摘　　要：对皖南不同时期紫红色砂石岩上发育的8个土壤剖面,按中国土壤系统分类体系,进行鉴别、检索、分类定名。阐述发生分类紫色土的2个亚类级土壤类型在中国土壤系统分类中归为3个土纲,即均腐土、雏形土和新成土;3个亚纲,即湿润均腐土、湿润雏形土和正常新成土;4个土类和6个亚类。提出按中国土壤系统分类的紫色土分类系统;并与美国土壤系统分类、国际土壤分类参比基础进行了参比。讨论了皖南紫红色砂石岩上发育为均腐土的成土环境条件,同时对发生分类紫色土在中国土壤系统分类类别检索提出修订建议。Eight soil profiles in soils derived from purple-red sand rocks at different time periods in south Anhui Province were identified and classified according to the keys to the Chinese Soil Taxonomy （CST） （the 3rd edition）. The placement of 2 taxa, the eight soil profiles were formerly sorted into on the subgroup level in the Chinese Soil Genetic Classification （CSGC）, in CST was elucidated in the paper. All these soils studied are classifed into 3 CST Orders： Isohumosols, Cambosols and Primosols, 3 CST Suborders： Udic Isohumosols, Udic Cambosols and Orthic Primosols, 4 CST Group and 6 CST Subgroups. With CSGC- Purple-Soil as object for classification, references between the CST, the U. S. Soil Taxonomy （ST） and the World Reference Base for Soil Resources （WRB） were discussed. Environmental conditions for development of Isohumosols from purple-red sand rocks in south Anhui Province were also studied. Meanwhile some amendments were suggested of the Keys to the CST in classifying CSGC-Purple-Soils
