研究了给水管网水质监测点优化选址问题，分析了覆盖水量法存在的缺陷，提出了一种基于覆盖权重水量的优化选址方法，即在覆盖水量选址模型中引入节点水质权重。覆盖权重水量法同时考虑了节点水量与水质在空间上的分布，以及周围管道属性对节点代表性的影响，提高了监测点选址的代表性。将覆盖权重水量法应用于重庆市某区给水管网进行水质监测点优化选址，并与覆盖水量法进行对比。结果表明，在同一监测点水平，覆盖权重水量法求得的监测点选址更具有代表性和实用性，可为同类城市给水管网水质监测点选址提供参考。

The optimal location of water quality monitoring points in water supply network was explored, and defects of the demand coverage were analyzed. An optimized location method based on the coverage weight water quantity was proposed, which was to introduce the node water quality weight into the demand coverage location model. The weight demand coverage method considerd the spatial distribution of water quantity and quality of the nodes, and the influence of the surrounding pipeline properties on the node representativeness, which improved the representativeness of location of the monitoring points. The weight demand coverage method was applied to a water supply network in a district of Chongqing to optimize the location of water quality monitoring points, and the results were compared with the demand coverage method. At the same monitoring level, the monitoring points chosen by weight demand coverage method had better representativeness and practicability, which could provide reference for the location of water quality monitoring points of similar municipal water supply network.
