摘　　要：为全面系统掌握刘公岛周边海域海水质量状况,为水环境管理和科学合理用海提供数据支撑,本文根据刘公岛周边海域20站位监测数据,采用单因子污染指数法、有机污染指数法、营养化指数法和综合污染指数法进行了海水质量评价。结果表明:刘公岛周边海域的pH、溶解氧(DO)、化学需氧量(COD)、无机氮、活性磷酸盐的单因子污染指数均小于1,均符合海水一类水质标准;有机污染指数A的范围为-0.48~0.08,平均值为-0.26,整体水质状况良好;营养化指数E的范围为0.02~0.10,平均值为0.04,均为贫营养化;表层重金属综合污染指数WQI的范围为0.29~0.50,平均值为0.43,整体属于清洁水平。In order to comprehensively and systematically learn present conditon of the seawater quality in the surrounding waters of Liugong Island,and provide data support for water environment management and scientific and rational use of the sea,by using single factor pollution index method,organic pollution index method,eutrophication index method,and comprehensive pollution index method,seawater quality has been evaluated based on monitoring data from 20 stations in the surrounding waters of Liugong Island.It is showed that the single factor pollution indices of pH,dissolved oxygen(DO),chemical oxygen demand(COD),inorganic nitrogen,and active phosphate in the surrounding waters of Liugong Island are all less than 1.It can meet the first-class seawater quality standards.The range of organic pollution index A is -0.48~0.08,the average value is -0.26.The overall water quality is good.The range of nutritional index E is 0.02~0.10,the average value is 0.04,and all are malnutrition.The comprehensive pollution index(WQI)of surface heavy metals ranges from 0.29 to 0.50,the average value is 0.43,and is in an overall clean level.
