摘　　要：利用2004年1月-2009年10月的SCIAMACHY卫星对流层S02垂直柱浓度数据产品，选取了4个典型的SO2浓度高值区，从空间分布、年际变化、季节变化、奥运会前后变化几个方面，对我国对流层SO2的时空分布及变化趋势进行了分析，并分析了造成这种分布特征的可能原因。结果表明，我国对流层大气中SO2的分布及变化主要受人类活动的影响，这种影响使得我国SO：的时空分布具有明显的地域性、季节性特征，且显著受到人类硫排放控制措施的影响。The data products of monthly average tropospheric SO2 vertical column densities from Janualy 2004 to October 2009 over China are acquired from the SCIAMACHY instrument on ENVISAT. Selecting four typical SO2 high concentration regions, the spatial-temporal distribu-tion and variation trend of tropospheric SO2 in China were analyzed from aspects of spatial distribution, annual variation, seasonal variation and variation before and after Olympic Games, the reasons for the distribution characteristics were analyzed. The results showed that human activi- ties play a key role in the distribution and variation of tropospheric SO2. The influence results the temporal-spatial distribution of tropospheric SO2 in China has a feature of regional, interannual and seasonal variety.
