摘 要: | 2015年10月,对海南三亚珊瑚礁国家级自然保护区进行水质调查,调查站点布设三亚西瑁洲西端3个站点,鹿回头南端4个站点,亚龙湾2个站点,共布设9个调查站点。分析了水温、p H、盐度、溶解氧、化学需氧量、活性磷酸盐、无机氮、油类、铜、铅、锌、镉、汞、砷共14项指标。采用单项水质指数法、有机体污染指数法以及水质富营养化指数法对三亚珊瑚礁国家级自然保护区附近海域水质进行分析和评价,结果显示:该海域水质评价指数均小于1,单因子指数较小;有机污染评价指数A1,污染物浓度较低;富营养化评价指数E1,该海域海水水质均符合第一类海水水质标准,水质处于良好状态。

Evaluation of Sea Water Quality Environmental conditions in Sanya Coral Reef National Nature Reserve |

Abstract: | In order to investigate the sea water quality in Sanya Coral Reef National Nature Reserve, Hainan 9 sites were set in October 2015: 3 sites at the west of Ximaozhou Island, 4 sites at the south of Luhuitou and 2 sites at Yalong Bay. A total of 14 parameters were analyzed for sea water quality evaluation, including temperature, pH, salinity, dissolved oxygen, chemical oxygen demand, active phosphate, inorganic nitrogen, oils, copper, lead, zinc, cadmium, mercury, arsenic. single water quality index (SWQI), organic pollution index (OPI) and eutrophication index (EI). The results showed that the SWQI, OPI and EI were all less than 1, and that the sea water quality conformed to the first class sea water quality standard, indicating the water quality was good. |
