| 摘 要： | 以祁连山针叶林树种青海云杉、油松、侧柏3种树种为研究材料,探讨了不同树种对祁连山森林灰褐土理化性质和水源涵养功能之间的关系。研究结果表明,土壤孔隙度、团粒结构、物理性黏粒含量均为青海云杉油松侧柏;土壤容重、物理性砂粒含量均为侧柏油松青海云杉;土壤有机质、CEC均为青海云杉油松侧柏;CaCO3含量、pH值、全盐含量均为侧柏油松青海云杉;土壤蓄水量和树种枯落物持水量均为青海云杉油松侧柏。

| Abstract: | The effects of tree species(Picea crassifolia,Pinus tabulaeformis,and Platycladus orientalis)on gray-brown soil properties and water conservation in Qilian Mountains are studied.Results show that by total soil porosity,soil granular-structure,and soil clay content,tree species are in the order of Picea crassifolia Pinus tabulaeformi Platycladus orientalis;by soil density and soil sand content,in the order of Picea crassifolia Pinus tabulaeformis Platycladus orientalis;by soil organic matter and CEC,in the order of Picea crassifolia Pinus tabulaeformis Platycladus orientalis;by CaCO_3,pH,and total soil salt,in the order of Picea crassifolia Pinus tabulaeformis Platycladus orientalis;and by soil water storage and litter holding capacity,in the order of Picea crassifolia Pinus tabulaeformis Platycladus orientalis. |
