| 摘 要： | 通过对湘西南山地21块典型植物群落标准地的土壤渗透性能研究表明,不同标准地的贮水能力受土壤的厚度和非毛管孔隙度的影响较大,在264.0-912.0 t/hm^2之间;土壤的初渗速度在17.75-35.42 mm/min之间;土壤的稳渗速度在4.31-11.34 mm/min之间;土壤入渗过程的回归方程表现为乘幂函数形式,回归系数R在0.88~0.97之间,方程拟合效果较好。

| Abstract: | Researches of the soil permeability at 21 sample plots in mountains areas of south west H unan indicated that water storage capacity of different sample plots was influenced by soil thickness and soil non-capillary porosity,and its values are between 264.0-912.0 t/hm^2. Soil initial permeability coefficients are between 17.75-35.42 mm/min,and solid permeability co- efficients are between 4.31-11.34 mm/min. Soil permeability coefficients regression equation performs exponent relation. Regression coefficients are between 0.88-0.97,and it shows that equation analog effect is good. |
