【 摘 要 】

Taking purple soil from Mouding city as the research object, the aim of this paper is to discuss the number characteristics of dryland soil aggregates. The results indicated that cumulative amounts of dryland soil aggregate obtaining from artificial screening method were obeyed the log-linear distribution, and fractal dimension of soil was ranged from 2.11 to 2.48. Moreover, the higher aggregates content was contained, the larger aggregates fractal dimension in the soil particles, which was smaller than 0.25 mm. The fractal dimension of dryland aggregates was decreased with the increasing of soil depth.
