The invention discloses a zone area general survey mobile terminal based on GPS and UWB and a positioning method. The mobile terminal comprises a GPS module, a UWB module, a data acquisition module, a data storage module, a communication module, a central processor and a touch screen. The data acquisition module is used for acquiring data of voltage, electric quantity, frequency, device unit account and a picture of a zone area. The data storage module is used for storing the data of the voltage, the electric quantity, the frequency, the device unit account and the picture of the zone area. The communication module is used for carrying out data exchange with the zone area, and uploading the data to a main station, thereby achieving analysis of the data of the zone area. According to the invention, by use of a mixed positioning method where the GPS positioning mode is adopted in the outdoor environment, and the GPS positioning mode is switched into the UWB positioning mode in the indoor environment, so the two modes can be automatically switched according to intensity of signals; seamless connection is achieved; and indoor high precision positioning and outdoor high precision positioning are achieved simultaneously.
