| 摘 要： | 从定性和定量两个层面分析了潜水浅埋深条件下季节性冻融土壤水分运动的一般规律,结果表明：1）冻结期内土壤水分向上运动,潜水补给土壤水;消融期则以20～40cm深度为界,土壤水分向上下两端运动,土壤水补给潜水,整个过程导致潜水位先降后升,但一部分损失于潜水蒸发.2）在冻融过程中各个阶段,20～40cm以上土层和以下土层水分...

| Abstract: | Water movement regularities of seasonal freezing-thawing soil in shallow groundwater were analyzed by both quality and quantity approaches.The results show that: 1) in freezing period,soil water moved upwards,groundwater also supplied to soil water;in thawing period,soil water moved two sides from depth of 20-40 cm,and supplied to groundwater downwards,the whole process led the depth of groundwater down and up,but some lost in groundwater evaporation.2) In every period,soil water above and below 20-40 cm sh... |
