    Abstract
  • Soil carbon storage is the focus in the studies on greenhouse effect and global change. Total organic carbon storage and average organic carbon storage in surface soil are calculated by means of Unit Soil Carbon Storage in this study. Different interpolation models such as Inverse Distance Weighted, Global Polynomial Interpolation, Local Polynomial Interpolation, Radial Basis Function and Kringing are analyzed and compared. The interpolation results show that mean error, average absolute error and root mean standard error are the minimum when using the GPI, the RBF and the Kringing models respectively. The quadratic equation model of original Kringing achieves the highest accuracy.
