摘　　要：神定河口断面属于水质考核国控断面,2019年以前,水质一直处于Ⅴ类或劣Ⅴ类,未能达到国家考核标准。通过对神定河口断面2017—2019年水质状况评价及污染源分析,剖析了神定河水质持续不达标的原因。结果表明,2017—2019年神定河水质有好转趋势。水质持续超标的原因主要是生态补水不足、污水处理能力不足、污水管网破损等,后期应加强污水处理力度及管网建设。研究成果可为神定河水质提升提供技术支撑。The Shending River estuary section is a state-controlled site for water quality assessmen.It has consistently failed to meet national standards and has been classified as Class V or worse before 2019.We investigated into the causes of such failure by evaluating the water quality and analyzing the pollution sources of the Shending River estuary section from 2017 to 2019.Results indicate that the water quality of the Shending River showed an improving trend from 2017 to 2019.The main reasons for the continuous standard-exceeding water quality indicators were identified as insufficient ecological water supplement,inadequate sewage treatment capacity,and damaged sewage pipe networks.To improve the water quality,future efforts should focus on strengthening sewage treatment and pipe network construction.These findings can provide technical support to enhance the water quality of the Shending River.
