摘  要：
选取南关桥、北关桥、东关桥、西关桥4个监测点,采用单因子指数、内梅罗指数及综合营养状态指数法对东昌湖2011年水质状况和富营养化程度进行了分析。结果表明,东昌湖各监测点夏季pH、CODCr及TN的含量较高,DO及TP含量夏、秋季较高,其中pH、DO、CODCr单因子指数基本满足Ⅳ类水质标准;TN单因子指数呈先上升后下降趋势,以7月较高;TP单因子指数总体呈上升趋势,以11月较高。内梅罗指数在调查年度内总体呈上升趋势,TP、TN对东昌湖水质影响较大。从富营养化评价结果来看,东昌湖富营养化指数以夏季最高,其中南关桥>西关桥>北关桥>东关桥。

摘  要：
Water quality situation and eutrophication degree of Dongchang Lake in 2011 were analyzed based on the four monitoring points of Nanguan Bridge,Beiguan Bridge,Dongguan Bridge and Xiguan Bridge by single factor index,Nemerow index method and trophic state index method.The results showed that in the monitoring points of Dongchang Lake,pH,CODCr and TN content was high in summer;while DO and TP content was high in summer and autumn;pH,DO and CODCr nearly met IV class standard;TN single factor index increased first and then decreased,reached the top in July.TP single factor index showed an increasing trend and was high in November.Nemerow index showed an upward trend during the investigated years.TP and TN had great impact on water quality of Dongchang Lake.Furthermore,According to the eutrophication assessment,eutrophication index of Dongchang Lake was the highest in summer,and the sort of monitoring points from high to low was Nanguan Bridge,Xiguan Bridge,Beiguan Bridge,Dongguan Bridge.
