摘　　要：为有效研究徒骇河济南段地表水水质状况及变化趋势,为徒骇河污染治理、河流健康、生态发展提供理论依据,利用污染指数法和Daniel趋势检验法,选取2001~2020年徒骇河济南段2个监测断面连续20年的地表水监测数据进行了水质评价及变化趋势分析。结果表明:近20年,徒骇河济南段超标项目有高锰酸盐指数、化学需氧量、生化需氧量、氨氮、总磷、挥发酚等,综合污染指数下降明显,各断面水环境质量呈改善趋势,污染状况大大减轻。夏口、申桥断面大部分监测指标的污染指数呈下降趋势,化学需氧量、高锰酸盐指数、生化需氧量、石油类好转趋势最为明显。济南市积极推进徒骇河水环境的治理与改善工作,外源性污染物输入持续降低是徒骇河济南段水质改善的主要原因,其次为上游来水的水质改善。In order to study the surface water quality status and change trend of Tuhai River in Jinan,and provide a theoretical basis for Tuhai River pollution control,river health and ecological development.Using the pollution index method and Daniel trend test method,the surface water monitoring data of two monitoring sections in Jinan section of Tuhai River from 2001 to 2020 for 20 consecutive years are selected for water quality evaluation and change trend analysis.The results showed that in recent 20 years,the indexes exceeding the standard in Jinan section of Tuhai River include permanganate index,chemical oxygen demand,biochemical oxygen demand,ammonia nitrogen,total phosphorus and volatile phenol.The comprehensive pollution index decreased significantly,the water environmental quality of each section showed an improvement trend,and the pollution situation was greatly reduced.The pollution index of most monitoring indexes in Xiakou and Shenqiao sections showed a downward trend,and the improvement trend of chemical oxygen demand,permanganate index,biochemical oxygen demand and petroleum was the most obvious.Jinan actively promotes the treatment and improvement of Tuhai River environment.The continuous reduction of exogenous pollutant input is the main reason for the improvement of water quality in Jinan section of Tuhai River,followed by the improvement of water quality in the upstream.
