In order to invert the soil moisture content and analyze the influence of soil moisture content on the bidirectional reflectance, the parameters of bidirectional reflectance model are obtained based on the multi-angle hyper spectral data in the field, and the soil moisture content using the calculated values is inverted. The relationship between model parameters in three wavelengths and different directions and moisture content is analized, the differences of inverting soil moisture content results based on model in different directions are found, and the inverting accuracy is stablest at 865 nm. The result suggests that based on the bidirectional reflectance distribution characteristics, the soil moisture content can be inverted with high accuracy. At the same time, the effect of the directional reflectance on the inversion accuracy should also be considered.
