摘　　要：潜水蒸发是干旱区天然植被耗水的主要来源,其大小决定着干旱区天然绿洲生态的规模。本文对干旱区潜水蒸发的影响因素和计算方法进行了系统地分析和讨论,以期为指导干旱区的生态建设提供参考。The phreatic evaporation is the main sources for the natural vegetation consumption of water, the evaporation capacity decides the size of inartificial oasis in arid region. The influence factor and calculation method for the phreatie evaporation were systematically analyzed and discussed, hope to provide the reference for guiding the ecology construction in arid area.
