中文摘要：

采用ATMOS长距离传输模型，对2005、2010年全国燃煤电厂排放的SO2的传输及转化过程进行数值模拟。借助于地理信息系统软件和其它工具软件，结合实际监测结果详细分析了整个模拟范围内特别是中国大陆陆地面积上的总S沉降、干／湿S沉降分布特点。

英文摘要：

The ATMOS long-distance transmission model was applied to simulate the transmission and transformation processes of SO2 emitted by coal-fired power plants of China in the years of 2005 and 1010. By using the GIS software and other tools, the distribution characteristics of the total sulphur deposition and the dry/wet sulphur deposition on Chinese main land are analyzed based on real data acquired.
