    摘要:

    通过美国《土壤系统分类检索》第9版与第8版和《土壤系统分类》第2版的比较,概括其最新进展:3个诊断土层和2个诊断特性作了修订;高级分类级别增加4个亚纲、12个土类、42个亚类,主要是永冻Gel-土类;土族土系具强烈对比的颗粒大小级别鉴别特征增3个去1个;剖面描述的基本发生层增加1个,特性发生层3个,等等。在此基础上分析提出了对中国土壤系统分类的几点建议:持之以恒开展研究、完善诊断层和诊断特性、继续人为土研究和加强组织建设等。

    Abstract:

    Comparison of the 9th edition of the Keys to Soil Taxonomy with the 8th edition of the Keys to Soil Taxonomy and the 2nd edition of the Soil Taxonomy: A Basic System of Soil Classification for Making and Interpreting Soil Surveys show that some amendments were made including revision of 4 Diagnostic Horizons and 2 Diagnostic Characteristics and addition of 4 Suborders, 12 Great Groups and 42 Subgroups to high levels of classification; 3 Strongly Contrasting Particle-Size Classes to displace one in diagnostic features of soil families and series; and 1 basic genetic horizon and 3 special genetic horizons. Based on the above generalization, some suggestions for Chinese Soil Taxonomy were put forward, such as continuing the research on soil classification to improve its Diagnostic Horizons and Characteristics, and the study on Anthrosols, and strengthening institutional construction, and so on.
