This invention discloses a ship dual-mode communication method and terminal based on adaptive region awareness. Multiple data points are input into a preset clustering model for cluster matching. If an existing cluster is matched in the preset model, the center and boundary information of the existing cluster are updated. Location point information is acquired and matched with all boundary information. If a match is successful, a region type signal is generated based on the matched boundary information; if a match fails, an unknown region signal is output. For region type signals, the target ship is controlled to use mobile communication and / or satellite communication; for unknown region signals, the target ship is controlled to use mobile communication for region signal analysis. This invention constructs a region signal model based on historical experience, enabling forward-looking decision-making, reducing the average energy consumption of the dual-mode communication terminal overall, improving the endurance of the ship terminal in open seas or areas with weak coverage, and ensuring communication reliability.
