摘　　要：2012—2013年,根据夏秋冬三个季度3个航次海水水质的监测结果,对福建南日岛东岱村北部海域夏秋冬海水水质营养状况进行分析与评价。结果表明,南日岛东部东岱村北部海域海水水质良好,无机氮、化学需氧量及石油类符合国家一类海水水质标准,无机磷则在2013年2月航次监测中达到三类海水水质标准,海区富磷现象明显。总体而言,该海域海水处于健康状态,能够满足野生坛紫菜生长要求。According to the survey of seawater quality and nutritional status at sea area around Dong Dai vil-lage in Nan Ri island in June, October 2012 and in March 2013, the result suggested that the quality of sea-water in this area is good, inorganic nitrogen, chemical oxygen demand and oil are in accordance with Chinese national 1st class water quality standards. On the contrary, the inorganic phosphorus reached the 3rd class of Chinese national water quality standards in February voyage in 2013 . The phosphorus-rich phenomenon is obvious. By the value of E, TSIM and WQI, the seawater in February voyage in 2013 shows a light pollution, to whick the key factor leading is inorganic phosphorus. It could be ascribed to the abalone nursery industry. Overall, seawater in this area is in a healthy state, and can meet the wild P. haitanensis growth requirements, but we should be attention to the phosphorus-rich phenomenon, otherwise which will lead to environmental degradation.
