Relationship between spatial variability of soil water content, soil electrical conductivity, sand content, clay content, slit content, fractal dimension of soil particle-size distribution, bulk density and organic matter content in 0~20cm soil layer and their spatial variabilty in 20~40cm soil layer at multiple scale was studied with joint multifractal. The results showed that changing ration for spatial variability of slit content and organic matter content was the largest, the one for spatial variability of soil electrical conductivity, clay content and fractal dimension of soil particle-size distribution was the least, and the one for spatial variability of sand content, soil water content and bulk density lay between the two in 20~40cm soil layer compared with spatial variability of corresponding variables in 0~20cm soil layer; at multiple scale, relationship between spatial variability of soil water content, bulk density, organic matter content, clay content, sand content, soil electrical conductivity, fractal dimension of soil particle size distribution and slit content in 0~20cm soil layer and corresponding soil properties in 20~40cm soil layer decreased gradually.
