为了研究吉林东部暗棕壤在中国土壤系统分类中的归属，采用当前国际土壤分类的主流的土壤系统分类法，以吉林省东部暗棕壤的5个典型剖面为研究对象，通过野外剖面形态特征调查、剖面描述、理化性质分析，研究了土壤的发生特性，确定土体的诊断层与诊断特征，按照《中国土壤系统分类检索（第3版）》的标准，初步确定吉林东部暗棕壤在中国土壤系统分类中归为淋溶土和雏形土2个土纲，冷凉淋溶土和湿润雏形土2个亚纲。

In order to research the belongs of dark brown soil in the east of Jilin Province in the Chinese soil taxonomy, the author used the present mainstream of soil taxonomy method of international soil classification, 5 typical profiles of dark brown soil in the east Jilin Province of China were researched in this study. By field survey, profile description, the physical and chemical characteristics analysis of the soils, the author studied thoroughly the soil genetic, identified diagnostic horizon and diagnostic characteristics, on the basis of the keys to Chinese soil taxonomy (3rd edition), initially identified in eastern Jilin dark brown soil classification of Chinese soil taxonomy as argosols and cambosols 2 soil classes, boric argosols and udic cambosols 2 subclasses.
