Dry deposition and wet remove of sulfur from main power plants plan to build in Henan province of China were numerically simulated with CALPUFF based on estimated SO2 emissions of each plant. The results of simulation shows that, the highest grid point annual dry deposition and wet remove quantity of sulfur from power plants reaches 554.498kg/km2 and 457.745kg/km2 respectively. Annual dry deposition and wet remove of sulfur in Henan region can reaches to 8381.422 ton and 4974.747 ton respectively. Zhengzhou was the most heavily impacted city by dry deposition and wet remove of sulfur from power plants, and annual flux of dry deposition and wet remove can reach to 366.953kg/km2 and 188.743kg/km2 respectively. After the completion of construction of new plants and the closing down of old ones, dry and wet deposition in most region of Henan Superscript textprovince declined, and 4642.220 ton of dry deposition and 2405.216 ton of wet deposition were lessened annually according to the simulation.
