Abstract: The box model technique was applied to analyse the regional air quality distribution of Beijing's Fengtai district. Using the IDW interpolation and spatial grid statistical method the spatial representation of PM emission of different regions surrounding different air monitoring stations was deduced using GIS to help suggest priority regions for monitoring station installations. The results revealed that the main source of PM₁₀ emission in the region was the industrial and commercial areas, both exhibiting values higher that the annual PM₁₀ concentration standard (50 μg/m³). The spatial analysis also revealed that the total PM₁₀ concentration frequency variation exceeded standard in regions around Fengtaihuayuan monitoring station making it a priority region for monitoring station installation. With this analysis proving to be highly significant in optimising several PM₁₀ monitoring layouts, the described approach represents a useful tool for regional administrations to plan and apply air pollution reduction goals in a region.
