| 摘 要： | 文章根据岙山监测浮标周边海域2015年9-12月水质调查资料,采用水质有机污染指数(A)、富营养化指数(E)和营养状态质量指数(NQI)等进行评价。结果表明:岙山监测浮标周边海域水质化学需氧量(COD)、溶解氧(DO)、油类(oils)符合二类海水水质标准,无机磷(DIP)和无机氮(DIN)含量均超过二类海水水质标准,DIP最高为0.048mg/L,DIN最高为0.753mg/L,总磷(TP)各月平均含量范围0.098~0.185mg/L,总氮(TN)各月平均含量范围0.650~0.818mg/L,叶绿素a(Chl a)含量基本稳定,DIN是主要的超标污染因子;富营养化评价结果显示,岙山监测浮标周边海域水质富营养程度严重,E值最高达9.10,NQI值最高为4.58;有机污染评价结果表明,岙山监测浮标周边海域水质总体处于轻度污染状态,A值最小为10月的1.90,最大为12月的2.73;使用A值、E值和NQI值方法同时对岙山监测浮标周边海域进行评价,其结果变化的一致性较好。

| Abstract: | Organic pollution index of water quality were employed in this paper:(A),Eutrophication index(E) and Nutrient status quality index (NQI) to evaluate water quality around coastal waters of Aoshan buoy according to in situ monitoring data during September to December of 2015.The results indicated that chemical oxygen demand(COD),dissolved oxygen(DO) and oils of coastal waters around Aoshan buoy qualified the second class of sea water quality standard while dissolved inorganic phosphorus(DIP) and dissolved inorganic nitrogen (DIN) exceeded the second class of sea water quality standard with a highest DIP of 0.048 mg/L and a highest DIN of 0.753 mg/L.Besides,the variation range of monthly average total phosphorus (TP) and monthly average total nitrogen(TN) was 0.098~0.185 mg/L and 0.650~0.818 mg/L,respectively,and the content of Chl-a basically remains stable.DIN was the main pollutant factor in this area.According to eutrophication evaluation,eutrophication level and pollution degree were severe in coastal waters around Aoshan buoy with a highest E of 9.10 and a highest NQI of 4.58.According to Organic pollution assessment,the coastal water around Aoshan buoy was slightly polluted with a lowest A of 1.90 in October and a highest A of 2.73 in Decembe.The results of using A,E and NQI to evaluate coastal water around Aoshan buoy were consistent. |
