芜湖市镜湖水体富营养化特征分析及生态修复探讨
- Title:
- The Eutrophication Characteristic Analysis and the Control Countermeasure of Jinghu Lake in Wuhu
- Keywords:
- Jinghu Lake; pollution; eutrophication; ecological recovery
- 分类号:
- X524
- 摘要:
- 通过实地监测,系统分析了清淤近6年后的镜湖水质状况.研究结果表明:水体溶解氧含量丰富,适合鱼类生长,但化学需氧量(COD)、总磷(TP)、总氮(TN)、叶绿素a(Chla)等已超标.对单项污染指数((Ii)与卡尔森富营养化指标(TSI)的测算和评价都表明镜湖水体已成富营养化态势.在此基础上,提出了从污染源控制及生态修复等对镜湖富营养化控制.
- Abstract:
- By on-the-spot monitoring,the Jing Lake water quality conditions after 6 years silt settlement are analyzed systematically.The findings indicate:the rich DO content of the water body fits fish growth,but the chemical oxygen demand(COD),the total phosphorus(TP),the total nitrogen(TN),chlorophyll a(Chla) and so on exceed the allowed figure seriously.Single Item pollution index(Ii) or Carlson’s Trophic Status Iindex(TSI) surveys with the appraisal all indicates the Jing Lake water body is at eutrophication.On this basis,the control countermeasure is proposed.
