摘 要:根据2017年4月对黄骅市近岸海域的调查结果,分析该海域营养盐基本特征。结果显示,DO、COD全部符合一类标准,表明该海域水体中DO充足,不易出现缺氧现象,COD含量值比较低,表明该海域调查期间有机物含量较低,无机氮所有站位均超四类标准,该海域受到无机氮污染十分严重。采用有机污染指数和海水营养化指数评价相结合的方法评价了水环境质量状况,表明该海域水质开始受到污染,调查海域为富营养状态。Based on the results of the survey on the coastal waters of Huanghua in April 2017,the basic characteristics of the nutrients in the sea area were analyzed.The results showed that DO and COD are in conformity with the standards for A class,which indicates that in this area,DO in water is sufficient,hypoxia phenomenon is not easy to appear.The value of the COD content is relatively low which showed low organic content in the water.Inorganic nitrogen in all stations were over standard IV,which indicates the area is seriously affected by inorganic nitrogen pollution.The organic pollution index and seawater nutrition index evaluation method were used to evaluate the water environment quality.The results showed that the water quality of the sea area was polluted and the investigation area was eutrophic.
