摘　　要：对不同密度的4年生大叶相思林的土壤物理性质(容重、总孔隙度、毛管持水量、毛管孔隙度、非毛管孔隙度及自然含水量)进行了试验研究,结果表明:除中低密度大叶相思林非毛管孔隙度显著大于高密度的,以及高、中密度大叶相思自然含水量显著大于低密度的外,其他各物理性质之间差异不显著。由此可见,三种密度大叶相思林的物理性质相近。期望研究为合理管理大叶相思人工林提供理论依据。The soil physical properties（soil density,total porosity,capillary moisture content,capillary porosity,non-capillary porosity and natural soil water content）was studied in Acacia auriculaeformisstands with different densities to provide theory basis for rational management of Acacia auriculaeformis stands.The results showed that there is no significant difference between the soil physical properties except for non-capillary and natural soil water content.Generally the differences in soil physical properties of the three density stands were small.
