In this paper, Beijing was chosen as a representative study area, and the method of pixel information decomposition was taken on the land part. The land cover percentage was extracted. LAI was calculated according to the research on the cover of plant. Based on characteristics of multi-reflecting light, the authors obtained the reflectance of the soil by using the Bi-directional Reflectance Model of Canopy and Soil and taking only one reflectance into account. According to the roughness factor, the soil water content could be calculated based on the relationship between soil reflaction and LAI.
