Abstract In order to evaluate the effect of the total SO2 and NOx emissions control on the decrease of acid deposition, we analyzed the trends of sulfur deposition and nitrogen deposition on the basis of the throughfall from 2011 to 2016 at Tieshanping catchment, Chongqing. The sulfur deposition significantly reduced from 6.70kmolc/(hm2·a) in 2011 to 2.34kmolc/(hm2·a) in 2016. In comparison, the nitrogen deposition did not have obvious decrease, with the values of 2.41kmolc/(hm2·a) and 2.11kmolc/(hm2·a) in 2011 and 2016, respectively. Therefore, although the total acid deposition has declined in Chongqing, the control of nitrogen deposition still need to be strengthened.
