In order to understand where North China paleo-latosol-like soils should be placed in Chinese Soil Taxonomy, study was carried out on soil properties and taxonomy of the Quaternary paleo-latosol-like soils in Chaoyang area of Liaoning Province. The soils were classified based on diagnostic horizons and diagnostic characteristics of the soils analyzed either by following the principle and methodology of the “Keys to the Chinese Soil Taxonomy (3rd edition)” with the soils deemed as parent material, or by proceeding from the soil genetic characteristics of the soils. Results show that the current version of the Keys to Chinese Soil Taxonomy (3rd edition) is unable to provide the paleo-latosol-like soils, a niche in the system. To solve the problem, the foremost task is to establish criteria for diagnosis of paleosols.
