Abstract
According to the characteristic data such as the number, size and shape of the macrospore through the digital image purchase and analysis technique, the pole fractal dimensions of the two different textures are calculated and compared by using the fractal theory.The predicting model of soil moisture characteristic curve and non-saturation hydraulic conductivity are obtained by using the macrospore fractal model.The results show that the pole fractal dimension Dv can describe the soil structure of the different textures, and the model based on it produces better results compared with those of the fractal model obtained from the particle size distribution estimation.
