The invention discloses a big data visualization-based wargame inference system. The system comprises a data acquisition system, an information network, a server cluster, a database, a basic database, an inference system library, a model library, a plan library, a command library and a big data output terminal, wherein the data acquisition system is used for acquiring detailed data of belligerents and storing the data into the database through the information network; the database comprises the basic database, the inference system library, the model library, the plan library and the command library; and the server cluster is used for carrying out wargame inference through data in the basic database, the inference system library, the model library, the plan library and the command library and outputting the inference result to users through the big data output terminal. According to the system, the detailed data of the belligerents is acquired through the data acquisition system and the stored into the database through the information network, and then wargame inference is carried out by the server cluster through the data in the basic database, the inference system library, the model library, the plan library and the command library.
