The results show that pole fractal dimension Dv could describe soil structure of different texture and the model based on it produces better results compared with the fractal model obtained from the particle size distribution estimation.

• 结果表明,孔隙分形维数Dv可定量描述不同质地土壤结构,其模型预测精度优于颗粒大小分布估计的分形模型,可用于实际问题的研究之中。
