The results showed that the sandy soil in layered soil profile can stimulate or obstacle the water movement as compared to the uniform loam column with 50cm depth of water table, this was mainly determined by the position of the sand layer.

结果表明，砂层对于水分的蒸发既有促进也有抑制作用，在地下水埋深为50 cm时，5 cm厚的底砂层可使水分的蒸发强度增加10%～20%；砂层距水位的距离大于5 cm时，砂层可抑制水分的蒸发，且当距离增加到35 cm左右，其抑制率可达70%～80%；当砂层距水位的距离继续增大时，水分的蒸发强度基本保持不变。
