Assessment on the Pollution and Eutrophication of Environmental Water by HydrobIologica

The water pollution and eutrophication were judged by the assessment of hydrobiology with the species and quantity measure and analysis of phytoplankton,zooplankton,bottom dwelling biology and fish.Combined with the aqueous chemical parameter such as TN,TP and COD,the monitor and assessment of environment water pollution from hydrobiology could reflect environment water quality objectively and synthetically.This paper introduced several hydrobiologica ways which assessed water pollution and eutrophication,referred to main factors affecting assessment target,and provided reference with direct,quick and correctly judging water pollution and eutrophication.
