Properties of fractal dimensions of albic soil for radix ginseng culture

The method for calculating the factal dimensions of soil particle surface was used to study properties of fractal dimensions of albic soil for radix ginseng culture in Jilin Province. The results indicated fractal dimensions of soil particle surface were 2.890～2.963 and increased with the increase of soil viscosity. Statistic analysis indicated that fractal dimensions were in the partial correlation with bulk density, pore space, content of on-available water, and larger than 0.25 mm aggregates(coefficients are 0.747, 0.796, 0.798 and 0.826). Fractal dimensions may be used to judge physical fertility of albic soil for radix ginseng culture.
