土壤碳储量计算中不同插值方法对比研究——以吉林省大安市为例
Contrastive studies on different interpolation methods in soil carbon storage calculation in Da'an City, Jilin Province
摘要
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 equationmodel of original Kringing achieves the highest accuracy.关键词
