%X 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.
