Using Fuzzy Theory for Analyzing Ten-year Water Quality Variational Trend of Er-longshan Reservoir
This study used fuzzy theory for analyzing ten-year water quality variational trend. CODMn, BOD5, TN and TP were selected as main contamination factors taking related factors into account. It was found that the primary pollutants were nitrogen and phosphorus by calculating weight coefficient ei of contamination factors from 1996 to 2005. It shows Er-longshan reservoir belongs to organic pollution type. According to fuzzy comprehensive exponent zj evaluating water quality of reservoir from 1996 to 2005 separately, the ten-year water quality dynamic trend was studied. The results showed both setting up tour resort in 1999 and honored as national 4A tour resort in 2000 were responsible for descending trend of water quality. These 3 years, the water quality was looking up. We concluded that the integrative treatment of pollution points, resource protection and carrying out ecological agricultural methods had active action in water quality protection of Er-longshan reservoir.
