By mean of the potential eutrophication assessment model,the eutrophication grade in Xiangshan Harbor was assessed.

Based on 12 cruises of observed nutrient data in the Sanggou Bay during August 2003 to July 2004,the distribution characteristics and variabilities of nutrients in seawater of the sea area are analyzed,and the potential eutrophication conditions of water quality are assessed.

Finally,potential eutrophication of Liaodong Bay was assessed.

2007,the analyses on the change trend and evaluation of eutrophication degree in the waters were made with the potential eutrophication grade standards and corresponding evaluation model.

Unascertained parameter-based method for lake eutrophication assessment

Considering the characteristics of the study on ecological environmental, the Eutrophication Assessment Models which base on the fuzzy theory and neural network theory which developed made our group were standar

It is concluded that the new method is feasible for the determination of the discrepancy coefficient i and lake eutrophication assessment.

Research of eutrophication evaluation and the countermeasures for urban lakes can provide scientific foundations for water environment protection and improvement.

According to the water quality monitoring results of Wensi Lake in the past years,the evaluation of water quality was made by using single-index evaluation method,the Windex evaluation of the synthetic evaluation,eutrophication evaluation and comprehensive evaluation of organic pollution.

Application of unascertained measure model based on entropy weight to evaluation of eutrophication of lakes and reservoirs;
