According to the environmental monitoring for sea water in West-Maozhou Island in Hainan in June 2015, the sea water quality was evaluated by using the single index method, organic pollution index method and eutrophication index method. The results showed that single water quality parameters at the monitoring station ranged between 0.11 and 0.99, that the organism evaluation factors were less than zero, and that the E value of the eutrophication of sea water quality ranged from 0.006 to 0.027. All these showed that the sea water quality in the West-Maozhou Island was good. The content of inorganic nitrogen, oil and zinc in the sea water increased slightly in this survey as compared with those in 2010, but still conformed with the first class sea water quality standard, and other parameters were basically the same as those in 2010. This indicates that the sea water quality in the West-Maozhou Island has been good since 2010.%根据2015年6月对西瑁洲岛海域环境监测的结果,用单项水质参数法、水体有机污染指数法和富营养化指数法对西瑁洲岛海域水质环境质量进行评价。评价结果表明：所监测站位中单项水质参数所变化范围为0.11～0.99,有机体评价因子均小于0,海域水质富营养化E测定值变化范围为0.006～0.027,说明西瑁洲岛海域水质良好。本次调查结果与2010年进行比较,无机氮、油类和锌的含量略有增加,但仍符合第一类海水水质标准,其他测项基本保持在同一水平。表明自2010年以来,西瑁洲岛海域的水质环境质量一直保持良好。
