摘　　要：为摸清海河干流天津市区段渔业生态环境质量状况,2016—2021年对该水域pH、高锰酸盐指数、总氮、总磷、石油类、溶解氧、铜、锌、砷进行了连续监测。调查结果表明,7月份总氮、总磷、高锰酸盐指数等指标劣于5月份和9月份。总体来说,2016—2021年总氮、总磷、高锰酸盐指数、铜、锌、砷等指标下降明显,渔业生态环境得到一定程度的改善。To understand the ecological environment quality in Tianjin urban section of the main stream of the Haihe River,pH value,permanganate index,total nitrogen,total phosphorus,petroleum,dissolved oxygen,copper,zinc,and arsenic in the water area were continuously monitored from 2016 to 2021.The survey results showed that indicators such as total nitrogen,total phosphorus,and permanganate index in July were inferior to those in May and September.Overall,from 2016 to 2021,the total nitrogen,total phosphorus,permanganate index,copper,zinc,arsenic and other indicators decreased significantly,and the fishery ecological environment was improved to a certain extent.
