摘要：In this study, to remove the effects of topography and surface roughness to observed spectrum initially, a method using the normalised reflectance (pseudo- reflectance) was employed. Then, we examined the removal of the vegetation effects (such as green vegetation and dry vegetation) and a method to estimate soil pseudo-reflectance spectrum, because the ground surface shows the mixture of soil and vegetation. Using soil pseudo-reflectance, we estimated the fundamental soil properties such as clay mineral content. The results showed higher accuracy for soil pseudo-reflectance data corrected for green vegetation and dry vegetation effects than reflectance data, which demonstrated the effectiveness of our correction method
