A wide range of natural soils in southern China were collected to study the characteristic variation and to develop a quantitative approch of soil spectral reflectance which are related to soil classification and some soil properties. A total of 81 soil samples was collected froxtn A or B horizon in 42 soil profiles which involve five main soil great groups, i.e, latosol, red earth, yellow earth, paddy soil and purplish soil. The reflectance of air-dried soils over range of 0.36-2.5μm wavelength by using a HIACTHI 340 model spectrophotometer in the liboratory.
