Soil mapping based on quantitative soil-landscape model has been studied all over the world. This paper chose a hilly area in Xuancheng, southern part of Anhui province, as the study site, and produced soil mapping based on quantitative soil-landscape models relying on quantitative relationships between soil and landscapes. The results showed that there were strong correlations between solum thickness, organic material content in topsoil and some of topographic indexes. Quantitative soil-landscape models could explain 32.2% and 35.3% of the spatial variations of solum thickness and organic content in topsoil, respectively. The predicted values of solum thickness and organic content in topsoil on validation points by the two soil-landscape models matched the determined in a high degree. Additionally, the maps produced by the two soil-landscape models kept the natural spatial continuity of soil properties, which cannot be captured on traditional soil maps.
