摘要
本文根据海南陵水湾2014年2015年2016年三年水质监测结果,采用水质单因子质量指数分析方法、富营养化水平评价法对海南陵水湾水质污染状况进行分析评价,并采用GIS软件对该海域污染因子进行绘图分析。结果表明:海南陵水湾海域在监测时段内整体水质较为优良,2014~2016年无机氮、磷酸盐、溶解氧、化学需氧量测值均符合国家二类海水水质标准,2016年石油类符合国家三类水质标准;陵水湾富营养化水平统计结果显示,2014~2016年该海域富营养化指数较低,监测时段内该海域均处于贫营养状态;该海域各项海水监测指标呈现由湾内向湾外递减的趋势。该研究可为陵水湾生态环境保护和研究提供参考。
Base on the monitoring results of water quality in the past three years （2014-2016）, this paper analyses on the seawater pollution state in Lingshui Bay of Hainan, using single-factor quality index analysis method, comprehensive evaluation method, eutrophication level evaluation method, and draws an analysis of pollution factors in the sea area using GIS to do drawing analysis. The result shows： this place is excellent in overall water quality during the monitoring period, inorganic nitrogen, phosphate, dissolved oxygen, chemical oxygen demand are in line with the national second class of sea water quality standards. Oil is in line with the three types of water quality standards in 2016. The eutrophication index in this sea area is lower in 2014-2016 years. The stations in the waters are in the monitoring of the period of time are in the state of poor nutrition. The seawater monitoring indicators in the waters are decreasing from the Gulf to the Bay. This study can provide reference for Lingshui Bay ecological environment protection and research.
