Waste gas pollution diffusion is one of the basic factors that should be considered in the layout of urban planning. In the field of Chinese urban planning, limited by the planning skill and the level of different departments' involvement, the future pollution degree and pollution range of industrial region is hard to be predicted accurately. The newly issued Urban and Rural Planning Act carry out scientific development idea, pay more attention to the proteaction of urban ecological environment in principles, and encourage the application of new technology and new methods in planning skill. This paper combines digital map information, collects industrial point source spatial data of Nanjing, selects appropriate model from the technical requirements of urban land planning, establish database of air pollution diffusion based on ArcGIS platform, calculates spatial concentration of air pollution diffusion with interpolation, and carry out superposition between 16 wind directions and value in multi-sources air pollution, puts forward the conception of effective pollution range according to national environment management system standard, and performs a preliminary spatial fitting between computing result of spatial data and urban land, evaluates the effects of waste gas pollution in Nanjing on urban land planning. Finally the research direction that can be prolonged is pointed out.
