To fully explore the reason of finger flow and its change law,taking three kinds of soil,which is wildly distributed in northwest of China,as experiment material,the finger flow experiment of layered soil and homogeneous soil under the condition of sufficient water supply indoor is conducted in this paper.
为了彻底认识指流的发生原因及变化规律,以我国西北地区分布较为广泛的3种土壤(西峰土、榆林土、新疆沙土)为实验对象,对均质土壤和层状土壤进行室内充分供水条件下的指流实验,发现层状土壤均有指流产生,而均质土壤则没有指流发生,并对其原因进行了简要分析。
The spatial distributions of soil hydraulic properties and soil water Variables in a stratified soil are described as random space functions,and three types of models of AR(1),MVAR (1),and NNM are adopted to generate realizations for saturated hydraulic conductivity, poresize distribution parameter and soilwater capacity.
在田块尺度条件下的层状土壤中，土壤水力特性及土壤水分变量在空间上的分布可以看作是一维随机空间函数的实现。
