Abstract: According to the estimated emission data for sulfur oxidate, the tendency of sulfur deposition and transport and its influence on soils in future are estimated with three-dimensional Eulerian transport model in East Asia. Results show that the sulfur deposition in East Asia will increase day by day in the next fifteen years. Deposition of some region will be much more than the critical loads of soil. The transport among regions will be larger than before. The situation demands immediate action.
