Based on the pollution source emission data of an iron and steel enterprise in Liaoning Province,Busi-ness-As-Usual(BAU)scenario and after the implementation of capacity replacement scenario were established.The CALPUFF model was used to simulate the influence of various pollutant emissions of the steel plant on the atmospher-ic environment protection zone and health protection zone settings around the plant under two scenarios.The results showed that the implementation of the capacity replacement project of iron and steel enterprises had a significant ef-fect on the reduction of major pollutants.Among the major pollutants,emission of particulate matter,SO2 and NOX were reduced by about 53.4%,16.2%and 50.9%,respectively.After the implementation of the capacity replace-ment project,the atmospheric protection distance and health protection distance in the surrounding area of the steel plant were reduced compared with BAU scenario.
