摘　　要：系统地总结了供水管网状态估计的研究内容,包括参数估计、校核评估、数据(样本)设计。20年来国内外学者根据优化和统计分析理论并结合现场试验,提出了系统的理论分析和数值方法,近年来管网不确定分析理论被引入到管网校核评估和管网率定的样本数据设计中。此外还介绍了国外供水管网状态估计的精度标准。指出虽然相关理论研究有了较大进展,但应用研究相当薄弱,大型管网模型成功率定的实例还鲜有报道,今后应加强实用研究。The state estimation of water distribution system is systematically summarized, which includes parameter estimation, calibration assessment and data （sample） design. In the past twenty years, many researchers proposed some theory analysis and numerical technologies based on optimization, statistic theory and field experiments. In recent years, uncertainty theory is applied in the calibration assessment of water distribution network and the sample design. The accuracy standard for state estimation of water distribution network in foreign countries is introduced. Although the theory about the state estimation of water distribution network has made a great progress, there is lack of the application researches, and few examples of large scale water distribution system calibration are reported. The focus of state estimation is the application research in the future.
