为了解冀北山地土壤发生学分类代表性土类一棕壤、褐土在中国土壤系统分类中的归属,在冀北山地通过野外剖面形态特征调查、理化性质分析,研究了2个棕壤、3个褐土剖面的发生特性,按照《中国土壤系统分类检索(第3版)》确定了各土壤剖面的诊断层和诊断特性,通过检索确定它们在中国土壤系统分类中的归属.研究结果表明:冀北山地5个代表性土壤剖面在中国土壤系统分类中归属于3个土纲(雏形土,新成土,淋溶土),3个亚纲,4个土类,4个亚类.同时探讨了该区5个代表性剖面的土壤基层分类单元的划分,初步拟定了5个土族、5个土系.%In order to understand the belongs of representative genetic soils-brown soil and cinnamon soil in the north of Hebei province in Chinese soil taxonomy, 2 brown soil and 3 cinnamon soil profiles in the north of Hebei were researched in this paper. By field investigation, profile description, analysis of physic and chemical properties of soils, soil genetic characteristics were studied. On the basis of the keys to Chinese soil taxonomy (3rd edition) , the authors identified diagnostic horizons and diagnostic characteristics of the profiles and determined the belongs of the profiles in taxonomy. Results show that- 5 representative soil profiles in the north of Hebei province could be sorted into 3 soil orders (Cambisols, Entisols, Luvisols),3 suborders,4 groups,4 subgroups. In addition, the paper studied soil families and soil series of 5 representative soil profiles and firstly decided 5 families and 5 series here.
