摘　　要：对地处南亚热带的广西高峰林场林业示范基地不同林龄的尾巨桉林、灰木莲林和厚荚相思林3种人工林林地0～40 cm土层土壤的理化性质进行了研究。结果表明,3种人工林林地的土壤较为疏松,持水性能较强;土壤养分含量除磷元素相对偏低外,其他元素的含量较为丰富。其林地土壤的养分含量及物理性状优良度的排序为:灰木莲林>厚荚相思林>尾巨桉林。方差分析结果表明,3种林分林地土壤除pH值差异显著外,其他指标的差异不显著。In the forestry demonstration base of Gaofeng forest farm,three forest plantations including Eucalyptus urophylla×E.grandis,Manglietia glauca and Acacia crassicarpa at different ages were selected to measure soil physical and chemical properties（0~40 cm）.The results showed that the soil of three forest plantations in the demonstrative area is loose with strong water holding capacity,the soil nutrient contents were relatively rich except phosphorus element.The soil nutrient contents and physical properties were in order as follows ：Manglietia glauca 〉Acacia crassicarpa 〉Eucalyptus urophylla×E.grandis.The variance analysis showed that the indexes except pH value had no significant difference.
