Abstract

Six sampling stations were selected at Jinhe River and Seven water quality parameters were measured which include transparency、chromaticity、Dissolve Oxygen(DO)、Chemical Oxygen Demand(COD_(cr))、Biology Oxygen Demand(BOD_5)、Total Phosphorus(TP) and Total Nitrogen(TN).The results showed that transparency、chromaticity and DO were in accordance with the water standard of landscape and amuse,but COD_(cr)、 BOD_5 、TP and TN were all higher than standard and the water has emerged eutrophication.Finally,according to the characteristics of Jinhe River and the origin of the pollutants,some good suggestions on the water quality maintaining were made.
