Method and device for simulating spatial distribution of population

The invention belongs to the technical field of geographic information systems, and provides a method and a device for simulating the spatial distribution of population. The method comprises the following steps: acquiring the positioning data of multiple mobile terminals in a scheduled time, wherein the positioning data includes the location of a base station where the multiple mobile terminals are located; mapping the locations of the multiple mobile terminals in the base station to a building scope within the coverage of the base station so as to get the location distribution of the multiple mobile terminals in the building scope; counting the mobile terminals in the building scope according to the location distribution of the multiple mobile terminals in the building scope and a preset spatial resolution; and simulating the spatial distribution of population in the building scope according to the number of the mobile terminals. Through the method and the device, the accuracy of simulation of the spatial di
