| 摘 要： | 基于2006年2月、5月、8月、11月胶州湾东北部养殖海区现场调查结果,采用单因子指数、富营养化指数、有机污染指数对环境状况进行了分析评价。结果表明:该海域主要受到无机N、P污染;COD在夏、秋季符合一类,但在冬、春季只达到国家二类海水水质标准;DO全部符合国家一类海水水质标准。通过站位间的比较发现,东北部沧口水域环境质量最差,全年处于富营养化状态,有机污染介于轻度到严重污染之间。红岛附近水质较好,不存在有机污染,只有春、秋季达到富营养化水平。研究结果显示该海域主要受陆源污染,且与现有污水处理不能有效去除无机N、P营养盐有关。 |

| Abstract: | Based on seasonal investigation data from the northeast mariculture zone in Jiaozhou Bay, the quality of seawater was evaluated with single factor evaluation, eutrophication index and organic pollutants index. Seawater was seriously polluted by dissolved inorganic nitrogen and phosphorus all through the year. However, concentration of dissolved oxygen (DO) was found to be higher than the 1st class concentration of Chinese National Seawater Standard throughout the year, while that of COD was higher than 1st class concentration in summer and autumn but only higher than 2nd class concentration in spring and winter. Seawater quality was worst near the Licun River estuary, where eutrophication was observed in all seasons and organic pollutants indices varied from slight to heavy pollution. No organic pollution was found near the Hongdao Island area, and eutrophication was observed only in spring and autumn. It was suggested that environment quality in this area was influenced mainly by land-source pollution, correlating to different removal efficiency of organic and inorganic materials during sewage treatment. |
