Abstract:Prediction scenarios by implementation of both 2003-version emission standard and 2011-version emission standard were set up. Nitrogen deposition and sulfur deposition of both scenarios in 2015 were simulated using Models- 3/CMAQ to investigate the regional air quality improvement by the 2011-version emission standard. The results showed that the 2011-version emission standard can effectively improve sulfur deposition condition in China. Compared with the implementation results of 2003-version emission standard, by 2015, sulfur deposition in China mainland would be reduced by 18.58%, and the area with annual sulfur deposition higher than 3.2t/km2would be reduced by 86.40%, respectively. The 2011-version emission standard can improve nitrogen deposition condition in China to some degree. Compared with the implementation results of the 2003-version emission standard, by 2015, nitrogen deposition in China mainland would be reduced by 9.28%, and the area with annual nitrogen deposition higher than 4.0t/km2would be reduced by 27.27%, respectively.
