| 摘 要： | 研究了八角林地土壤水分-物理特性,并与相似立地条件、相近林龄且均为成熟林的马尾松林和灰木莲林进行比较.结果表明,与马尾松林相比,八角林、灰木莲林的表层土壤(0～20cm)和下层土壤(20～40 cm)的水稳性团聚体、非毛管孔隙度、毛度孔隙度、自然含水量、最大持水量、田间持水量和渗透性能均呈增大趋势,土壤结构破坏率和容重则呈减小趋势.八角林具有改良土壤结构和水分性能,有利于林地地力的维持和林业的持续发展.

| Abstract: | The changes of soil moisture physical characteristics in plantations of Illicium verum, Pinus massoniana and Manglietra glacua with similar conditions and similar tree age(mature plantation) were studied. The results indicated that compared to P. massoniana plantation, soil water-stable aggregate, nin-capillary pore, capillary pore, moisture capacity, maximum moisture capacity, permeation capacity and main nutrients in I. verum and P. massoniana plantations at topsoil and subsoil increase, whereas the rate of structure fragmentation and volume of soil decrease. It concluded that I. verum and M. glacua plantations had a good ability to improve soil structure and moisture condition and advantageous to the sustainable development of forestry. |
