分形理论在土壤科学研究中的应用

摘要

Soil system has the characteristics of nonlinear dynamic,which is known as one of the most complicated system.The fractal theory,as one of the newly arisen nonlinear science,has been used in the soil science for more than ten years.The application of the fractal theory on the soil science was introduced,including the application of fractal theory on the soil particle weight,surface area of soil,soil volume,soil water characteristic cure soil hydrodynamic transportation.%土壤系统具有高度的非线性和动态性特征,是已知的最为复杂的系统之一。分形理论作为一门新兴的非线性科学,应用于土壤学科已有十几年的历史。文章介绍了分形理论在土壤学的应用,包括分形理论在土壤颗粒重量、土壤颗粒表面积、土壤颗粒体积以及在土壤水分特征曲线、土壤水动力输运中的应用。
