【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.
[Abstract]:With Xiangjiaba in the lower reaches of Jinsha River and Xiluodu Reservoir completed and put into operation in 2012 and 2013, the cascade reservoir group of the Yangtze River main stream (Xiluodu-Xiangjiaba-three Gorges-Gezhouba) formed the largest cascade reservoir group in the world. The flood control capacity of the cascade reservoir group of the Yangtze River is 27.7 billion mm3, the regulating capacity is 23.9 billion mm3, and the total installed capacity is 43835 MW. It has great comprehensive utilization benefits such as flood control, power generation, shipping, water supply and ecology. In recent years, based on the theory of cascade reservoir group combined storage and discharge order operation theory, the reservoir capacity efficiency method has been applied to the preliminary exploration and practice of combined flood control, water storage and decline of cascade reservoirs in the main stream of the Yangtze River. The results show that the combined operation of cascade reservoirs in the main stream of the Yangtze River can not only fully guarantee the safety of flood control and freshwater resources, but also effectively improve the ecological environment of the Yangtze River Basin and bring into play the role of "golden waterway" in the Yangtze River navigation. Further improving the utilization rate of water resources in the Yangtze River basin, serving the national energy strategy of "sending electricity from the west to the east" and "saving energy and reducing emissions" plays an important role in promoting the strategic development of the Yangtze River economic belt.
