Abstract: With the rapid development of China’s industrialization and urbanization, urban air pollution has become an urgent problem to be solved. Industrial air pollutants in local areas of cities and towns directly harm the health of residents. Under the UNEP initiative, research on urban air pollution has become a main aspect of air pollution research. This paper focuses on the study of atmospheric pollution in small urban areas using GIS spatial analysis and simulation as the methods and the improved Gaussian plume diffusion model as the mathematical principle, based on ArcGIS Engine components and C#.Net. A simulation system platform for the diffusion process of atmospheric pollutants is designed and implemented, which has various functions including dynamic simulation display expression, GIS spatial analysis, spatial data processing, attribute information extraction and simulation result thematic mapping and export. Based on the Fangshan District in Beijing as an example, the dynamic simulation and spatial analysis of pollutant diffusion were conducted using the system platform based on industrial air pollution resource data in the region. The results show that the system provides significant decision-making guidance for effective urban air pollution warnings and the improvement of urban air quality.
