Title: Spatial Heterogeneity of Soil Properties and Their Affecting Factors in the Northern Jiangsu Province
Abstract: The research on spatial heterogeneity of soil properties is considered to be an important topic in utilizing and managing soil resources properly. Based on a 1 ∶50 000 soil database, spatial heterogeneity of surface soil (0-20cm) properties (including soil texture, pH, organic matter and CEC) and their affecting factors in the northern Jiangsu Province was analyzed. The results showed that soil pH in the study area was basically higher than 7.0. Spatial distributions of soil organic matter and CEC were similar, which showed that both values in Huai'an were significant higher than those in the other areas. Soil properties were significantly affected by soil type and parent material. In terms of soil group, bog soils had the highest clay content, organic matter and CEC. With regard to parent material, soil organic matter and CEC were higher in soils developed from lacustrine deposit than those from other parent materials. It was concluded that soil type was the dominant factor for the spatial heterogeneity of clay content, organic matter and CEC, while parent material was a key factor for soil pH at the scale of 1∶50 000.
