Spatial distributions of pH of the average annual precipitations for two periods (1992 and 2002) were first established using monitoring data and interpolations. RAINS-ASIA model was employed for predicting annual SO2 emission and area of higher emission than critical loading of the local ecosystem for cases with and without emission control. The data and simulation results show that the area of acid rain in Zhejiang will continue to expand due to lower pH of the precipitations,that the SO2 emission rates will stay at a relatively high level for a long period of time even with control,and that the area beyond critical loading would go through a phase of rapid growth up to 2000 before leveling off with a notable time delay in the recovery process.
