摘要:
为了解连云港近岸海域水质现状,本文于2019年春季、夏季、秋季对连云港近岸海域海水中各指标进行采样监测,应用分光光度法和ICP-MS等技术分析各指标。依照海水水质评价标准统计分析站点达标率,采用有机污染物指数法和富营养化指数法,对调查海域海水有机污染、营养水平等进行综合评价。结果表明:2019年研究海域站点全年达标率为86.4%,达标面积达到6543km2,占管辖海域面积的98.0%,水质质量较往年有所好转,主要超标物为无机氮、活性磷酸盐。综合评价结果表明调查海域海水的有机污染和富营养化程度均处于良好的状况,近岸海水水质总体上要劣于远岸水质,且随季节的更替呈现波动性变化。

Abstract:
In order to understand the water quality status of lianyungang coastal waters, Indicators in seawater were monitored in the spring, summer, and fall of 2019 in this article, Indicators were analyzed by spectrophotometry and ICP-MS.The station compliance rate was statistically analyzed according to the seawater quality evaluation standard,The organic pollution and nutrient levels of seawater were comprehensively evaluated by Organic pollutant index method and eutrophication index method. The results show that the annual compliance rate of the survey sites was 86.4 in 2019, the standard area reaches 6543km2, accounting for 98.0 of the sea area under its jurisdiction, The quality of water quality was further improved than previous years. The main superscalar includes inorganic nitrogen and phosphates.The evaluation results show that the organic pollution and eutrophication of seawater were in good condition in survey waters,The water?quality of the?offshore?Marine areas?tended?to?deteriorate,Water quality showed the law of fluctuation with the season.
