| 摘要: |
| [目的]研究分析独墅湖的水动力和水质状况。[方法]采用现场调查的方法,对独墅湖枯水期多个测点的水动力和水质状况进行取样分析。[结果]独墅湖水面坡降、水流流速和进出湖流量都非常小,不利于污染物质随水流排出。水质方面总磷(TP)、总氮(TN)和化学需氧量(CODMn)等因子含量高的水域溶解氧(DO)含量低而叶绿素a含量高,反之亦然。[结论]受周围河网影响,独墅湖水体中TP和TN含量非常高,已属于富营养化,需要对进出湖污染物和过度养殖的影响进一步研究,为采取相关措施改善独墅湖水质提供参考。 |

| Abstract: |
| [Objective] Investigation on hydrodynamics and water quality in the Dushuhu Lake.[Methods] The research on hydrodynamics and water quality statuses of several monitoring spots in the Dushuhu Lake was studied.[Results] Data show that water-surface gradient,flow velocity and flux of in-and out-lake are all very small,which is difficult for the pollutant discharge.In the aspect of water quality,low DO concentration and high chlorophyll-a concentration appears in the water area where the concentrations of TP,TN and CODMn are high,and vice versa.[Conclusion] Affected by around rivers,the high concentrations of TP and TN in the Dushuhu Lake shows that it becomes a eutrophic lake.It is necessary that the effects of pollutant and over culturing are studied in order to provide reference for improving water quality of the Dushuhu Lake. |
