Using the observed data at six automatic stations in the mid- and upper-reaches of HEIFE from June 2008 to May 2009, the seasonal variations of albedo on different underlying surfaces are analyzed. The influences of solar elevation angle, soil moisture, and precipitation on albedo are also studied in this paper. The impact of snow cover on the albedo at Yakou station is discussed. Meanwhile, the soil moisture data are also related to albedo to discuss its influence at Huazhaizi station. The results show that the solar elevation angle in different seasons has different effect on albedo, while its impact is also different on different underlying surfaces. Solar elevation angle on snow surface has the greatest impact on alebdo, and the second is the forest land cover. At  herbage and farmland stations, the solar elevation angle has greater impact on albedo in summer than that  in winter. By analyzing the observed data， the surface soil moisture has a significant impact on albedo. Although sporadic rain can not infiltrate into the ground, it can still cause albedo decrease in a short time because of increasing the surface soil moisture. The different intensity of precipitation has different effect on albedo. According to the average annual albedo, the sequence of albedo at six stations are alpine meadow>desert>herbage>farmland>thin grass>forest, respectivily.
