摘　　要：以连云港市近岸海域水质监测近年数据为基础,依照海水水质评价标准对该海域水质的站点达标率进行统计分析,采用有机污染物指数法和富营养化指数法,对调查区域海水有机污染、营养水平等进行综合评价。结果表明,2018年研究海域站点全年达标率为68.9%,达标面积达到5488 km2,占管辖海域面积的82.2%,春季、秋季的水质状况整体要好于夏季;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处于较好的状况,但其富营养化程度总体水平较高,近岸水质要劣于远岸水质,且随季节的更替呈现波动性变化。Based on the data of the coastal water quality monitoring of Lianyungang City in recent years,the station compliance rate of the water quality of the sea area was statistically analyzed in accordance with the sea water quality evaluation standards.The organic pollutant index method and eutrophication index method were adopted to comprehensively evaluate the organic pollution and nutrient level of the seawater in the investigated area.The results show that the annual reaching-standard rate of the survey sites is 68.9 percent in 2018,the standard area reaches 5488 km2,accounting for 82.2 percent of the sea area under its jurisdiction.Water quality in Spring and Autumn is superior than it in Summer.The main superscalar includes inorganic nitrogen and activated phosphates and the study sea area is free from organic contamination.However,the water quality is at higher-eutrophication level.The water quality of offshore areas is inferior to it far from the sea.Furthermore,water quality shows the fluctuation change with the replacement of seasons.
