| 摘 要： | 参照湖泊富营养化评价标准,选取高锰酸盐指数、总氮(TN)、总磷(TP)、叶绿素a(Chla)、透明度(SD)5个评价指标为聚类指标,采用灰色聚类法对珊溪(赵山渡)水库6个监测点的2011年3-8月监测数据进行富营养化评价。结果表明:黄坦坑为5级富营养,主要受畜禽养殖废水影响,其余交溪口、百丈口、珊溪大坝、支坑和赵山渡5个监测点为4级中富营养,出现了富营养化趋势。6个监测点富营养化程度由重到轻的顺序为:黄坦坑>交溪口>百丈口>珊溪大坝>支坑>赵山渡。在对评价结果的分析探讨基础上,提出了水质改善及富营养化防治对策。

| Abstract: | According to the lake eutrophication evaluation criteria,COD,TP,TN,Chla and SD were chosen as clustering indices.Gray clustering method was applied to evaluate the eutrophication degree of Shanxi(Zhaoshandu) reservoir.The clustering result indicated that the Huangtanken belonged to fifth level eutrophic,mainly by the influence of the wastewater from livestock farm,Jiaoxikou,Baizhangkou,the orther of 5 monitoring point include Shanxi dam and Zhaoshandu belong to fourth level eutrophic.The result appeared the trend of eutrophication.The eutrophication of 6 monitoring points from light to heavy order: Huangtanken>Jiaoxikou>Baizhangkou>Shanxi dam>Zhaoshandu.On the basis of the evaluation analysis,the countermeasures against eutrophication were put forward. |
