| Abstract: | A spatial variability structure of the environmental background values for element calcium of the topsoil in China was analysed. Based on this, the localized optimal estimation of the environmental background values for element calcium was made. The results showed that this estimation method highlighted a macroscopic variability regularity of the environmental background value for element calcium of topsoil in China. Compared with trend surface analysis method, it has obvious advantages. |
