References between the Genetic Soil Classification of China (GSCC) and the Chinese Soil Taxonomy (CST) for GSCC-Luvisols were conducted and their quantitative and spatial distribut ion characteristics within CST were studied, based on 1:1M Soil Database of China, which consists of 3 parts, 1:1M digital soil map, soils profiles attribution database and soil reference system of China.GSCC Luvisols are typical zonal soils with a total area of 1 059 757.8km², including 7 GSCC Groups, such as Dark Brown Soils (36.0%), Brown Soils (23.8%), Yellow Brown Soils (20.8%), Brown Coniferous Forest Soils (10.0%), Bleached Baijing Soils (4.3%), Yellow Cinnamon Soils (5.1%) and Bleached Podzolic Soils (0.01%), as well as 25 GSCC Subgroups.It can be sorted into 4 CST Orders, Argosols (72.8%), Cambosols (26.1%), Primosols (1.0%) and Spodosols (0.1%), and further into 25 CST Groups and 47 CST Subgroups, making the reference so complicated that there is almost no one to one reference relationship.Analysis of the area ratios and standard deviations of a certain GSCC soil classified by CST showed that the lower the unit for reference, the easier the reference would be.It is clear that Typic Dark Brown Soils can be sorted to Typic Bori-Udic Cambosols only, Bleached Yellow Brown Soils to Typic Ferri Udic Argosols, Bleached Brown Coniferous Forest Soils and Superfically Gleyed Brown Coniferous Forest Soils to Histic Permi Gelic Cambosoils, Yellow Cinnamon Like Soils to Typic Hapli-Udic Cambosols, Typic Bleached Podzolic Soils to Gelic Hapli Orthic Spodosols and Gleyed Dark Brown Soils to Gleyic Hapli-Boric Argosols.In order to make CST more practical and easier to popularize, it is essential and urgent to keep on studying and developing the CST at lower unit level to establish basic soil classification units of CST.The result of the study is of high reference value to proper reference between GSCC and CST and application and development of CST.
