- 摘要:
- 在对2004年门楼水库相关水质指标进行监测的基础上，以叶绿素a（Chl a）、总磷（TP）、总氮（TN）、高锰酸盐指数（CODMn）和透明度（SD）等表征富营养化的指标作为评价因子，对门楼水库富营养化进行了现状评价和原因分析。结果表明，整个门楼水库处于中营养状态，总氮的污染分担率达39.2%，从而得出总氮是引起水库富营养化的主要污染物，而面源污染是造成水库总氮超标的最主要原因。最后提出了治理门楼水库富营养化的对策。
- Abstract:
- Based on the measures of water quality index in Menlou reservoir in 2004,the indexes of chlorophyl-a,total phosphorus,total nitrogen,permanganate value and transparency,which were as the tokens of water eutrophication,were used to evaluate and analyze Menlou Reservoir water eutrophication by means of quantitative analysis.The results showed that the entire Menlou reservoir was in the state of medium nutrition,the pollution rate of the total nitrogen shared in 39.2%,thereby the total nitrogen was the most dominating polluter.Furthermore,the cause of the pollution leading to the reservoir eutrophication had been found,the leading pollution source was surface source pollution.Finally,the countermeasures of controlling Menlou Reservoir eutrophication were put forward.
