南水北调中线工程水量调度实践及分析

南水北调中线一期工程全面通水两年来, 工程安全平稳运行, 输水水质全线达标, 累计从渠首陶岔引水超过 60 亿 m3。为更好地优化中线工程的实时供水调度, 有必要对中线工程的水量调度方案、水量调度计划和近两年的水量调度实践进行系统的总结。介绍了南水北调中线水量调度方案、丹江口水库年度可调水量、中线工程年度水量调度计划以及中线工程近两年水量调度实践, 分析了中线工程水量调度带来的效益、工程供水量和实际输水损失, 总结了中线一期工程运行两年来的调水实践及存在的问题, 提出了相应的建议。 The Middle Route of the South-to-North Water Transfer Project has been running safely and the water quality along the line was up to standard in the past two years. The total outflow from Taocha canal headwork is more than 6 billion m3. In order to optimize the real-time water regulation of the Middle Route Project, it is necessary to systematically summarize the water regulation scheme, water regulation plan, and the water regulation practices in the past two years. This paper introduces the water regulation scheme of the project, the annual transferable water volume of Danjiangkou Reservoir, the annual water regulation plan, as well as the water regulation practices of the project in the past two years. It analyzes the water regulation benefits, actual water transfer volume, and water transfer loss of the Middle Route Project. It also reviews the practices of and existing problems in water regulation of the Middle Route Project and proposes corresponding suggestions.
