0,9522 bps) depending season year place selection. It increase occurred during transition Nizhnekalmius reservoir Starobeshevsky reservoir, presence larger number saproxene Achnanthes andicola, Fragilaria virescens, Navicula viridula var. viridula. Nitzschia sigmoidea sigmoidea, radiosa radiosa. Consequently, traces level pollution indicator tolerance environmental conditions.
