Two hundred and thirty-seven soil profiles from Hainan Island were identified and classified according to Keys to Chinese Soil Taxonomy (3rd edition). The placement of 28 taxa, formerly sorted on subgroup level of Chinese Soil Genetic Classification System, in Chinese Soil Taxonomy was elucidated in the paper. The taxonomic soil classification of Hainan Island was proposed. And the correlation of taxa between Chinese Soil Genetic Classificafion (CSGC) and Chinese Soil Taxonomy (CST) was also discussed.
