Soil property spatial distribution map is one of direct expressions of soil spatial variability. The traditional soil property maps, which wre made by the surveyors using their intuition and formal knowledge and understanding to collate all the information available on the soil, were difficult to quantificationally reflect the distributions of soil properties. This paper mainly discussed how to apply GIS to create quantitative soil property spatial distribution maps with an example by ArcInfo7.1.
