| 摘 要： | 在2009年对西津水库水质进行了4次监测。参照中国湖泊水库富营养化评价标准,将富营养化程度分为6个级别,应用灰色聚类法,选定高锰酸盐指数（CODMn）、总磷（TP）、总氮（TN）、叶绿素a（Chl-a）、透明度（SD）为聚类指标,对西津水库米埠坑库区水质富营养化程度进行评价。结果表明,米埠坑库区上游水质为中营养化,库区中下游水质已处于中富营养化;该库区水质有富营养化趋势。

| Abstract: | Water quality monitoring of Xinjin reservoir was carried out for four times in 2009.Eutrophication degree was divided into six levels (four gray classifications) according to eutrophication standard of Chinese lake and reservoir.CODMn,TP,TN,Chl-a,SD were selected as clustering indicators.Eutrophication of Mibukeng in Xijin Reservoir was assessed with the Grey Clustering Method.The results showed that water quality of Mibukeng’s upstream was mesotrophic,and water quality of midstream and downstream in Mibukeng was upper-mesotrophic.Eutrophication of the reservoir’s water quality trended. |
