摘　　要：海洋环境质量评价是海洋环境污染防治的前提,是改善海洋环境质量急需解决的问题。应用灰色关联法和单因子评价法,基于2017年监测数据,对厦门海域水质进行综合评价。评价结果显示:西部海域、同安湾和九龙江河口的水质状况差,南部海域、东部海域和大嶝海域的水质状况优良,2017年厦门海域水质状况总体差。两种评价方法中,单因子评价法会使得评价结果总体上差一个水质类别,不能体现各评价因子对海洋环境质量的影响,从而无法全面地反映海洋环境污染的客观情况,而灰色关联法能够综合地反映各评价因子对海洋环境质量的污染状况。Marine environmental quality evaluation is the prerequisite for the prevention and control of marine environmental pollution,and it is an urgent problem to be solved to improve the quality of the marine environment.By using the grey correlation analysis and single factor evaluation methods,based on the monitoring data in 2017,the comprehensive evaluation of Xiamen sea water quality is carried out.The results show that the water quality in the western sea area,Tong'an Bay and the Jiulongjiang estuary was poor.The water quality in the southern,eastern and Dadeng sea area is in good condition.Overall,the water quality in Xiamen sea area in 2017 was poor.Of the two evaluation methods,the single factor evaluation method will make the evaluation results generally worse by one water quality level,and cannot reflect the impact of each evaluation factor on marine environmental quality,thus failing to reflect the situation of marine environmental pollution,while the grey correlation analysis can comprehensively reflect the pollution of each evaluation factor on marine environmental quality.
