Abstract：The surface radiation data (1993-2013) from 16 meteorological stations in 15 provinces of China is applied to analyze the change patterns of surface solar radiation in different region of China in resent 20 years,and diffuse coefficient (the ratio of diffuse radiation and direct radiation) with the linear trend estimation method.Results showed that during 1993 2013 surface solar total radiation increased in western and northeast China,but decreased in middle and eastern China.Direct radiation decreased in most of China except for middle part of China,while diffuse radiation and diffuse coefficient increased in most of China except for Urumqi and Lanzhou.The diffuse radiation was the most in southeast China,and lest in northwest China (Urumqi).The diffuse coefficient was the bigger in central and eastern China.
