摘要

扩散率是研究土壤水分运动必须的参数之一，其测定方法很多，该文采用非稳定流水平土柱法，对试验区扰动土壤的水分扩散率进行了测定，并将试验结果拟合为经验公式，应用于非饱和土壤水运动状态下预报水平入渗的土壤水分分布。

Abstract

Method of unsteady flow horizontal pillar is applied to determine soil moisture diffusivity of disturbed soil

which is one of the necessary parameters to study water motion in soil. The results are modeled into experience formulae which are applied to forecast soil moisture distribution of horizontally permeated flow in unsaturated soil water movement.
