摘　　要：根据芝罘湾2014—2020年的水质监测结果,分析了海水中的溶解氧、化学耗氧量、无机氮和活性磷酸盐的含量逐年变化情况。依据国家海水水质标准,使用模糊综合评价法具体分析了各年份芝罘湾水质情况。评价结果表明,溶解氧和化学耗氧量年波动较大,无机氮和活性磷酸盐含量逐年下降。2016年以前,芝罘湾的水质改善情况较差,2014年的水质为Ⅳ类水,2018—2020年期间保持为Ⅰ类水,主要污染物为无机氮。整体水质等级逐年上升,表明水质在逐渐变好。Based on the water quality monitoring results of zhifu Bay from 2014 to 2020,the changes in dissolved oxygen,chemical oxygen consumption,inorganic nitrogen,and active phosphate content in seawater were analyzed year by year.And based on the national seawater quality standards,the fuzzy comprehensive e-valuation method was used to analyze the water quality situation of zZhifu Bay in various years.The water qual-ity evaluation results indicate that the annual fluctuations in dissolved oxygen and chemical oxygen consump-tion are significant,while the content of inorganic nitrogen and active phosphate decreases year by year,Prior to 2016,the water quality improvement in Zhifu Bay was poor.In 2014,the water quality was classified as Class IV water,while it remained classified as Class I water from 2018 to 2020,with inorganic nitrogen as the main pollutant.The overall water quality level has been increasing year by year,indicating that the water qual-ityisgradually improving.
