摘　　要：由于近岸海域水环境质量是滨海区域可持续发展的重要基础,针对河北黄骅近岸海域,系统分析了2006~2017年无机氮污染物的年均值变化情况,探讨了海域环境质量演变规律;并以不同时期实测资料,研究了黄骅港区工程建设与环境质量间的相互关系。结果表明:黄骅海域无机氮污染物年均值大多超过海水水质二类标准,部分年份超四类海水水质标准;无机氮污染物含量变化与海洋工程建设的相关性不明显,其可为区域经济发展和海洋环境保护提供参考。The quality of sea water environment is important prerequisite for regional sustainable development of nearshore districts.In this paper,annual mean value of DIN from 2006 to 2017 is analyzed to discuss the evolution rules of marine environment quality.The relationship of environmental quality with Huanghua port construction is analyzed by the different periods.The research results show that the annual average of inorganic nitrogen pollutants in Huanghua sea area is mostly higher than the second-class standard of seawater quality.In some years,it exceeds the fourth-class seawater quality standard;the correlation between the content of inorganic nitrogen pollutants and marine engineering construction is not obvious,which provides basic support for regional economic development and marine environment protection.
