摘　　要：海洋是高质量发展的战略要地,海洋生态文明建设和海洋生态环境保护受到高度重视。本文对2020—2022年奉贤区附近海域无机氮的年际变化与分布特征进行了研究,了解奉贤沿海海域内无机氮的变化情况,探究各成分的分布情况。结果表明,奉贤海域的无机氮劣于第四类海水水质标准,硝酸盐氮是主要影响因素,其浓度在空间分布上表现为杭州湾湾内向湾外逐步降低。The ocean is a strategic place for the strategy of high-quality development,and the construction of Marine ecological civilization and the protection of Marine ecological environment have received great attention.In this paper,the interannual changes and distribution characteristics of inorganic nitrogen in the waters near Fengxian during 2020-2022 were studied to understand the changes of inorganic nitrogen in the coastal waters of Fengxian and explore the distribution of each component.Results On the surface,the inorganic nitrogen in Fengxian sea area was worse than the fourth type of seawater quality standard,and nitrate nitrogen was the main influencing factor,and its spatial distribution showed a gradual decrease from inner to outer Hangzhou Bay.
