摘    要:目的]为了了解安吉县赋石水库流域内河流水质状况。方法]2010年7月对该流域河流中15个点进行监测取样,采用室内测试分析和模糊数学综合分析法,分析了各测点DO、CODMn、NH4+-N、TN和TP 5项指标。结果]构建了评价因素和评价等级的论域,计算了各监测点评价因子的关系矩阵,确定了监测因子的权重,并采用模糊数学综合评价法对各监测点的水质进行了评价。评价结果表明该流域河流水质为V类水,主要污染物为CODMn和TN。结论]2010年7月以后该流域水质出现恶化,主要污染因子为CODMn和TN,需要加强对面源污染的管控。

关 键 词:模糊综合评价  监测因子  水质  评价  赋石水库流域

Abstract: Objective ] To understand water quality of Fushi reservoir watershed rivers in Anji County. Method ] 15 monitoring points in rivers of Fushi reservoir watershed were monitored in July 2010, using indoor test analysis and fuzzy comprehensive analysis, 5 indicators of DO, CODMn, NH4+ -N, TN and TP were analyzed. Result] The domain of evaluation factors and rank was established, the relation matrices of evaluation factors in each monitoring site were calculated, the weights of monitoring factor were determined. The water quality of every monitoring point was evaluated by the fuzzy comprehensive evaluation method. The evaluation results showed that the water quality of rivers in Fushi reservoir watershed was grade V, and the main pollution sources were CODMn, and tiN. Conclusion] After July in 2010, the water quality has degraded by the CODMn and TN, so it is necessary to strengthen management and control of the non - point source pollution.
Keywords:Fuzzy comprehensive evaluation  Monitoring factor  Water quality  Evaluation  Fushi reservoir
