摘要：

[目的]评价江苏启东贝类增养殖区的环境质量。[方法]根据2016年对启东市贝类增养殖区海域环境4次监测结果,对贝类增养殖区环境状况进行了系统地分析和评价。并采用单因子指数法、有机污染评价指数法、富营养化指数和内罗梅水质综合指数法对该养殖区域水环境进行评价。[结果]启东贝类增养殖区水质有超标现象,超标污染物有无机氮(DIN)、活性磷酸盐(DIP),超标率分别为22.7%和23.3%;沉积物各项指标均符合一类标准;贝类中超标污染物为Pb,超标率达48.0%。[结论]该养殖区水质为清洁水平,水质呈富营养化状态。

摘要：

[Objective]The study aimed to evaluate environmental quality of shellfish aquaculture areas in Qidong,Jiangsu. [Method]Based on 4 times monitoring data in 2016 in shellfish aquaculture area of Qidong,a systematic analysis and evaluation on the environmental conditions of shellfish culture areas were carried out. The seawater environment in aquaculture areas was evaluated by using the single-factor assessment,the ecaluation indices of organic pollution,the ecaluation indices of eutrophic and the nemerow's index. [Result]The results showed that the seawater quality of Qidong shellfish aquaculture area exceeded the standard,the exceed standard pollutants were DIN and DIP,the over standard rate were 22. 7% and 23. 3%. The index of surface sediments were in accordance with sediment standard grade Ⅰ. The exceed standard pollutants in shellfish was Pb,the over standard rate was 48. 0%. [Conclusion]The water quality of the aquaculture area was clean and the water quality was eutrophic.
