摘要
以2008年8月在南四湖4个湖区的水质监测数据为基础,以叶绿素a、总磷、总氮、透明度和高锰酸盐指数为监测项目,采用综合营养状态指数法对南四湖进行富营养化评价。结果显示:南四湖已进入了营养化状态,其中南阳湖已达到中营养化程度。从天然和人为因素两方面分析在丰水期南阳湖产生营养化的原因,为富营养化的治理提供依据。
Referring to water quality monitoring data of Nansi Lakes in August,2008,the state of eutrophication was evaluated according to TSI method,with the indexes of chlorophyll.a,total phosphorus,total nitrogen,sheer degree and CODMn.The results show that Nansi Lakes have been in the state of nutrition,among which Nanyang Lake is mesotropher.The causes were analyzed from all aspects of the situation,which can provide a basis for the control of lake eutrophication.
