摘　　要：为准确反映渭河水质现状,应用均值化灰色关联分析法,选取BOD5、CODCr、CODMn、NH3-N、TP、TN、氟化物等7个水质监测指标对2008—2009年渭河宝鸡段监测断面水质进行评价。结果表明,各主要断面总体水质良好,其中虢镇桥、蔡家坡桥的水质较差,为Ⅳ类水质。渭河宝鸡段区域性的污染随时间、空间不断变化。采用均值化灰色关联分析法,具有计算较简便,可操作性好,更符合实际情况的特点,对渭河宝鸡段水质评价效果良好。To make an accurate assessment of water quality, seven water quality monitoring indicators including BOD5, CODCr, CODMn, NH3-N, TP, TN and content of fluoride in Weihe River Baoji section from 2008 to 2009 were evaluated based on equalized grey correlation analysis. The results showed that the overall water quality of Weihe River Baoji section was good. Water quality of Guozhen Bridge and Caijiapo Bridge were at grade IV, which was poor. Regional pollution changed with time and space. The equalized grey correlation analysis, which was simple, actual and easy to operate, had good effect on water quality assessment in Weihe River Baoji section.
