| 摘要: |
| 于2019年春、夏、秋季对连云港近岸海域海水中营养盐、重金属等共19项指标进行3个航次采样监测。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年连云港市海域站位全年达标率为86.4%，达标面积为6543 km2，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。调查海域海水的有机污染和富营养化程度均处于良好状况，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, the writer had samply monitored 19 indicators including nutrients and heavy metals of offshore area in the spring, summer, and fall in 2019.Furthermore,the writer applied Organic pollutant index method and eutrophication index method ,which were made according to the reaching standard rate of seawater quality evaluation standard,to comprehensively evaluate the Organic pollution of sea waters and nutrient level.The results show that the annual reaching standard rate of the survey sites is 86.4 percent in 2019, the reaching standard area reaches 6 543 km2,which accounts for 98 percent of the sea area under jurisdiction.The quality of water was further improved than previous years.The main superscalar includes inorganic nitrogen and phosphates. The comprehensive evaluation results show that the organic pollution and eutrophication of survey seawater are in good condition.The water quality of offshore areas is inferior to that far from the sea.Furthermore, water quality shows the fluctuation change with the replacement of seasons. |
