| 摘 要： | 根据郑州市地下水均衡场1991～1996年地中渗透仪实测资料．分析了潜水蒸发与气象因素、埋深、土壤岩性及降雨入渗的关系。研究表明；潜水埋深较小(不大于1．0m)时，潜水蒸发与水面蒸发在动态分布上显示出极大的相关性；潜水蒸发随埋深增大急剧减弱；毛细上升高度和渗透性结合得比较好的土壤潜水蒸发较大；在埋深较小(不大于1．0m)时．单次集中降雨入渗对潜水蒸发影响显著。

| Abstract: | Based on the lysimeter data from the experimental station on ground water balance in Zhengzhou, the relationship between phreatic water evaporation and weather,water table depth, soil and precipitation recharge is analyzed. It shows that phreatic water evaporation relates closely to surface evaporation on dynamic distributing when the depth is no more than 1 meter, that phreatic water evaporation will become weakened with the descend of the water table depth, that reasonable capillary height and permeability will result in a higher value of unconfined evaporation and that precipitation recharge has a great influence on the process of phreatic water evaporation when the depth is no more than 1 meter. |
