[Objective] The aim of the study was to provide important reference value for afforesting Pinus massoniana plantations. [Method] In the Nanpan river valley margin area, 6,10,14 years-old Pinus massoniana plantation soil profile were selected, by the state standards the soil physical and chemical properties were determined. [Result]The results showed that: The soil bulk density of 0-100 cm soil layer were 0.997-1.606 g/cm~3; total porosity were 42.56%-61.03%; ventilation rate were 4.36%-39.45%. The pH value of 0-40 cm soil layer were 4.33-5.33, organic matter content were 9.02-49.99 g/kg, full N were 0.54-1.58 g/kg, full P were 0.35-0.86 g/kg, full K were 6.69-20.68g/kg. [Conclusion]The research demonstrated that the soil bulk density were larger,aeration were common, soil organic matter and N, P, K nutrient content were lower in Pinus massoniana plantations in dry-hot valley of the northwest of Guangxi.
