| 摘 要： | 根据2005-2011年春夏两季秦皇岛近岸海域主要环境因子的监测结果，应用单因子污染指数法和营养状况指数法对该海域海水质量以及富营养化程度进行了评价与分析，并初步探讨了与赤潮发生的关系。结果表明，秦皇岛近岸海域COD和无机氮一直维持在一定水平，磷是富营养化及赤潮发生的限制因子，赤潮多发区由北戴河西浴场附近向东浴场附近转移。大面积赤潮的发生导致海水中的营养盐被大量消耗而表现为春夏两季水体的营养指数较低。

| Abstract: | Based on the monitoring data of main ecological factors of spring and summer in Qinhuangdao coastal area from 2005 to 2011, the assessment and analysis of the water quality and eutrophicaton were made using the methods of single factor and eutrophicaton index. in addition, the relation between eutrophication and red tide was discussed. The result showed that the factors of COD and DIN maintained a stable level, the factor of DIP is the limited factor of eutrophicaton and red tide. The area had high risk of red tide changed from west to the east along Beidaihe Bath. The content of nutrition was consumed when the large red tide happened, and it appeared the low eutrophicaton index in spring and summer. |
