- Abstract:
- Soil particle size distribution is the result of interactions between soils and their environmental factors, so it can reflect certain properties of environmental factors. Aimed at analyzing the characteristics of particle size distribution of the soil under different water-erosion degrees in southern China, the fractal dimension of the soil particle size distribution was calculted, and the relationships between the fractal dimension values and soil textures or soil erosion degrees was explored. The results showed that, the gravelly soil dominated the soil textures in the study area. The volume and weight fractal dimension values of the soil particles less than 2 mm were between 2.52 to 2.99 and 2.48 to 2.73, respectively. The accumulated percentage of weight changed significantly at the soil particle size of 2 mm, and the weight fractal dimension values were 1.79~2.81 and 2.52~2.79 for the soil particle size greater than 2 mm and lower than 2 mm, respectively. The weight fractal dimension values for the soil particle size greater than 2 mm were significantly related to both soil textures and soil erosion degrees. The finer the soil texture or the less severely the soil eroded, the greater the weight fractal dimension for the soil particle size which is greater than 2 mm, and vice versa. Therefore, the weight fractal dimension for the soil particle greater than 2 mm can indicate the soil texture and soil erosion degree in the study area.
