The invention provides a space-based and base-based integrated train positioning method based on a Beidou short message. The method comprises the following steps: acquiring fusion positioning information of a train; under the condition that communication between the train and a ground train center monitoring system is interrupted, the fused positioning information is transmitted to a satellite; transmitting the fused positioning information to the ground train center monitoring system based on the satellite to obtain the positioning information of the train; the fused positioning information comprises satellite positioning information and multi-source sensor positioning information. According to the method provided by the invention, under the condition that the communication between the train and the ground train center monitoring system is interrupted, the fusion positioning information of the train is transmitted to the ground train center monitoring system based on the satellite short message, so that the integrated transmission of the train position information under the emergency condition is realized, and the safe driving of the train is ensured; and high-precision positioning and emergency rescue functions of the train are realized. And moreover, the installation of ground equipment is reduced, and the equipment purchase and subsequent maintenance cost is reduced.
