摘　　要：阐述了森林流域几种土壤水分运动方式(入渗、潜水蒸发、潜水补给以及壤中流)中非饱和土壤水与饱和土壤水之间转化的研究进展,并对土壤水分运动参数中的土壤水分特征曲线、非饱和导水率和饱和导水率的研究现状作以简要介绍,最后提出了未来的发展方向.This paper reviewed the studies on the movement ways, i. e., infiltration, phreatic evaporation, ground water recharge and interflow, of unsaturated and saturated soil water in forest catchments, and introduced the present advances in soil hydraulic parameters, including soil water characteristic curve, and unsaturated and saturated soil hydraulic conductivity. Research directions in the future were also proposed.
