摘　　要：城市河流的水质常受暴雨引起的波动影响,洪水的不确定性会导致水质变化。2023年7月28日-8月5日,在北京市北运河上游温榆河尹各庄枢纽利用自动监测站采集水样,分析了氨氮、总磷、化学需氧量、总氮、电导率、浊度6个水质参数。结果发现,氨氮、总磷、化学需氧量、电导率和浊度水质指标与河道流量和径流的变化密切相关。研究成果为暴雨洪水形成的极端事件下,城市河流水资源管理提供了一定的借鉴和参考。Urban fluvial systems exhibit pronounced water quality volatility under hydrological perturbations induced by extreme precipitation events,and the unpredictability of floods can lead to changes in water quality.Water samples were collected from July 28 to August 5,2023,at the automatic monitoring station located at the Yingezhuang hub of the Wenyu River in the upper reaches of the North Canal in Beijing.Six water quality parameters-ammonia nitrogen,total phosphorus,chemical oxygen demand(COD),total nitrogen,conductivity,and turbidity-were analyzed.lt was found that the water quality indices for ammonia nitrogen,total phosphorus,COD,conductivity,and turbidity are closely related to changes in river fow and runoff.These research findings provide valuable references for managing urban river water resources during extreme events caused by rainstorms and floods.
