Two methods of atmospheric environmental impact assessment for enterprises were discussed in this paper. One was the pollutant contribution rate assessment based on regional maximum value point and sensitive sites, the other was the global pollutant contribution rate assessment method based on all grids in the region. The emission contributions to the atmospheric SO 2 concentrations from the lead zinc smelting enterprise were simulated by AERMOD using 100m scale grids within 25 square kilometres in 2018. The results showed that the change of environmental benefits caused by the increase of chimney height presented different trends by using the two assessment method, and the regional assessment method was disturbed by the terrain factor. The further research should be doing in order to reflect the pollution diffusion of emission contributions better.
