摘　　要：围绕汛期河道水环境质量波动问题,选取南方长江下游典型河道某考核断面为典型研究单元,对土壤氮磷污染情况展开调查研究。并在此基础上构建研究区域典型河段的水动力和水质耦合模型,结合同步监测数据进行参数率定及验证,分析TP、TN的污染特征并核算其对河道氮磷污染的贡献率,旨在为污染管控及河道科学治理提供理论支持。Focusing on the fluctuation of river water environment quality during the flood season,a typical section of a typical river in the lower reaches of the Yangtze River in the south was selected as a typical research unit to investigate the soil nitrogen and phosphorus pollution.On this basis,a coupling model of hydrodynamic and water quality was constructed for typical river reach in the study area,and parameter calibration and verification were carried out combined with synchronous monitoring data.Pollution characteristics of total phosphorus and total nitrogen were analyzed and its contribution rate to river nitrogen and phosphorus pollution was calculated,providing theoretical guidance for pollution control and scientific river management.
