Abstract It is undoubted there are some interdependent relationships between rock and soil,on either their compositions or spectrum.The paper analysis lab.reflectance spectrum(0.4~2.5μm) of soils and their parent rocks from the Western Qinling area.In the respects of spectral evolution of parent rocks and soils,during different weathering period and between different soil layers,also the effect of organic and ferric oxide matter to spectrum are discussed.It is important for remote sensing to identify the underlying rock and alteration,through spectrum of their soils.
