Numerical simulation of industrial pollution in the Central District of Foshan City.

The central district of Foshan City is considered as the study region.The distribution and emissions of industrial pollution sources are analyzed.On this basis,the diffusion and transmission of SO_2 emitted by industry are simulated using mesoscale meteorological model(MM5) coupled method of air quality model CALPUFF.Considering the internal sources and the peripheral sources,the trend of the simulated mass concentration of SO_2 and that of the observed mass concentration of SO_2 is similar,which indicates the coupled method can simulate the variable features of SO_(2) better.The simulated result of SO_2 emitted by the industry in the central district shows that the distribution of industrial emissions and the meteorological environment have a significant impact on the temporal and spatial distribution of SO_2 emitted by the industry in the central district.
