摘要:
美国土壤系统分类中的Pale-类型是用于归类发育程度高、年龄大的土壤,在比较分析了两版《土壤系统分类》及各版《土壤系统分类检索》后,概括介绍了Pale-类型的设置缘起,及其检索条件和检索顺序的修订历程,在此基础上阐述了Pale-类型设置的演变历程对中国土壤系统分类的启示。

Evolution process of setting of Pale-Type in US soil Taxonomy

Abstract:
At the beginning of its development, the Chinese Soil Taxonomy referenced the US Soil taxonomy, citing no a few concepts and names therefrom. The comparison between the two systems found that in the latter existed a Pale-type, which was translated into a name that coincided with the name of a soil type in the former, but differed in connotation. The Pale-type in the US Soil Taxonomy encompasses great groups and subgroups of soils, and its detailed retrieval conditions show that it is a more specific category that has no similar soil type in the Chinese Soil Taxonomy. In the US Soil Taxonomy, Pale-type is used to classify soils high in development degree and old in age. Through comparing and analyzing two editions of the US Soil Taxonomy and several editions of the Keys to Soil Taxonomy, this paper briefly introduces the origin of the setting of Pale-type and the revision course of its retrieval condition and retrieval sequence. At present, many pedologists have proposed to revise the Chinese Soil Taxonomy. On such a basis this paper is going to expound how the evolution process of the Pale-type setting enlighted the development of the Chinese soil taxonomy, with a view to providing suggestions for revision of the Chinese Soil Taxonomy.
