根据我国中亚热带海岛生态特征及其地理分布，文章选取八个具有代表性的典型海岛作为研究对象。采用单因子评价方法和反映营养盐限制特征的海水富营养化评价方法，对我国中亚热带的八个典型海岛的周边海域海水质量展开了评价。研究结果表明，我国中亚热带典型海岛周边海域海水质量总体良好，但是氮磷含量普遍超标，无机氮和活性磷酸盐是主要污染指标；我国中亚热带典型海岛周边海域海水基本属于磷限制并且营养级程度不同；造成海水富营化的主要原因是陆源的流域污染和沿岸污水排放以及海上的养殖污染。

In this paper, eight typical islands were selected as the research object, according to the ecological characteristics and geographical distribution of the mid-subtropical islands in China. Single-factor water quality evaluation method and eutrophication evaluation method which accounts for nutrient limitation were used to evaluate the seawater quality status of eight typical mid-subtropical islands in China. The results showed that the seawater quality of these typical mid-subtropical islands in China was generally good, other than inorganic nitrogen and active phosphate which were considered as major pollutants of seawater around these typical mid-subtropical islands; the seawater around these islands was usually phosphorus-limited and the nutritional level was different; the main reasons of seawater eutrophication were river basin pollution, coastal wastewater discharge and aquaculture pollution.
