%X The main points of soil mapping method discussed in this paper are as follws: 1. The visual intepretation is made by using the standard false color and analogous natural color pi--ctures composed from TM original images and the reflective spectral data of ground objects are consulted to analyse the characteristic of their image tone; 2. The spectral characteristic of ground objects is found out through contrast interpretation of the black and white TM images of the seven bands and the effect of color composite is predicted; 3. The information of ground thermal field and soil vertical zonality which differ with elevation is extracted by using the TM6 thermal infrared image to make the pseudo-color-equidensity slicing; 4. The information of soil and land utilization is enhanced by using TM ratio images and their false color composition; and 5. The related data, such as topographical maps and geological maps, are consulted to draw the soil map. Experience has proved that the precision of the soil map on the middle scale drawn by this method is up to the standard requivement, the boundaries of some soil categories interpreted and delineated by the method are more objective and precise, and the amount of mapping work is greatly reduced.
