Different air pollution control zones had different air pollution allowable pollutant increase limits(APIL). In the study, APIL would be tested with CALPUFF model, and the result of simulations would be the reference for establishing criteria of APIL in the future. This research was divided into three cases to test APIL. In CASE1, the pollutant emissions reached a certain scale, and the result of simulations was consistent with the law standard. CASE2 and CASE3 simulated the increment of secondary particulate matter concentration by the sum of sulfur oxides and nitrogen oxides, and took the date which daily average concentration increment was greatest as case date to discuss and analyze. The result of simulations showed that the increment of secondary particulate matter could be 11~18% of the law standard when the stack height was twenty-five meters and sum of sulfur oxides and nitrogen oxides were one thousand tons and the phenomenon of traverse regions transportation existed. If the quantities of primary and secondary particulate matter were considered at the same time, the pollution condition would be worse. This result would also reflect the defect not formulating the amount of the primary particulate matter in the air quality modeling and simulation draft.
