Atmospheric pollution source spatial layout simulation method based on WRF-CALPUFF model

The invention discloses an atmospheric pollution source spatial layout simulation method based on a WRF-CALPUFF model, and the method comprises the following steps: obtaining global 1-degree meteorological analysis data, terrain and land utilization data and objective observation data of a target research region, and processing the obtained data into meteorological data with a certain temporal-spatial resolution based on the WRF-CALPUFF model; dividing a target research area to generate equal-interval grid units corresponding to actual precision, and then converting the equal-interval grid units into a virtualized point source emission list; and simulating and calculating the contribution degree of the atmospheric emission source of each grid unit to the urban or regional air quality in batches. According to the method, the CALPUFF source codes are recompiled, so that contribution degree simulation calculation can be synchronously carried out on hundreds of air quality stations, quantitative evaluation suppor
