为了解冀北山地土壤发生学分类代表性土类-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 classification of soil taxonomic representative soil types - brown earth and brown soil in mountainous areas of north Hebei Province, the authors investigated the morphological characteristics of field profiles and their physico-chemical properties in northern mountain areas of Hebei Province. Two brown earths, Based on the occurrence characteristics of three cinnamon soil profiles, the diagnostic layers and diagnostic properties of each soil profile were determined according to “Soil Taxonomic Classification (3rd Edition) of China”, and their ownership in soil taxonomy of China was determined by searching. The results show that the five representative soil profiles in the mountainous area of ​​Hebei Province belong to three soil classes (embryonic soil, newly formed soil and leaching soil), three subclasses, four soil types, four soil types Subclass. At the same time, the classification of soil basic unit of five representative sections in the area was discussed. Five soil groups and five soil series were initially drawn.
