A coordinated fueling system satisfying thousand-second pulsed plasma discharge, including a gas puffing system, a supersonic molecular beam injection system, an ice pellet injection system, a fusion device, a gas puffing port of a wave antenna, a divertor and a plasma. The gas puffing system, the supersonic molecular beam injection system and the ice pellet injection system are provided at different positions of the fusion device to perform deuterium-tritium plasma discharge in a magnetic confinement fusion device. Through coordination of different moments, positions and fueling methods in plasma establishment and maintenance stages, of the stable thousand-second density control of the fusion device, boundary parameters adjustment of the plasma required for wave coupling and effective control of a heat flux of the divertor can be satisfied. A coordinated fueling method is also provided.
