Abstract: This study aims at the universal understanding of soil formation and taxonomic classification in subtropical mountains. It is useful for promoting pedogenesis research progress and orogenic soil series establishment in midwest China, and is further essential for sustainable utilization of orogenic soils. The edaphogenic characteristics and taxonomic classification of orogenic soils in subtropics of China were reviewed, including characteristics of major geochemical and soil- forming processes, principal diagnostic horizons, characteristics and phenomena, the altitudinal distribution of senior taxon, and diagnostic criteria of basic taxon. Then, several research priorities were proposed for the orogenic soil taxonomy in subtropics of China: (1) deeply understanding the geochemical and soil- forming processes; (2) establishing typical soil families and series, and testing the current criteria of basic taxon in subtropics of China; (3) strengthening the standardization of indices and data; (4) applying micromorphology, modern instrumental analysis and database technologies.
