    摘要:

    根据2015年6月对威海双岛湾的海洋生态环境调查资料,分析了DIN、PO4-P和COD的特征及限制性因子,综合运用单因子指数、水体富营养化指数和有机污染状况评价等方法对该海域富营养化程度进行了评价。结果显示: NO3-N为DIN的主要存在形式,DIN为双岛湾的主要污染因子, DIN、PO4-P和COD平均浓度为164.99μg/L、4.51μg/L和0.93mg/L。除部分站位DIN外,其余站位DIN、PO4-P及COD浓度均符合一类海水水质标准。营养盐及COD浓度平面分布总体呈现南高北低,湾内高于湾外趋势。N/P均值为83.04,营养结构特征为磷限制,对比历史数据,双岛湾N/P失衡呈逐年加剧趋势。富营养化指数均值为0.16,海水有机污染指数变化区间为-0.62~1.02,与富营养化指数法相比,海水有机污染指数法结论更为客观。

    Abstract:

    According to investigations in the Shuangdao Bay,Weihai,in June2015,including DIN,PO4-P and COD, nutrients characteristics in concentration and restrictive analysis were studied, and the eutrophication degree of the Shuangdao Bay was assessed by single factor index, eutrophication index and organic pollution comprehensive index. The results showed that NO3-N was the chief form of DIN,and DIN was the principal contamination parameter for water quality of the Shuangdao Bay. The mean concentrations of DIN, PO4-P and COD were 164.99μg/L, 4.51μg/L and 0.93mg/L,respectively.Except for concentrations of DIN in some monitoring stations, the concentrations of DIN, PO4-P and COD in all the reststations attained the gradeⅠStandard of Seawater Quality.In general the horizontal distribution of nutrients and COD of Shuangdao Bay tended to be higher in the south than the north, and higher in the inside than the outside. The mean ratio of N: P of Shuangdao bay is 83.04, and the structure of nutrients is characterized by phosphorus-limitation in the Shuangdao bay. Comparing with historical data, the imbalance of N: P ratio is getting more serious year by year. The average rate of eutrophication index in Shuangdao bay is 0.16, and the organic pollution comprehensive indices of twelve investigations range from -0.62~1.02. The results of organic pollution comprehensive index are more objective than those of the eutrophication index.
