By means of research on correlation between spectral reflectance characteristics of soil and soil physico-chemical properties, and on the basis of law of soil distribution in China, a tentative programme on geographic regionalization of China land background was suggested. The programme was based on plant cover degree and spectral reflectance characteristics of soil. The whole counrty was divided into 6 regions and 23 su'bregions by the programme.
