应用通径分析方法，研究了坡地赤红壤孔隙度、粉粒、粘粒、有机质等性质之间，以及坡地赤红壤的持水容量、粉粒、粘粒、有机质、孔隙度等性质之间的相互关系，探讨这些性质的相互作用对坡地赤红壤孔隙性和水分性能退化的影响，从而进一步探讨坡地赤红壤的物理退化机制。
The path analysis method was used to study the relationship between the properties of porosity, silt, clay, organic matter and the water holding capacity of red latosolic soil on the sloping land, and the properties of the silt, clay, organic matter and porosity The interaction of these properties on the porosity and water degradation of red soil in slopeland was discussed to further explore the mechanism of physical degradation of reddish soil in slopeland.
