长江流域干支流已建和在建的大型梯级水库群规模庞大，实施联合调度将对长江防洪安全、水资源优化配置和水电能源高效利用意义重大。对长江流域大型梯级水库群联合调度需要解决的主要理论、方法、技术和管理问题进行了归纳剖析，并结合近年来开展的相关科研工作，简要介绍在大型梯级水库群联合调度的发展战略、优化模型、生态调度、管理体制和仿真平台等方面的主要成果和研究进展。

The joint operation of large-scale cascade reservoirs in the Yangtze River basin will not only strengthen the flood control capability, but also bring great integrated benefit to water resources utilization and hydropower output due to their  tremendous storage capacity and hydropower installed capacity. The key  issues in the development, running and management of joint operation system are proposed. According to researches performed in recent years, research achievements and progresses with respect to the developing strategy, the multi-objective optimization model, the ecological operation, the management system and coordination mechanism, and the system simulation technology for the joint operation of large-scale cascade reservoirs are presented.
