The invention discloses a space-ground integrated network dynamic and static hybrid routing method, which aims to provide a method that adapts to the continuous dynamic change of the space-ground integrated network topology, the load capacity of the node star is limited, the transmission time of the inter-satellite link is prolonged, and the distribution of the carrying data flow A hybrid routing method that integrates dynamic and static features such as imbalance. The present invention is realized through the following technical solutions: the static road sends the motion trajectory information of the satellite-based nodes to the ground operation and maintenance management and control center, initiates a routing request, and obtains the motion trajectory information of the satellite-based nodes; the operation and maintenance management and control center adopts a time-virtualized routing algorithm, Carry out time slice division, virtual topology map construction and original routing table creation; satellite-based nodes respond to routing requests, and after accepting tasks, construct task routes according to static routing tables, obtain on-board load tasks, and judge whether sending data packets is successful. If it fails, the DSR routing algorithm is used to dynamically reconstruct the route. If the data packet is sent successfully, the data packet transmission is completed.
