Abstract：An iterative algorithm was developed to assess the atmospheric environmental capacity governed by air quality targets, based on the third generation air quality model WRF-CAMx and national emission inventory of major air pollutants. The atmospheric environmental capacity of SO2, NOx, primary PM2.5 and NH3 emissions by provinces were calculated with the constrain of annual average ambient PM2.5 concentration standard (GB3095-2012). The results indicated that the national carrying capacity of SO2, NOx, primary PM2.5 and NH3 emissions was 1363.26×104t, 1258.48×104t, 619.04×104t, and 627.71×104t. The actual emissions of SO2, NOx, primary PM2.5 and NH3 in year 2010 were 66%, 81%, 96%, and 52% higher than the carring capacity. The emissions of these four types of air pollutants came from provinces that were severely polluted, such as Henan, Hebei, Tianjin, Anhui, Shandong, and Beijing, were exceeded 100% over its carrying capacity.
