Abstract: 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.
