| 摘 要： | 采用《中国土壤系统分类（第三版）》和《中国土壤系统分类——土族与土系建立原则与标准（试用稿）》对冀北地区7个盐碱化土样进行了分类,共划分了4个土纲,6个亚纲,6个土类,7个亚类,建立了平地脑包系等7个土系。研究结果表明,系统分类亚类与发生分类亚类参比并无对应关系;部分盐碱化土壤并未在系统分类高级单元中体现盐碱特征,而在基层分类中对盐分含量和积累位置进行补充,表明系统分类的划分指标要求更严格,分类更标准。最后讨论了盐碱化土壤诊断层、诊断特性和土壤分析方法的确定等问题。

| Abstract: | According to the "Chinese Soil Taxonomy ( 3rd ed) " and " Principles and Criteria for Establishment of Soil Family and Soil Series of Chinese Soil Taxonomy (The trial version) ", the 7 types of salt-affected soils in North Hebei were classified into 7 newly established soil series, under 7 Subgroups, 6 Groups, 6 Suborders and 4 Orders. Results show that referencing comparison between CST and CSGC at the subgroup level did not find that they had any correspondences in CSGC; the classification of some of these soils in CST did not reflect any characteristics of salinity or alkality in their respective higher-level unit, while some amendments had to be made to salt content and position of salt accumulation for classification at the base level, which indicates that the criteria for sorting in the soil taxonomy are stricter and more standard. Besides, issues like diagnostic horizons, diagnostic characteristics and soil analysis methods for classification of salt-affected soils were discussed. |
