【摘要】 根据2015年10月份开展的水质监测结果,采用综合污染指数、有机污染指数和富营养化指数对秦皇岛主要入海河口的水质状况进行分析评价。结果显示:秦皇岛市入海河口的首要污染物为DIN、DIP;大蒲河口、汤河口和新开河口的有机污染较为严重;大蒲河口、汤河口和洋河口处于重度富营养状态,其次为戴河口、新开河口和石河口。建议对入海污染物进行严格的总量控制,加强对港口、船舶的环境污染监管,从而进一步改善近岸海域的生态环境。更多还原

【Abstract】 According to the monitoring result of water quality in 2015 October,the water quality status of the main estuaries in Qinhuangdao was analyzed with comprehensive pollution index,organic pollution index and eutrophication level index.The results showed that the key pollutants of the main estuaries were DIN and DIP;the organic pollution was more serious at the estuaries of Dapu River,Tanghe River and Xinkai River;the estuaries of Dapu River,Tanghe River and Yanghe River were extreme eutrophication,followed by the estuaries of Daihe River,Xinkai River and Shihe River.It is suggest that the total amount control for the pollutants into the sea should be strictly carried out,the supervision for the pollution caused by the ports and ships should be strengthened to improve the ecological environment of the inshore.更多还原
