摘　　要：2017年10月对广东徐闻珊瑚礁国家级自然保护区内水质进行调查监测,共设置调查站位10个。监测指标包含pH值、水温、盐度、透明度、溶解氧、亚硝酸盐、氨氮、硝酸盐、活性磷酸盐、 COD、石油类、悬浮物等12个。采用单项水质指数法、有机体污染指数法以及水体富营养化指数法对监测海域水质进行分析与评价。结果显示:广东徐闻珊瑚礁国家级保护区内部分站位活性磷酸盐含量超标,导致对应站点水质评价指数>1,有机污染指数>1,但富营养化评价指标在10个站位均<1,表明保护区内水质开始受到轻微污染。Ten sites were set in October 2017 to monitor water quality in Xuwen Coral Reef National Natural Reserve in Guangdong Province,China,and 12 parameters in the water,including pH,temperature,salinity,dissolved oxygen,nitrite,ammonia nitrogen,nitrate,active phosphate,COD,petroleum,suspended solids,were monitored.Single water quality index (SWIQ),organic pollution index (OPI) and eutrophication index (EI) were used to analyze and assess the water quality.The results showed that the content of active phosphate in some monitoring sites exceeded the standard so that the water quality evaluation index was>1 and organic pollution index>1 in these sites.However,the eutrophication index was<1 in all the 10 monitoring sites,indicating that the water quality in this National Natural Reserve started to suffer slight contamination.
