In this paper, the soil characteristics of three different afforestation tree species were studied by selecting the representative standard of three different afforestation species in Jiepai,Gaofeng forest farm of Guangxi..Results showed thatthe physical properties of the soil are poor, and Pinus massoniana and Cunninghamia lanceolata are ideal economic tree species and timber species.The soil physical and fertility conditions are both good, withmoderate hardness, good ventilation and good water permeability.%选择3种不同造林树种的代表性标准地,对广西高峰林场界牌分场3种不同造林树种人工林下的土壤特征进行研究.结果表明:巨尾桉林分下土壤的物理性质较差,而马尾松与杉木是理想的经济林树种和用材树种,其林分中土壤物理和肥力状况都不错,软硬适中,通气透水性好.
