By using the land surface observations data of semi-arid climate and environmental observation stations in Lanzhou University(SACOL station) during 2006-2012 and meteorological data of Yuzhong station, the response of land surface radiation budget component to climate fluctuations was analyzed, the interannual variability of surface albedo was studied and the feedback of various parameters of land surface processes for the interannual fluctuations of Loess Plateau climatic background years was discussed. The precipitation type is used to divide the whole year into winter and summer half years in order to get more significant interannual variability and correlation. Results show that the temperature and precipitation trends in recent years match the overall total Loess Plateau warming and drying trend. Soil moisture and temperature of shallow surface show a good response to air temperature and precipitation. The combined effects of climatic factors are the reason of the change of land surface albedo. Based on the study on the winter and summer data, it was found that the correlation coefficient of long-wave radiation components and climatic factors are more relevant than correlation coefficient of short-wave radiation components and climatic factors.
