摘要: 介绍国内外林地土壤水分入渗模型、林地土壤水分运动方程、森林流域壤中流模型及其验证和应用,并
对这些模型做对比分析,指出各自的优点和不足,阐述深入研究林地土壤水分运动的重要意义。同时,说明今后该
领域的研究应结合退耕还林工程中的实际科学问题,针对森林土壤水分研究中的薄弱环节,探索变雨强、变容重和
大面积流域的林地土壤水分动力学规律,从而使森林土壤水分的研究走向成熟和系统化的阶段,为森林流域水资
源的合理利用和水分循环的计算提供科学依据。

Abstract : In this paper , infiltration model , formula of soil water movement and interflow in forestland were introduced and
analyzed contrastively , and the advantages and ings were pointed out. Meanwhile , the significance of research on soil
water movement in forestland was stated that would help for the calculation of water cycle and the reasonable utility of water
resources. The prospective tasks of this field were directed clearly , which is to study the laws of water movement in forestland
based on the changing rainfall intensity , changeable bulk density and big basin.
Key words : soil water in
