The atmospheric environmental capacities of SO2 on representative days over Lanzhou are estimated using the numerical models RAMS, HYPACT and a linear programming model, according to the national ambient air quality standard of China （NAAQSCHN）. The results show that the fields of meteorological elements and SO2 simulated by the models agree reasonably well with observations. The atmospheric environmental capacity of SO2 over Lanzhou is around 111.7 × 10^3 kg d^-1, and in order to meet the air quality level Ⅱ of the NAAQSCHN, SO2 emissions need to be reduced by 20%.展开更多

The results showed that atmospheric environment capacities of SO2,NO2 and PM10in Shennongjia Forest District were respectively 6 268. 8,17 666. 2 and 2 279. 5 t / a,much larger than emissions of air pollutants in Shennongjia in 2012.展开更多
