摘要:In view of near-ground atmospheric problem, near-ground atmospheric pollution model was established.Because the applicability of analytical solutions is extremely limited for such conditions, and the distributionand transport of pollutants in air are controlled by geographical conditions, numerical techniques are essentialfor air pollution modelling. In this paper, finite differential method is used to establish plane two-dimensionalnumerical model of near-ground atmospheric pollution belt, and truncation errors associated with finite-difference solution of atmospheric pollution were corrected based on the Taylor analysis. The results indicatethat this method provides the references for the forecast of pollutants and the management and evaluation ofair resources.
