The invention discloses a ship traffic flow prediction method, system and device and a storage medium, and relates to the technical field of ship navigation. According to the application, the navigation channel network topological graph is established according to the actual navigation channel network to obtain the navigation channel network topological information, the navigation channel network topological information is processed by using the knowledge graph triple to obtain the navigation environment knowledge graph, and then the navigation environment knowledge graph and the ship traffic flow information are processed by using the knowledge graph embedding technology to obtain the ship traffic characteristic information. The ship traffic characteristic information is processed through the gating circulation unit to obtain the traffic time sequence characteristic information, the traffic time sequence characteristic information is input into the graph convolutional neural network for prediction to obtain the traffic flow prediction information considering the traffic space-time correlation and the environmental influence factors, and the accuracy of ship traffic flow prediction is improved.
