This paper deals with the physical, chemical, micromorphological, and mineralogical properties of thirteen profiles of soils developed in the southern subtropical region and the central subtropical region in Fujian. The dcgree of allitic weathering, selection of indices for dividing soil groups, and classification of these soils are discussed. These soils are all in the moderate allitic stage, but with more or less different degrees of development. As for the allitic soils which have not yet deeply weathered, kaolinization can reflect the soil development degree to a great extent. Thus, the average kaolinite contents of clays in B horizons have been chosen as the main index for dividing soil groups, and the average silica-alumina ratios of clays in these horizons as the accessory index. All the soils have been divided into two groups. The first is the group of lateritic red earths, of which the average kaolinite contents of clays in B horizons are more than 70%, or the average silica-alumina ratios of clays in B horizons are less than 2.10 when the kaolinite contents are between 60% and 70%. The second is the group of red earths, of which the average kaolinite contents of clays in B horizons are less than 60%, or the average silica-alumina ratios of clays in B horizons are more than 2.10 when the kaolinite contents are between 60% and 70%. The distribution of the two groups soils does nor entirely conform with the zonality.
