Water Quality Analysis of Dishui Lake in the Reclamation of Beach Land

Man-made Dishui Lake which is excavated in the reclamation of beach land began to be perfused in Mar.2003.To assess its earlier ecological condition,this study analysis monthly data samples from the lake between Mar.2008 and Feb.2009 to investigate the changes in water quality,and evaluate the nutrition level of the water body.The results are followed by average transparency of year(40.7 ± 8.3) cm,DO(10.09 ± 2.32) mg/L,TN(2.765 ± 0.629) mg/L,and TP(0.336 ± 0.108) mg/L.Compared with the data earlier years’,the lake is in the condition of medium eutrophication comprehensively.And some practical and rational proposals were given.
