Abstract：According to the actual situation, this paper studies air pollution problem about PM2.5 in the air. First of all, establishing a multi-dimensional reaction diffusion equations of PM2.5 with initial conditions; Secondly, the use of Fourier transform can obtain the solutions of reaction diffusion equation with initial conditions, which is the common method in partial differential equation; Finally, the PM2.5 diffusion on the horizontal and vertical surface can be obtained by the MATLAB programming. And the PM2.5 density with the changes of time can be learned at the same time.
