土壤大孔隙流研究中分形几何的应用进展

Fractal geometry application to the study of macropore flow in soil

土壤中普遍存在的大孔隙使水及溶质快速穿过土壤 ,污染地下水 ,确定土壤大孔隙流性质需要大量的野外和室内实验。本文在对分形几何概念进行简要阐述的基础上 ,介绍了分形几何在土壤大孔隙流研究中所取得的成果 ,结果表明应用分形几何确定土壤大孔隙流性质是一种省时、省力和具有广泛代表性的方法 ,最后对分形几何在土壤大孔隙流研究中应用前景作了展望。

Water and solutes go fast through the macropores in soil and pollute groundwater.Field and laboratory tests are needed to determine the macropore flow properties.Some fractal geometry concepts applications to the study of macropore flow are introduced in this paper.It is shown that fractal geometry is a good method to estimate macropore flow properties with high effiency and low manpower.The method is finally prospected by the paper.
