Abstract: Regular square grids with 2 m spacing was adopted to study the spatial variability of the cinnamon soil mechanical composition in a 10 m×20 m plot. The statistics eigenvalue of the samples show there was the high spatial variability in the cultivated soil layer. The regularity of the spatial variability can not be clarified by the normal Kriging due to the sampling data does not submit to the hypothesis of the normal or logarithm normal distribution. The overlapping moving window was applied to take effect from the highly variability data, and then, the estimated values of the standardized rank space were obtained after the spatial structure of standardized rank assessed by the rank-order geostatistics. The estimated standardized rank was back-transformed into the sampled space by the middle point model within a standardized-rank interval, and the spatial distribution regularity in zonal anisotropy was clearly regularized for the cinnamon soil mechanical composition.
