| 摘 要： | 利用分形几何理论，可在水分特征曲线与土壤结构分维之间建立一定的函数关系式。利用这些函数关系式与Campbell经验公式具有相同或相似的幂定律形式的特点，由土壤水分特征曲线反推土壤孔隙分形维数，这不仅可以揭示Campbell经验公式与土壤孔隙结构之间的内在联系，还可为建立土壤非饱和水力参数的分形模型提供理论依据。

| Abstract: | Functional equations can be established between the soil water retention curve and the fractal dimension of soil structures by the fractal geometry theory. Based on the property of the same or similar power-law between both the functional equations and Campbell law, an inverse deduction on the fractal dimension of soil pore is made with the soil water retention curve; from which not only the inner relationship between Campbell law and the structure of soil pore can be revealed, but a theoretical basis for the fractal model of the unsaturated soil hydraulic parameters can also be estasblishied. |
