Abstract
The fractal geometry to the study of soil structure, its dynamics, and physical processes appears to be a useful tool in reaching a better understanding of system performance. This research was designed to apply fractal models for mass into computingD p andD a values. As a result, the relationships among land use methods, fractal dimension and soil fertility have been discussed. The study conclusions include that (i) fractal dimension indicates not only characteristics of soil texture but also effects of natural environment changes and human activities on soil properties, (ii) soil fertility is best whenD p<2.65 andD a<2.44, (iii) maximal values ofD p under all land use patterns are equal and appear in the range the depth of 15–20 cm in the study area, but maximal values ofD a are different and distribute in various profile depth. These results can provide an important support to understand soil properties in plateau soil-forming environment, and be helpful to conduct scientific soil tillage and management.
