摘　　要：为加强对重点海域水环境质量的掌握以及保护海洋生态环境,文章基于24个站位的监测结果,综合单因子污染指数法、富营养指数法和有机污染评价指数法的评价方法,评价2015-2019年滦河口-北戴河海域水环境质量状况。研究结果表明:研究区域整体水质较好;无机氮、活性磷酸盐和化学需氧量存在不同程度的超标现象,但大部分站位符合第一类海水水质标准;2015年和2018年位于河口的站位处于富营养状态,其他年份和站位均处于贫营养状态;除近岸和河口的个别站位外,海水未受到有机污染,水质处于较好或良好状态,且有继续向好发展的趋势。In order to strengthen the mastery of the water environment quality of key sea areas and protect the marine ecological environment, based on the monitoring results of 24 stations, this paper evaluated the water environment quality of Luanhe estuary-Beidaihe sea area from 2015 to 2019 by integrating the evaluation methods of single factor pollution index method, eutrophication index method and organic pollution evaluation index method. The results showed that the overall water quality in the study area was good. Inorganic nitrogen, active phosphate and chemical oxygen demand exceed the standard in varying degrees, but most stations met the class Ⅰ seawater quality standard. In 2015 and 2018, individual stations at the estuary were in eutrophic state, and other years and stations were in oligotrophic state. Except for individual stations near the shore and estuary, the seawater was not organically polluted, the water quality was in about good or good condition, and there was a trend of continuous development.
