Surface albedo is widely used in the study of energy balance at the Earth's surface, weather forecast, and the study of global change and water circulation. Different land surface features and land cover conditions can cause the anisotropy of surface albedo distribution. It is useful to derive surface albedo over a large area using remote sensing technique. In this work, different band integration approaches were exploited to retrieve the surface albedo over the upper reaches of Tarim River. The relationship between land surface albedo and land use type was quantified by taking the particularity of the basin's geography character into account.
