Abstract
In this paper, the albedo of several common underlying surfaces in the western Sichuan Plateau is tested experimentally and the solar radiation albedo of different underlying surfaces is obtained by analytical calculation. The results show that the surface albedo of grassland, cement brick land, and sandy land is directly related to the instant total solar radiation received on the underlying surface. The greater the total solar radiation received on the surface, the greater the solar albedo is, and vice versa. While the albedo of water surface is negatively correlated with the total solar radiation intensity, that is, the smaller the total solar radiation intensity is, the larger the albedo is, and vice versa. The average albedo of grassland, cement brick surface, sandy surface, and water surface was 0.32, 0.47, 0.49, and 0.33, respectively. The research results fill the gap of basic data of active and passive solar energy applications in plateau area.
