摘　　要：针对中小城市供水管网分区对供水的管理,提出了供水管网三层分区(调度分区、压力分区、DMA分区)方法,形成了"自中间向两边"的供水管网多级分区综合体系。以南方CP市供水管网为例,首先对城市供水管网的管段进行聚类分析确定二级分区,并优化减压阀设置降低漏失率;然后在二级分区的基础上,合理规划水源供水,优化泵组调度系统,实现一级分区;最后细化二级分区形成流量计量的三级分区,实现漏失定位。Based on the significance of small and medium-sized city water supply network partition for water supply management, three-level partition of water supply network, including scheduling partition, pressure partition and DMA partition was put forward to form the water supply network multistage partition comprehensive system of ＂from middle to both sides＂. With the CP city water supply network as example, the urban water supply network was clustered to determine the secondary partition, and leakage rate was reduced by optimizing the setting of relief valves. Based on the secondary partition, the water supply was rationally planned and pumps scheduling system was optimized to realize the primary partition. Meanwhile, the third partition was formed by refining the secondary partition to find the leakage location.
