简要介绍了利用土壤剖面二值图像分析土壤孔隙结构质量分形维数Dm的方法，并对4种土壤的Dm值及其影响因素进行了研究。结果表明，Dm可以定量描述孔隙结构的空间分布特征。Dm随孔隙面积的增大而增大，随大孔隙和土层深度的增大而减小。然而，细质地的土壤一般具有较小的Dm相比，粗质地的土壤。
This paper introduced briefly a method to analyze the mass fractal dimension Dm of pore structure in soil by using the binary images of soil sections, and studied Dm of four types of soils as well as the factors influencing Dm . The results showed the potential of Dm to describe quantitatively the spatial distribution characteristics of pore structure. Generally, Dm increased with the increases of pore area, while decreased with the increase of large pores and soil depth. However,the soils with fine texture generally had a smaller Dm compared with the soil having coarse texture.
