AB  - The Chinese government has established compulsory targets to reduce sulfur 
      dioxide (SO2) and nitrogen oxide (NOx) emissions by 8% and 10%, respectively, 
      during 2010-2015. In this study, the effect of the policy was evaluated by 
      predicting the recovery of acidified forest soil in Chongqing, an area severely 
      impacted by acid rain in southwest China. Since precipitation has decreased 
      significantly in this area in recent years, the impact of drought on soil 
      acidification was also considered. A dynamic acidification model, MAGIC, was used 
      to predict future trends in soil chemistry under different scenarios for 
      deposition reduction as well as drought. We found that the current regulation of 
      SO2 emission abatement did not significantly increase soil water pH values, the 
      Ca2+ to Al3+ molar ratio (Ca/Al), or soil base saturation to the level of 2000 
      before 2050. NOx emission control would have less of an effect on acidification 
      recovery, while emission reduction of particulate matter could offset the 
      benefits of SO2 reduction by greatly decreasing the deposition of base cations, 
      particularly Ca(2+). Continuous droughts in the future might also delay 
      acidification recovery. Therefore, more stringent SO2 emission control should be 
      implemented to facilitate the recovery of seriously acidified areas in China.
