By usingreal-time solar radiation and scattered radiation data at the four stations of Beijing,Guangzhou, Shenyang and Wuhan from 1961 to 2003, statistical analyses show thatthe total solar radiation and direct radiation gradually decrease in recent 43 years,and both have positive departure before 1980s by contrast to negative departure after1980s.
对43年的资料进行统计分析，结果表明：近43年来，四个站的总辐射和直接辐射呈逐渐减少的趋势，在80年代以前为正距平，80年代以后为负距平，而散射辐射减少不显著，广州、沈阳甚至有增加的趋势，说明太阳总辐射的下降主要是由直接辐射的变化引起的。
