Abstract

Applying gray theory to variational trend evaluation of water quality of Xi-quanyan reservoir, COD_MN, BOD₅, TN and TP were selected as dominating contamination factors taking related factors into account. We found that the primary pollutants were nitrogen and phosphorus by calculation weight coefficient of contamination factors from 2000 to 2003. It means Xi-quanyan reservoir belongs to organic pollution type. According to fuzzy general exponent z_j evaluating variational trend of water quality of Xi-quanyan reservoir water from 2000 to 2003, we concluded that if Xi-quanyan reservoir was carried out the Ground Water III Criterion, the water quality would fall short of standard and the rate up to par couldn't reach 100%.
