| 摘要: |
| 应用系列综合评价法对吕四渔场生态环境质量进行了试探性分析评价研究。NQI值法分析结果表明，吕四渔场持续处于富营养化状态或中营养化状态下。A值法分析结果表明，渔场有机污染处于轻度和中度污染状态；重金属评价结果表明，部分站位Cu、Zn和Hg处于污染状态，Pb、Cd和As在自然本底值范围内；综合评价结果表明，吕四渔场环境质量状况大部分时间处于较差状态。因此，其生态环境质量有待改善。 |

| Abstract: |
| The ecological environmental quality of Lüsi fishing ground of Jiangsu Province was analyzed by integrated assessment methods. The results of NQI's assessment showed that Lüsi fishing ground was at eutrophication or medium nutrition level, and A value analysis showed slight or medium organic pollution all through this fishing ground. Contents of heavy metals, including Cu, Zn and Hg were above the standard limit at some sampling sites; while contents of Pb, Cd and As were within the range of natural background value. Analyzed by integrated assessment methods, the eco environment quality of Lüsi fishing ground was relatively poor most of the time, and calls for improvement. |
