The Characteristics of Ferralosols References between Chinese Soil Taxonomy and Genetic Soil Classification of China

References between Genetic Soil Classification of China (GSCC) and Chinese Soil Taxonomy (CST), characteristics of distribution of GSCC-Ferralosols in CST were studied, based on 1:100M Soil Database of China. GSCC-Ferralosol is a type of zonal soil with a total area of 1,122,969.6 km2 in China. There are 6 CST Orders referenced with GSCC-Ferralosols, including 25 CST Groups and 53 CST Subgroups, such as Ferrosols, Argosols, Cambosols, Ferralosols, Primosols and Vertosols, in percentages of total area of GSCC-Ferralosols respectively 34.8, 32.2, 26.1, 6.3, 0.6 and 0.04. The reference relationship between GSCC and CST was so complicated that there were no obvious distribution rules for the GSCC-Ferralosols in CST. Results obtained from statistics of references area of the soils in CST show that it is easier to grasp references if the references are all at lower level for both GSCC and CST. Although CST has been finished at high level, it is important and urgent to study and develop the CST at basic level, in order that the CST can be widely used. The result is also useful for soil reference and application of CST.
