Abstract
This article discusses the regional atmospheric environmental capacity of areas in different stages of economic development, and presents the Beijing-Tianjin-Hebei (Jingjinji) region and the five northwestern provinces and autonomous regions in China as examples. The atmospheric environmental capacities for sulfur dioxide (SO2), nitrogen oxides (NOx), fine particulate matter (PM2.5), volatile organic compounds (VOCs), and ammonia (NH3) emissions were calculated for the various provinces with the constraint condition of the annual average ambient PM2.5 concentration standard (GB3095—2012), using a global chemical transport model from the Goddard Earth Observing System (GEOS-Chem). The results indicate that the total emissions of SO2, NOx, primary PM2.5, VOCs and NH3 emited from the Jingjinji and the five northwestern provinces and autonomous regions all exceed the environmental capacity.
