| Abstract: | Geostatistic method combined with GIS was applied to analyze the spatial variability of soil organic matter in Yuzhong County in Gansu Province as example.The result indicated the spatial heterogeneity degrees were moderately dependent,and the semi-variograms of soil organic matter is best fitted by spherical model.The distribution pattern of soil organic matters in Yuzhong County displayed higher in the middle and west part,but lower in the north and east part. |
