摘　　要：随着2012,2013年金沙江下游向家坝、溪洛渡水库的建成投运,形成了世界上规模最大的流域梯级水库群-长江干流梯级水库群(溪洛渡-向家坝-三峡-葛洲坝).长江干流梯级水库群防洪库容277亿m^3、调节库容239亿m^3、总装机43835 MW,具有防洪、发电、航运、供水和生态等巨大的综合利用效益.近几年,基于梯级水库群联合蓄放次序调度理论,采用库容效率法对长江干流梯级水库群在联合防洪、蓄水和消落等方面进行了初步探索和实践.结果表明:长江干流梯级水库群的联合调度不仅能充分保障长江流域的防洪安全与淡水资源安全,同时也能有效改善长江流域生态环境,发挥长江航运"黄金水道"的作用,以及进一步提高长江流域水资源利用率,服务国家"西电东送"、"节能减排"能源战略,为促进长江经济带的战略发展发挥重要作用.The largest cascade reservoirs in the world, namely the cascade reservoirs on the mainstream of Yangtze River （CRMYR） which consists of Xiluodu, Xiangjiaba, Three Gorges and Gezhouba reservoirs, have been formed since the completed infrastructure of the Xiangjiaba and Xiluodu power plants in 2012 and 2013, respectively. With the benefits of flood control, power generation, shipping, water supply, ecological environment and so on, the CRMYR has 27.7 billion cubic meters flood control storage, 23.9 billion cubic meters regulating storage and 43835MW installed capacity. The CRMYR is operated and managed by the China Three Gorges Corporation （CTG）. In recent years, based on the operation theory of joint storage and supply orders for cascade reservoir group, CTG carried out a tentative exploration and practice in the field of joint flood control, impounding and water supply for the CRMYR with storgate capacity efficiency method. Results show that the joint operation of the CRMYR is able to not only enhance the water use efficiency, improve the basin ecological environment effectively promote the regional economic and play an important role in Yangtze River Golden Waterway, but also has great influence on the implementation of national clean energy strategy and the development of Yangtze River Economic Zones, while without reducing the safety of the Yangtze River flood control and freshwater resources.
