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 “Region reference” is based on the diagnostic horizons and/or diagnostic characteristics inferred from soil genetic conception of predominant soil taxa in a region; the “Category reference” is based on the diagnostic horizons and/or diagnostic characteristics of a representative profile of a taxon; and the “Pedon 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.
