| Summary: | Spatial pattern characteristics of different soil types and regularity of soil type distribution are of great significance for the sustainable use of regional soil resources. Based on geomorphological factors, the typical transects in Hebei Province was divided into four ecological regions. The spatial distribution of soil types over these four ecological regions was analyzed quantitatively using a geographic information system (GIS) and by applying the principles of landscape ecology. The dissociation index of soil types in the four ecological regions were within a range 0~5, indicating clustered distribution. The soil types of the central plain area showed a high degree of landscape isolation, whereas soils of the littoral plain area showed a low degree of landscape isolation. Soil type in the Taihang Mountain area and in the piedmont plain area were more complex, soil type diversity in the littoral plains area was less complex, and soil type complexity was the lowest in the central plains area. Soil type richness in the Taihang Mountain area was the highest, indicating high heterogeneity within this area. The spatial pattern of soil types in the littoral plain area showed a low degree of fragmentation. The spatial soil pattern in the central plain area was dominated by several soil types covering extensive areas, whereas the piedmont plain area was dominated by multiple soil types. This study provides a useful reference for the sustainable use and protection of soil resources. |
