Title: Influence of Agricultural Non-point Source Pollution on Fractal Dimensions Feature of Soil Particles
Abstract: The fractal dimension feature of soil particles under different utilization patterns was analyzed to study the effect of agricultural non-point source pollution on soil character.The results showed that the fractal dimension of soil particles was between 2.891 and 2.949,there was a significant positive correlation between soil fractal dimension and soil clay content,and the content of organic matter and total nitrogen in soil increased with the increase of the fractal dimension.The performance of soil fractal dimension feature under different land utilization patterns was tea gardenupland landpaddy fieldvegetable field and the soil fractal dimension of the single cropping model was higher than that of the double cropping model.The soil fractal dimension decreased with distance increase from settlements.The greater the soil fractal dimension is,the more the soil clay content has,the stronger nutrient adsorption capacity the soil has.The fractal dimension of the soil particles may be an important index reflecting the development trend of soil desertification in the process of agricultural non-point source pollution.
