The invention discloses an air-ground ACARS message transmission method and system based on file transmission, relates to the aviation data transmission field. According to the technical scheme, the method comprises the steps that before ACARS message block transmission, a sending end sends a Multi-block_Transfer_Req message to negotiate with a receiving end about the size of the message and the effective time of message transmission in a network; and the receiving end makes the following response to the multi-block transmission negotiation requested by the sending end according to the storageresources: sending a Multi-block_Transfer_Abort_Req message to refuse to carry out multi-block message transmission; or, sending a Multi-block_Transfer_Accept message to accept a plurality of messagetransmission requests, and specifying the minimum sending interval time between the message blocks, so that the problems of invalid transmission, waste of network resources, relatively low channel utilization rate, channel ov
