摘　　要：为全面了解秦皇岛近岸天然重要渔业水域的水质与富营养化状况,根据2024年春、夏季秦皇岛近岸天然重要渔业水域的监测结果,采用单因子指数法、富营养指数法、重金属综合污染指数法对该海域水质进行了分析。结果表明,该海域pH值、溶解氧、化学需氧量、无机氮监测结果符合海水水质一类标准,石油类、铜、铅、锌、镉、汞、砷符合渔业水质标准,重金属污染综合指数显示调查海域重金属污染效应为没有影响,富营养化指数均小于1,处于贫营养状态。In order to comprehensively understand the evaluation of water quality and eutrophication status of key natural marine fishery waters near Qinhuangdao,the water quality of the sea area was analyzed by using the single-factor index method,the eutrophication index method,and the heavy metal comprehensive pollution index method,based on the results of the monitoring of Qinhuangdao's near-shore natural important fishery waters in the spring and summer of 2024.The results showed that pH,DO,COD and inorganic nitrogen in this sea area conformed to the first class standard of seawater quality,and the petroleum,Cu,Pb,Zn,Cd,Hg and As conformed to the fishery water quality standard,and the heavy metal pollution composite index showed that there was no influence of the heavy metal pollution effect in the investigated sea area,and the eutrophication indexes were all less than 1,which were in the state of depletion of nutrients.
