The micromorphological fractal features of cultivated soil in the Northern Weihe area are studied using fractal geometry method. With the aid of polarizing microscope and SISC IA S V8. 0 softw are, micromorphological features of the cultivated soils are observed. Void and coarse grain features and the fractal d-imensio n of the cultivated soils are analyzed and calculated using the box-co unting method. Results show that void fractal dimensio n has a good relativity w ith porosity, void area, and void perimeter, w ith the correlatio ncoefficients being 0. 77874, 0. 68558, and 0. 81487, respectively. Coarse grain fractal dimensio n takes on a good relativity with are a ratio, coarse grain area, and coarse grain perimeter, with the correlation coefficients being 0. 984 18, 0. 984 06, and 0.93010, respectively. The fractal dimensions of soil micromorphology are able to indicate the distribution characteristics of soil structure and the influences of human cultivation.
