Abstract: To study the attribution of genetic classification of paddy soil in Chinese Soil Taxonomy and explore the production ability of soil series, 7 typical profiles of paddy soil developed from granite in eastern Hunan Province were dug. The soil-forming environment and soil profile morphological characteristics were examined, and physicochemical properties were also analyzed. According to the Chinese soil taxonomy, under the suborder of stagnic anthrosol, 2 groups of fec-stagnic anthrosol and gen-stagnic anthrosol and 2 subgroups of typ-fec-stagnic anthrosol and typ-gen-stagnic anthrosol were identified. Six soil families and 7 soil series (Chexi series, Liujiachang series, Shuangjiachong serirs, Hongyang series, Baishu series, Wantou series and Fu’an series) were established. This study implied that quantitative indicators (particle size and texture profile) in Chinese Soil Taxonomy were more useful for soil basal classification than descriptive classification in genetic classification system.

Key words: anthrosol, diagnostic horizon, diagnostic characteristics, Chinese soil taxonomy, basal classification, agricultural production utilization
