摘　　要：在江西省选取了由花岗岩、泥页岩和红砂岩发育的46个典型红壤剖面,在明确剖面形态特征及理化性质的基础上,依据《中国土壤系统分类检索(第三版)》确定了其在中国土壤系统分类中的归属,由此讨论了不同纬度带下,红壤与中国土壤系统分类单元参比关系以及气候和母质对所划分出的系统分类单元的影响。结果表明,46个典型红壤共划分为3个土纲、3个亚纲、6个土类和14个亚类,其中江西省纬度28°N以北主要归属于湿润淋溶土,26°N以南主要归属于湿润富铁土,26°~28°N赣中地区,花岗岩发育的土壤主要归属于湿润富铁土,发育于泥页岩、红砂岩的典型红壤主要归属于湿润雏形土。A total of 46 typical Red soil profiles in Jiangxi Province developed from granite, shale and red sandstone were selected, identified and classified with Chinese Soil Taxonomy, and their reference to genetic classification were defined according to their diagnostic layers and diagnostic characteristics. Reference between Chinese Soil Taxonomy and Red soil and the effect of parent materials and weather on soil type were discussed. Results showed that the studied profiles were classified into 3 orders, 3 suborders, 6 groups and 14 subgroups, and the Red Soils in Jiangxi Province were mainly Udic Argosols in the north of 28° N but were Udic Ferrosols in the south of 26° N. From 26° N to 28° N of the central Jiangxi Province, the Red soils derived from granite were mainly Udic Ferrosols and those derived from shale and red sandstone were mainly Udic Cambosols.
