摘要
本文根据海南澄迈湾2017年、2018年、2019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澄迈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:澄迈湾海域在监测时段内整体水质优良,各站位测值均符合国家一、二类海水水质标准;澄迈湾在监测时段内大部分海域处于贫营养化状态,花场湾内部存在部分轻度富营养化情况;该海域各项海水监测指标呈现由湾内向湾外递减的趋势。该研究可为澄迈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(2017~2019),this paper analyses on the seawater pollution state in Chengmai Bay of Hainan,using single-factor quality index analysis method,eutrophication level evaluation method,and draws an analysis of pollution factors in the sea area using GIS.The result shows:this place was excellent in overall water quality during the monitoring period,the measured values of each station met the national class I and class II sea water quality standards;the most part of the Chengmai Bay sea area were in the state of poor nutrition in the monitoring of the period of time,there were some slight eutrophication in the inner part of Huachang Bay,and the monitoring indexes of the sea water decreased from the inner part of the bay to the outer part of the bay.The study can provide reference for the ecological environment protection and research in Chengmai bay.
