PM2.5 concentration target acquisition method and device

The invention discloses a PM2.5 concentration target acquisition method and device, and belongs to the technical field of environmental protection and air pollution prevention and control. The PM2.5 concentration target acquisition method comprises the following steps: acquiring scene information of a plurality of target years; calculating a target year concentration prediction value under the at least one target year scene information; constructing an atmospheric pollution source emission list under the scene information of at least one target year; performing model simulation by using the atmospheric pollution source emission list under each target year scene information, thereby obtaining a simulation concentration prediction value corresponding to the atmospheric pollution source emission list under each target year scene information; and fusing the target annual concentration predicted value and the simulated concentration predicted value to obtain the PM2.5 concentration target.
