摘要/Abstract

摘要： 以长白山自然保护区内未受扰动的两种典型原始森林土壤为对象,通过野外选取原状土样,在实验室内测定其饱和渗透系数和有效孔隙度,利用回归分析法分别建立了森林土壤内饱和渗透系数和有效孔隙度随深度变化的数学模型,即K_s(z)=K₀-f₁lna₁z和ω(z)=ω₀-f₂lna₂z.将所得出的对数模型与Beven所提出的指数模型进行比较表明,在森林流域内对数模型不仅适用范围比指数模型广,而且精度明显高于指数模型,它更接近于野外实际情况。

Abstract: The saturated infiltration coefficient and effective porosity of two undisturbed soils taken from typical original forests in Changbai Mountain Natural Reserve were determined, and the mathematical models of them in different soil depth were established by regressive analysis, which are K_s(z)=K₀-f₁ lna₂z and ω(z)=ω₀-f₂ lna₂z .Acomparison of these logarithmic models with the Beven's exponential models shows that the formers are more accurate and more reasonable for forest catchment.
