| 摘 要： | 从土壤物理性质、蓄水量、贮水量等角度对祁连山苔藓云杉林、祁连圆柏林、亚高山灌丛林、牧坡草地4种主要植被类型的土壤渗透功能进行分析,结果表明土壤的渗透功能主要由土壤非毛管孔隙度的质和量决定的,苔藓云杉林土壤非毛管孔隙度的质和量最好,它的渗透功能也最好;虽然亚高山灌丛林的渗透功能次之,但由于它自身的特点,蓄水性能最好,又加之面最大,因此,贮水量也最大.

| Abstract: | Four main vegetation types, which are Picea crassifolia,Sabina przewalskii,bushes and pastureland ,whose soil permeability function was analyzed from angle of its physics,capacity of water, storing water in it .Results as follow: permeability function of soil is controlled by puaality of soil hole.The puality of soil hole of Picea crassifolia is the best ,of which permeability too. Permeability of bush soil is the second ,but because of its characteristics, the ability of what storing water is the best ,and its area was the most,so their storing water in soil is the most in Water Resource Conservation Forest in Qilian Mountains. |
