摘　　要：为了提高城市供水安全性和服务可靠性,常采用多水厂向管网供水。多水厂供水区域可分为完全由单一水厂供水区和多水厂联合供水区。这些供水区的划分,以及管网中各节点(管段)由各水厂供水百分比,可利用给水管网水质模型中的水量溯源功能分析。在叙述水量溯源原理与分析过程后,以单工况示例和延时模拟示例进行了说明。水量溯源对了解各水厂向管网供水状况具有重要意义。In order to improve the security and service reliability of urban water supply,multiple waterworks are often used to supply water to the distribution system.The water supply area with multiple waterworks can be divided into the subareas completely supplied by a single waterworks and the subareas jointly supplied by multiple waterworks.The division of these water supply subareas,as well as the percentage of water supplied by each waterworks at each node and each link in the distribution system,can be analyzed by using the source tracing function in the water quality model of the water distribution systems.After describing the principle and analysis process of water source tracing,it is illustrated by a single working condition example and an extend time simulation example.Source tracing is of great significance to understand the water supply status of each waterworks to the distribution systems.
