The quantitative characterization of the soil characteristics of calcareous plowed layer in the Loess Plateau by using the fractal dimension of soil particle size distribution was discussed.Based on the soil sample data of 24 calcareous plowed layers,the fractal dimension of soil particle in calcareous plowed layer in the Loess Plateau was studied by using the fractal model.The results showed that the fractal dimensions of the calcareous plowed layer soil ranged from 2.593 6 to 27 094.Fractal dimensions of ...
