摘要
Abstract
In order to explore an objective and reasonable water quality evaluation method,this article combined information Entropy with comprehensive water quality identification index method,and applied in Haihe river (six national monitoring stations) in July 2010 to 2011 June.Compared with traditional methods,this method fully excavated information of various indexes monitoring data in entropy weight calculation and comprehensive water quality identification index calculation,making the evaluation result more reasonable.The results showed that (1) the water quality of six monitoring points met the water target function in Haihe River during July 2010 to 2011 June,but the space differences and seasonal fluctuation for specific water quality were still existed; (2) combined with colleague's research,results showed that the Haihe river water quality have improved generally,reflecting the related policies and measures were reasonable and practicable to improve the water quality of Haihe river in recent years.关键词
