摘要
目的:研究涠洲岛水质现状及变化趋势。方法:2021年4月在涠洲岛附近海域进行水质环境质量调查及评价。根据2007年至2021年涠洲岛海域水质调查资料研究水质变化趋势。结果:pH、溶解氧、化学需氧量未超一类海水标准。部分站位无机氮、无机磷超一类海水标准,且有逐年增长的趋势。结论:该海域并未达到富营养化,溶解氧、化学需氧量有较大的环境容量。基于涠洲岛海水强大的物理、化学、生物自净能力及适宜的营养盐结构,较高浓度的营养盐并未引起水质恶化。
Objective:This paper studies the present situation and change trend of water quality in Weizhou Island.Methods:In April 2021,the water quality and environmental quality of the sea area near Weizhou Island were investigated and evaluated.Based on the water quality survey data of Weizhou Island from 2007 to 2021,the change trend of water quality is studied.Results:pH,dissolved oxygen and chemical oxygen demand did not exceed class I seawater standard.The inorganic nitrogen and phosphorus of some stations exceed the first class seawater standard,and the trend is increasing year by year.Conclusion:The sea area is not eutrophication,dissolved oxygen and chemical oxygen demand have large environmental capacity.Based on the strong physical,chemical and biological self purification ability of Weizhou Island seawater,high concentration of nutrients did not cause water quality deterioration.
