摘　　要：选取位于河南中西部褐土土类的7个典型单个土体作为研究对象,通过土壤剖面形态特征和理化性质的分析,确定了它们在中国土壤系统分类中的位置。按照《中国土壤系统分类(第三版)》诊断标准,供试剖面中诊断出包括黏化层、钙积层、雏形层、氧化还原特征、温性土壤温度状况、半干润土壤水分状况等诊断层和诊断特性,7个剖面中,4个划归淋溶土纲,3个划归雏形土纲;按照土族和土系划分标准建立了杨岭系、诸葛系等7个土系。从高级分类单元和基层分类单元分别对7个土壤进行发生分类与系统分类之间的参比。此外,在高级分类单元级别上进行了中国土壤发生分类、中国土壤系统分类、美国土壤系统分类和世界土壤资源参比基础之间的参比研究,并建议中国土壤系统分类中新增"钙积干润雏形土"土类。Seven typical soil profiles of cinnamon soil in Central and Western in Henan Province were selected as study objects to determine the attribution of 7 soil profiles in Chinese Soil Taxonomy(CST) by comparing their physical properties and chemical properties. With reference to “Chinese Soil Taxonomy(3 rd edition)”,the studied soil profiles were found to have the following diagnostic horizons and characteristics: Argic horizon,Calcichorizon,cambichorizon,Calcicevidence,Redoxfeatures,Calcaricproperty,Ustic soil moisture regime,Udic soil moisture regime,Aquic soil moisture regime,Mesic soil temperature regime,Thermic soil temperature regime. Of the 7 soil profiles,4 soil profiles were classified into Argosols and 3 soil profiles were classified into Cambosols. With reference to “Criteria for Establishment of Soil Family and Soil Series in Chinese Soil Taxonomy”,7 soil series like Yangling soil series and Zhuge soil series were established. And the reference between the Chinese Soil Genetic Classification and the Chinese Soil Taxonomy was made from higher taxon level and basic higher taxon level respectively. In addition,the reference study among CSGC,CST,WRB and ST was carried out at the higher taxon level. It is also suggested that the Group of “ CalciUstic Cambosols ” should be added to the CST.
