中文摘要:
      利用2017年度河北省近岸海域相关监测数据,采用单一因子法对近岸海域环境质量进行了评价与分析。结果表明:2017年河北省近岸海域环境质量点位以二类水质类别为主,整体水质状况为一般。一类水质比例为0%;二类水质比例为76.9%;四类及劣四类水质比例为23.1%。近岸海域水质状况为一般,超标因子为无机氮,入海河流及直排入海污染源携带污染物对近岸海域水质影响明显,因此河北省近岸海域污染控制重点应在无机氮污染。
英文摘要:
      Using the water quality data of samples in the coastal waters of Hebei Province in 2017, a single factor method was used to evaluate environmental quality. The results showed that the environmental quality sites in the coastal waters of Hebei Province are mainly in water Grade Two, and the overall water quality status is general in 2017. The proportion of water quality in Grade Ong and Two is 0% and 76.9%,respectively, while the proportion of water Grade Four and inferior grade is 23.1%. The coastal waters of Hebei Province is general, and the excess factor is inorganic nitrogen. The coastal waters quality was affected by the pollutants carried by the sea rivers and discharged directly into the source of pollution. Pollution control in the coastal waters of Hebei province should focus on inorganic nitrogen pollution.
