Abstract:		"In order to cope with heavy haze pollution in China, the Air Pollution Prevention and Control Action Plan including phased goals of the fine particulate matter (PM(2.5)) was issued in 2013. In this study, China's emission inventories in the baseline 2012 and the future scenarios of 2017 and 2020 have been developed based on this Action Plan. Beijing-Tianjin-Hebei (Jing-Jin-Ji) region, one of the most polluted regions in China, was taken as a case to assess the impact of phased emission control measures on PM(2.5) concentration reduction using WRF-CMAQ model system. With the implementation of the Action Plan, the emissions of sulfur dioxide (SO(2)), nitrogen oxides (NO(X))(,) PM(2.5), non-methane volatile organic compound (NMVOC), and ammonia (NH(3)) in 2017 will decrease by36%, 31%, 30%,12%, and -10% from the 2012 levels in Jing-Jin-Ji, respectively. In 2020, the emissions of SO(2), NO(X,) PM(2.5), NMVOC, and NH(3) will decrease by 40%, 44%, 40%, 22%, and -3% from the 2012 levels in Jing-Jin-Ji, respectively. Consequently, the ambient annual PM(2.5) concentration under the scenarios of 2017 and 2020 will be 28.3% and 37.8% lower than those in 2012, respectively. The Action Plan provided an effective approach to alleviate PM(2.5) pollution level in Jing-Jin-Ji region. However, emission control of NMVOC and NH(3) should be paid more attention and be strengthened in future. Meanwhile, emission control of NO(x), SO(2), NH(3) and NMVOC synergistically are highly needed in the future because multiple pollutants impact on PM(2.5) and O(3) concentrations nonlinearly"
