摘要
2009年5月7日到11日在天津汉沽海域进行了海上实际调查,通过采集样品的分析检测,掌握海域环境状况。根据所获资料分析了海水理化指标、叶绿素a和浮游植物的含量及分布特征。结果表明,海域各指标含量离岸递减,近岸高外海低,并且海域环境东部优于西部。同时运用N/P、单因子分析、富营养化指数、有机污染指数、生物评价法分析了汉沽海域环境质量,结果表明汉沽海域环境质量已经受到污染,应加强治理。
The Marine investigation of Hangu sea area was carried onMay7,2009 to May 11.Through makes the laboratory examination to the sea water sample,has analyzed Physical and chemical indicators of water、chlorophyl a and Phytoplankton.The result indicated that,each factor distributed characteristic is its density equivalent line decrease progressively to the shore,the nearshore high and open sea is low,and the Marine environment of east sea area better than the west,wo also analyze the Marine Environmental Quality through the N/P、Single-factor analysis、Trophic state index、Organic Pollution Index and Biological Evaluationsea,The results show that water quality of Hangu sea area has been contaminated,governance should be strengthened.
