根据2011年对秦皇岛近岸海域水质调查结果,应用单因子法、有机污染指数法和富营养化指数法对该海域海水的质量状况进行了评价与分析。结果表明,pH、DO、COD、PO43--P和DIN均存在不同程度的超标,其中pH、COD和PO43--P超标严重;调查海域春季海水状况好于夏季和秋季,由春季到秋季,调查海域受到有机污染的范围逐渐扩大,贫营养水平海水范围逐渐缩小,中营养和高营养水平海水范围逐渐扩大。
根據2011年對秦皇島近岸海域水質調查結果,應用單因子法、有機汙染指數法和富營養化指數法對該海域海水的質量狀況進行瞭評價與分析。結果錶明,pH、DO、COD、PO43--P和DIN均存在不同程度的超標,其中pH、COD和PO43--P超標嚴重;調查海域春季海水狀況好于夏季和鞦季,由春季到鞦季,調查海域受到有機汙染的範圍逐漸擴大,貧營養水平海水範圍逐漸縮小,中營養和高營養水平海水範圍逐漸擴大。
근거2011년대진황도근안해역수질조사결과,응용단인자법、유궤오염지수법화부영양화지수법대해해역해수적질량상황진행료평개여분석。결과표명,pH、DO、COD、PO43--P화DIN균존재불동정도적초표,기중pH、COD화PO43--P초표엄중;조사해역춘계해수상황호우하계화추계,유춘계도추계,조사해역수도유궤오염적범위축점확대,빈영양수평해수범위축점축소,중영양화고영양수평해수범위축점확대。
Based on the monitoring results of water quality in Qinhuangdao Inshore in 2011 ,single fac-tor method ,index of organic pollution method and eutrophication level method were used to analyze and evaluate the water quality of coastal water .The results show that :the concentrations of pH、DO、COD、PO4 3 - -P and DIN exceed the standard to varying degrees ,the degrees of pollution of pH 、COD and PO43 - -P were aggravated ;the water quality in spring is better than that in summer and autumn , from summer to autumn ,the scope of the organic pollution is gradually expanding ,the scope of oligo-trophic water is gradually narrowing ,the scope of middle eutrophication and high eutrophication are gradually expanding .
