The invention discloses a multi-communication network intelligent networking method for intelligent ship navigation, and the method comprises the steps: analyzing the type of ship-shore communicationservice in intelligent ship navigation, grading communication demands according to service features into four grades; analyzing the available communication link performance of an intelligent ship in real time, wherein the available communication link performance comprises coverage, signal strength, transmission rate, time delay and the like; and adjusting the performance of the available communication link along with the change of the communication demands according to the change of the communication demands. According to the method, hierarchical management is carried out on a large number ofship-shore information interaction demands of intelligent navigation of the ship by adopting four grades of control, decision, perception and dynamics, priorities are sequentially 'control ', 'decision', 'perception ' and 'dynamics' from high to low, and a communication task is quantitatively described by using 'priorities, maximum receivable transmission delay, message size and whether four parameters need to be confirmed'.
