Abstract：The six reservoir hydropower stations of Wudongde,Baihetan,Xiluodu,Xiangjiaba,Three Gorges,and Gezhouba are distributed successively along the mainstream of the Yangtze River,forming a cascade that constitutes the world's largest clean energy corridor:the Jinsha River Downstream-Three Gorges Cascade Hydropower Corridor.From the perspective of systems science,this paper first reveals the essence of the corridor as an open,complex,and large-scale system,deconstructing its core components,including the engineering,natural,and social subsystems,and explaining its typical characteristics such as external randomness,structural complexity,and functional diversity.Second,focusing on the"large systems"of the water resources,power,and ecological domains,it defines the corridor's major functional roles as the backbone of flood control and safety,the cornerstone of energy supply security,and the main force in ecological protection,and elaborates on its comprehensive benefits for"overall safety".Finally,from the three dimensions of monitoring and perception,forecasting and prediction,and operation and scheduling,the paper reviews key technologies in the operation and dispatching of the corridor,analyzes the main technical challenges under new circumstances,and proposes corresponding countermeasures.The study provides a reference for promoting the high-quality development of the Jinsha River Downstream-Three Gorges Cascade Hydropower Corridor and for supporting national water,energy,and ecological security at a higher level,across broader fields,and on a larger scale.
