In three low mountain areas. including those in Nanjing-Zhenjiang and Yixing-Liyaag districts of Jiangsu Province snd the northeast district of Jiangxi Province, 20 representative soil profiles with perfect data were collected for canonical variate analysis. The computing results show that on the coordinate plane of canonical variate 1 against canonical vartate 2, 90 percent confidence circles of 4 soil great groups classified in accordance with their tonal distribution in three low mountain areas respectively, i.e. basic yellow brown soils and othic yellow brown soils in Nanjinfi-Zhenjiang district, red yellow soils in Yixing-Liyang district and red earths in the northeast district of Jiangxi Province, are overlapped each other, and the points representing the individual profiles in character space illustrate that soil individuals evolve and transit each other gradually. In the three areas, all soil individuals embody the products.of different developing stages.
