五元系数法-改进熵权法在水质评价中的应用
Application of five-element connection number method-improved entropy method in water quality evaluation
摘要
Abstract
To tight the relationship between the water quality monitoring value and water classified standard, the five-element connectionnumbermethodwasusedtoestablishthefive-elementconnectionnumbersoftheevaluationcriteriaforvariousindi-cators of water quality evaluation.On the basis of traditional entropy weight calculation,the rank method was used to set the preference correction coefficients and then to obtain the improved entropy weights.The five-element connection number ui was combinedwiththeimprovedentropyweightWRitoobtainthecomprehensivefive-elementconnectionforwaterqualityevalua-tion.Thisisanewlycombinedobjectiveandsubjectivemethodforwaterqualityevaluation.Themethodwasappliedtoevaluate water quality grade and analyze the variation trend of water quality in a river of Guiyang City of Guizhou Province based on the monitoring data of a cross section,which verified the applicability of the five-element connection number method-improved en-tropy method in water quality evaluation.关键词
