通径分析在赤红壤物理退化机理研究中的应用

Application of Path Analysis to the Studies of Possible Mechanism of Physical Properties Degradation of Latored Soils in Slope Land

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。

Using the path analysis method, this paper deals with the correlation among the physical and chemical properties of porosity, silt, clay, organic matter water-stable aggregates; and of water holding capasity, silt, clay, organic matter,>0.05mm and <0.05mm pores of latored soils. By analyzing the effects of the interaction among the above factors, the possible mechanism of physical properties degradation of latored soils on slope land is studied further.
