| 摘 要： | 根据2001~2004年6月与8月调查资料,阐述了辽东湾海域水体各化学要素的空间分布规律,并对辽东湾北部海域夏季的综合水质状况,海域营养结构及营养水平进行了评价。结果表明:各化学要素的空间分布趋势基本为近岸高于远岸,主要的污染区域集中在大凌河口与双台子河口海域。主要的污染因子氮、锌、铅和油。2001~2004年间,2002年该海域为严重污染,其它年份为中污染;氮磷比率偏高并逐年上升;整个海域一直处于磷限制潜在性富营养状态。 |
| 关 键 词： | 辽东湾 水化要素 空间分布 综合评价 |

| Abstract: | Based on the datum line survey in June and August from 2001 to 2004,the spatial distributions of chemical elements in the seawater of Liaodong Bay were described and comprehensive assessment of the water quality,nutritive structure and nutritive level were anlyzed,respectively.The spatial distribution trends of the chemical elements decrease from inshore to offshore,the main polluted factors were nitrogen,zinc,lead and oil and the most contaminated areas were the sea areas of Daling Eastuary and Shuangtaizi Eastuary.From 2001 to 2004,the polluted level was medium,but surious pollution was in 2002;the rates of nitrogen and phosphorus was in increasing and the whole area was in potential phosphate-limiting eutrophication. |
| Keywords: | Liaodong Bay chemical elements spatial distribution comprehensive assessment |
