摘要：

利用中国最新公布的截至2008年华东地区13个站点资料，对华东地区平均的地面太阳总辐射长期变化趋势进行了分析，并讨论了该地区云、气溶胶和水汽对地面太阳总辐射变化的影响。研究表明，1961~2008年华东地区平均总辐射呈现减少趋势，减少速率为2.05 W•(m2•10yr)-1；1990年前该地区总辐射呈现出显著的下降趋势， 1990~1995年呈现快速增加趋势，但是1995~2000年再次呈下降趋势，2000年后在平均线上下波动略有增加。气溶胶、云和水汽对华东地区地面太阳总辐射的长期变化都有一定的影响，但是在不同的时段影响程度不同，在1961~1989年总辐射的减少主要归因为气溶胶的增加；而在1990~1999年和2000~2008年则是以云量的影响为主，而且低云量对地面总辐射的影响要大于总云量的影响。

Abstract:

Based on updated daily surface solar radiation and associated meteorological elements data from 13 observational stations over South China, the long term trend of surface total solar radiation was analyzed, and the influence of cloud, aerosol and water vapor on total solar radiation were explored. The total solar radiation decreased during 1961-2008 at a rate of 2.05 W/(m2•10yr); it decreased obviously from 1961 to 1989, and increased from 1990 to 1995, but decreased again since 1995, after 2000 fluctuated in the average line and slightly increased. the change of aerosol, cloud and water vapor contribute much to the variation of total radiation, from 1961 to 1989, the results imply that the atmospheric aerosols burden enhancement is the major reason for global radiation reduction, while cloud cover’s contribution is relatively larger from 1990 to 2008, and the influence on total solar radiation of the low cloud is greater than that of the total cloud.
