- Abstract:
- How to use limited soil samplings to predicate an accurate spatial distribution of soil properties is always a hot issue. Method of using land use and Kriging to indicate soil organic carbon spatial distribution was explored by variance analysis with the data of Hebei Province of the Second National Soil Survey. The results showed that land use was a factor impacting soil organic carbon spatial variation and could be used to reflect the spatial distribution of soil organic carbon. But the independent reflecting ability of land use to variation of SOC density in the surface was not very high, land use and ordinary Kriging interpolation in combination could significantly increase explanatory strength of SOC spatial variation. Therefore, Kriging interpolation could be combined with land use to indicate the spatial distribution of regional soil organic carbon in the topsoil.
