Study on COD Emission Reductions Assignment of Basin Based on Information Entropy Method and Gini Coefficient Method

Abstract:

The Qinghe and Fanhe basin in Tieling, Liaoning were studied as case in this sduty. The COD emission reduction was assigned by the method of information entropy and the Gini coefficient method first. Then the correlation between the calculation methods and the water environmental quality was analyzed. Finally, the best method of reduction calculation was identified. The results showed that the information entropy method was a better method in total allocation because it was highly correlated with water environment quality,at the same time it combined the pollution reduction and water environment quality management better. The results also showed the COD reduction in Qinghe basin was larger than Fanhe basin, so the Qinghe basin was the focus of emission reduction. Key words: Information entropy method;Gini coefficient method;COD emission reduction assignment;Correlation
