| 摘 要： | 根据 1999-2006 年 6-8 月的调查数据,分析辽东湾北部海域的营养水平及变化趋势,以了解辽东湾北部海域营养水平的分布特点及污染状况.由 E 值和 CN/CP 值的总体评价结果来看,辽河口、双台子河口和大凌河口海域的富营养化程度较高,属于磷中等限制潜在性富营养区,而锦州湾海域污染相对较轻,属于中度营养区;在时空分布上,辽东湾北部海域 1999 年与 2006 年污染较为严重,中间年份污染相对较轻.针对辽东湾的具体环境用 CN/CP 值的评价模式更能揭示出营养盐限制对富营养化的影响.

| Abstract: | Based on the data from the investigation from June to August during 1999 to 2006, we analyzed the nutrient level and changing trend in the north sea area of the Liaodong Bay to clarify the distributing Characters and pollution status. From the eutrophication index E and CN/Cp value, it concludes that the eutrophication degree is high in the Liao River, Shuangtaizi River and Big Ling River estuary area, and this area can be classified as a phosphate-limiting moderate-level nutrient area, and the eutrophication degree is low in the Jinzhou Bay area which can be classified as a moderate-level nutrient area. For the space-time distribution, the E of the north sea area of Liaodong Bay in 1999 and 2006 is high, but it is equable in the middle years from 1999 to 2006. And the nutrient-limiting influence on the eutrophication can be opened out better from the assessment of the CN/Cp value. |
