摘要:
通过对女儿寨森林小流域11块标准地土壤渗透性能的研究表明,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112~598.5 t/hm2之间;土壤的初渗速度在18.62~38.94 mm/min之间;土壤的稳渗速度在1.42~7.61 mm/min之间;次生林比人工林具有更强的渗透性能;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0.88~0.99之间,方程拟合效果较好.
Abstract:
By research of the soil permeability of 11 sample plots at NÜerzhai small area watershed,it is proposed that water storage capacity of different sample plots is influenced by the thickness of soil and soil non-capillary porosity,and its values are between 112~598.5t/hm2.Soil first permeability coefficients are between 18.62~38.94 mm/min,and solid permeability coefficients are between 1.42~7.61mm/min.Secodary natural forest has better permeability than plantation.Soil permeability coefficients regression equation performs exponent relation.Regression coefficients are between 0.88~0.99,and it shows that equation analog effect is good.
