摘　　要：利用中国94个气象站提供的辐射观测数据对3个主要的太阳短波辐射卫星产品进行质量评价,选择准确度较高的CERES-EBAF数据并结合MODIS数据,分析中国10 a地表太阳辐射的时空变化特征,并对其影响因素进行初步分析。结果表明:青藏高原高寒生态区始终是地表太阳辐射的高值区,而四川东部和重庆等地组成的川渝生态地区是"低值圈";月均地表太阳辐射受季节变化影响明显,在四季均呈现先增后减的变化特征;2003~2012年期间,我国地表太阳辐射呈现出先增后减的年际变化特征,10 a来,华北生态地区增加最多,为13.50%(+21.33 W/m2),华南生态地区减少了14.27%(-21.56 W/m^2);相比水汽含量,总云量可能是引起中国地表太阳辐射变化的主要因素。The quality of three satellite derived surface shortwave radiation data-sets were evaluated by themeasurements of 94 meteorology stations in China,and it turned out that CERES-EBAF data is of higher accuracy thanthe others. Spatio-temporal variations of solar radiation and its correlations with other factors were analyzed for 10 yearsfrom 2003-2012 based on CERES-EBAF and MOD08_M3 product data. The main findings are：Tibetan Plateau is thehigh value area of the surface solar radiation every year,while the Sichuan Basin and Chongqing area are in＂low valuecircle＂;Seasonal change is obvious,and it is characterized by increasing firstly and then decreasing in one year;During2003-2012,annual surface solar radiation has increased firstly and then decreased in China. Surface solar radiation overNorth China ecological region has increased by 13.50 %（＋ 21.33 W/m^2）for those 10 years,while Southern Chinaecological region has decreased by 14.27 %（-21.56 W/m2）;Correlation-analysis showed that the change of total cloudamount may be the main reason for the change of surface solar radiation in the 10 years.
