Attribution of Soils in Handan Yongnian in Chinese Soil Taxonomy
To study the characteristics of pedogenesis and types attribution of soils in Yongnian District of Handan City, the 3rd National Soil Survey was carried out in the district in 2022. A total of 616 surface soil samples and 20 soil profiles were collected, 6 typical soil profiles were selected as the study subjects, and the position of each soil body in the Keys to Chinese Soil Taxonomy (CST) was determined through the analysis of soil profile morphological characteristics and physical and chemical properties. According to the classification search results of CST, it was found that the diagnostic layers in the test profile included ochric epipedon, cambic horizon, and argic horizon, and the diagnostic features included redoxic features, calcaric property, lithologic characters, soil temperature regimes, and soil moisture regimes. In CST, the studied soils were belonged to 3 orders of primosols, argosols, and cambosols, 4 suborders, 4 groups and 4 subgroups; meanwhile, 5 soil families and 6 soil series (Zhaili series, Jiyao series, etc.) were established of the selected soil profiles. The reference between pedogenesis and system classification of 6 soils profiles was conducted from high and base taxon. It provides a precedent for carrying out the soil survey and soil system classification work in Handan City.

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。
