摘　　要：为促进流域运维数字化与智慧化发展,更好地服务智慧水利应用决策板块,以水量平衡及物质守恒原理为基础,依托基于水质、水量监测设备的流域智慧感知体系,快速获取全要素监测数据。围绕污染源占比和超标贡献率指标,研究流域控制断面污染负荷分析方法,并以广东省M河流域2022年5月降雨期间控制断面返劣为例,对M河下游出口断面水量平衡和污染物浓度进行计算。结果表明:降雨期间,S市支流1、支流20、支流23、初雨箱涵溢流及D市各支流为控制断面主要氨氮来源,并通过超标贡献率计算结果判断支流22及支流24在后续考核断面达标治理中应予以更高优先级。研究方法相比传统模型计算和溯源排查具有原理简单、使用便捷、精度可控等优势,可有效支撑智慧应用与决策。In order to promote the digital and intelligent development of watershed operation and maintenance,and better serve the decision-making plate of intelligent water conservancy application,the system is based on the principle of water balance and conservation of matter,and relies on the watershed intelligent perception system based on water quality and water quantity monitoring equipment to quickly obtain the total factor monitoring data.Arounding the indicators of pollution source proportion and exceedance contribution rates,the analysis method of pollution load for basin control section is studied.Taking the example of the control section deterioration during the May 2022 rainfall period in the M river basin in Guangdong Province,where the construction of the intelligent perception system was relatively complete,the calculation and analysis were carried out.The results indicated that during the rainfall,tributaries 1,20,and 23 of city S,the overflow of initial rain culvert overflow,and tributaries of city D were the main sources of ammonia nitrogen for the control section.Through the calculation results of the exceedance contribution rate,it was identified that tributaries 22 and 24 had a higher priority in subsequent standard achieving treatment assessment.In comparison with traditional model calculations and source traceability methods,this method can be simple,convenient,and controllable accuracy,and can effectively support the intelligent application and decision-making.
