基于多重分形的土壤粒径分布与土壤物理特性关系
Relationships between Soil Particle Size Distribution and Soil Physical Properties Based on Multifractal
摘要
Abstract
In order to describe the relationship between soil particle size distribution and soil physical properties, the parameters of soil particle size distribution, soil bulk density and soil saturated hydraulic conductivity were measured, and the heterogeneity of soil particle size distribution was characterized by the parameters of multifractal spectrum, and then the relationship between multifractal parameters of soil particle size distribution and soil bulk density, soil saturated hydraulic conductivity were discussed. The results showed that the heterogeneity of soil particle size distribution could be reflected by the multifractal parameters of soil particle size distribution such as D1/D0 and △α, the multifractal parameters were closely related with soil clay content, and when the soil heterogeneity is larger, the soil clay content is higher, and that results in soil bulk density increasing, soil saturated hydraulic conductivity decreasing. Therefore, the multifractal parameters of soil parameters can be used as an indicator to reflect the soil physical properties.关键词
