| 摘 要： | 利用模糊综合评判方法对2009年辽河口湿地的水环境质量进行了综合评判.17个样点的监测结果显示,7月份辽河口湿地水质大多数样点化学需氧量(COD)和全氮(TN)超地表水环境质量IⅤ类标准,全磷(TP)、氨氮(NH3-N)和重金属(Cd、Pb、Cu、Zn)优于III类标准.运用统计学方法从8个监测指标中遴选出了COD、TN、TP、NH3-N、Cd和Pb 6个指标作为参评因子,采用污染贡献率方法确定单因子权重系数,评判结果表明辽河口湿地大多数样点水质级别为Ⅴ,水环境质量较差.

| Abstract: | Water quality of Liaohe River estuarine comprehensive evaluation method. The examined wetland in July 2009 was evaluated based on fuzzy results of 17 water samples showed that COD and TN concentrations of most samples exceeded class Ⅳ of Environmental Quality Standards for Surface Water, and TP, NH3 -N and heavy metals including Cd, Pb, Cu and Zn better than class Ⅲ. Except for Cu and Zn, six factors were selected to be evaluated from all examined index by statistics method. The weighting coefficient for each factor was calculated by its pollutant contribution to water quality. Fuzzy comprehensive evaluation results showed that water quality grade of the most samples was Ⅴ and water environment quality was bad. |
