title: [Application of fuzzy comprehensive assessment in risk assessment of water pollution conditions in downriver area of Dahuofang reservoir].
abstract: Fuzzy comprehensive model was used to assess water quality state in Hunhe river of Dahuofang reservoir from 1996 to 2004. It was found that the water quality of Hunhe river changed fluctuantly and belonged to II and serious III state besides in 1997, 2001, and 2003. The main pollutants were organic pollutants, oil and ammonia. Concentration of oil and ammonia gradually increased from 1996 to 2004, and COD changed irregularly, while BOD5 decreased.
