Abstract: The regularity of the distribution of higher categories in Chinese Soil Taxonmy(CST)were studied through analyzing the diagnostic horizons and characteristics and the variation of soil forming factors in China. The results indicate that the distribution regularity of higher categories in CsT is different for that in the past zonal classification, which is inferred on the basis of typical profiles and bioclimatic conditions. Among the 14 soil orders available in CST, 6 belong to the basic types, which shaw the regularly continuous distribution, and can be deduced into three larger groups: aridic, ustic and udic. The other 8 soil orders belong to the special types with the band-shaped, spot-shaped, chessboard-shaped, patch-shaped distributions and so on. Moreover, there is the regularity of vertical distribution in mountains.
