摘　　要：本文从不同尺度(区域、类型及单个土体)对我国土壤发生分类与系统分类进行参比。区域参比是以某一土区内主要土壤类型中心概念推知的诊断层和/或诊断特性为根据;类型参比是以某一土壤类型中代表性剖面具有的诊断层和/或诊断特性为根据;单个土体参比则是以某一单个土体具有的诊断层和/诊断特性为根据。根据掌握资料数据的实际情况,选用不同尺度的参比能够更简易地、更可靠地确定发生分类类型在系统分类中的归属,为广泛应用系统分类提供方便。Correlation of soil taxa between Chinese soil genetic classification and Chinese soil taxonomy on various scales (i.e. region, category and pedon) is discussed in the paper. The 揜egion reference?is based on the diagnostic horizons and/or diagnostic characteristics inferred from soil genetic conception of predominant soil taxa in a region; the 揅ategory reference?is based on the diagnostic horizons and/or diagnostic characteristics of a representative profile of a taxon; and the 揚edon reference?is based on diagnostic horizons and/or diagnostic characteristics of a pedon. Niches of taxa of the Chinese soil genetic classification can be more feasibly and reliably defined in the Chinese soil taxonomy by applying the reference of soil taxa on various scales according to the actual situation of soil data available, thus making it more convenient to extensively use the Chinese soil taxonomy.
