摘　　要：对采自三江并流区的26个典型土壤剖面进行了土壤形成条件调查和理化性状分析,依据《中国土壤系统分类检索(第三版)》,鉴定了诊断层和诊断特性,明确了供试土壤剖面在中国土壤系统分类中的归属。检索结果共有6个土纲(富铁土、淋溶土、灰土、雏形土、新成土、潜育土)、11个亚纲、18个土类、19个亚类,并与中国土壤发生分类和国际土壤分类参比基础(WRB)进行了比较。A total of 26 soil profiles typical of the Three Parallel Rivers area, were selected for field investigation of pedogenetic conditions and analysis of physical and chemical properties. Based on the findings, analytical data and the ＂Key to the Chinese Soil Taxonomy （Third edition）＂, diagnostic horizons and diagnostic characteristics of the profiles were identified and attribution of the soils in the soil taxonomy was determined. Results show that the soils could be sorted into six Orders （Ferrisols, Luvisols, Spodosols, Cambisols, Entisols and Gleysols） , eleven Suborders, eighteen Groups and nineteen Subgroups. Correlations and references were made between the Chinese Soil Taxonomy, WRB and the Chinese soil genetic classification.
