未来东亚地区硫化物沉降及输送的预测

Estimation of Sulfur Deposition and Transport in China and East Asia in Future

采用东亚未来二氧化硫排放量的预测资料，利用东亚硫化物输送模式拟了未来１５年东亚各地区的硫化物沉降量、相互输送量的变化趋势力其对土壤的影响。结果表明，未来１５年东亚各地区的硫化物沉降量将日益增多，一些地区硫化物沉降量大大超出了土壤对酸沉降的承受能力，对周边地区硫化物的输送量也将进一步加大，形势相当严峻。

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.
