| Abstract: | Seven typical soil profiles of cinnamon soil in Central and Western in Henan Province were selected as study objects to determine the attribution of 7 soil profiles in Chinese Soil Taxonomy(CST) by comparing their physical properties and chemical properties. With reference to “Chinese Soil Taxonomy(3 rd edition)”,the studied soil profiles were found to have the following diagnostic horizons and characteristics: Argic horizon,Calcichorizon,cambichorizon,Calcicevidence,Redoxfeatures,Calcaricproperty,Ustic soil moisture regime,Udic soil moisture regime,Aquic soil moisture regime,Mesic soil temperature regime,Thermic soil temperature regime. Of the 7 soil profiles,4 soil profiles were classified into Argosols and 3 soil profiles were classified into Cambosols. With reference to “Criteria for Establishment of Soil Family and Soil Series in Chinese Soil Taxonomy”,7 soil series like Yangling soil series and Zhuge soil series were established. And the reference between the Chinese Soil Genetic Classification and the Chinese Soil Taxonomy was made from higher taxon level and basic higher taxon level respectively. In addition,the reference study among CSGC,CST,WRB and ST was carried out at the higher taxon level. It is also suggested that the Group of “ CalciUstic Cambosols ” should be added to the CST. |
