Soil has the fractal characteristic. Soil fractal dimension (SFD) can be used as an important index of soil. In this study,30 soil samples from 7 soil types and 4 landuses were collected. Soil particle-size distribution,soil bulk density,saturated water content,saturated hydraulic conductivity,and soil organic matter were measured. The SFD was then calculated according to soil particle-size distribution. Results showed that the fractal dimension in Beijing region had a low variation coefficient. Significantly positive correlative relationships between the SFD and clay content and between the SFD and saturated hydraulic conductivity were found. The fractal dimension was negatively correlated with the ratio of (sand content + silt content)/clay content. The SFD can be a potential parameter to reflect soil texture,but is not a rational indicator to reflect soil physical properties under complex geographical environment.
