摘　　要：应用灰色关联聚类分析法,对莱芜市牟汶河整治后的水质质量变化状况进行了综合评价。采用牟汶河寨子河桥断面2005~2008年的水质监测数据,选择具有代表性的四项指标作为评价因子。通过计算污染物权重,构造改进的白化函数,进一步计算出灰色关联度,依据《地表水环境质量标准》（GB3838-2002）通过理论阐述与计算,得出评定结果：2008年〉2007年〉2006年〉2005年。Gray relation method was applied to the comprehensive assessment of Muwen River water quality in this paper.This article took the water quality monitor data of Zhaiziheqiao section from 2005 to 2008,four represent guidelines was chosen as the evaluate factors.The water quality was assessed by calculating the weight of contaminant,constructing improved bright function,and then calculated grey relational grade,based on the ＂surface water quality standard＂（GB3838-2002） and through theoretical explanations,the result shows the water quality of Muwen River changed for the better after the river channel hardness projects.The result： 2008200720062005.
