摘　　要：基于阿尔乡沙地潜水蒸发试验场2010年4月中旬～10月上旬的实测资料,分析了裸地条件下沙地潜水蒸发的影响因素及其相关规律。试验结果表明,潜水蒸发与水面蒸发的变化趋势一致,降雨对潜水蒸发和入渗补给过程的影响大于蒸发对其的影响;地下水埋深对潜水蒸发的影响主要集中于0.0～1.0m之间;地下水埋深1.5m处,入渗补给量达到最大值;沙地的潜水零补耗差深度在0.5～1.0m之间,最佳潜水埋深为1.5m。Based on the date obtained from the experiment station of phreatic water evaporation on sandy land in A＇erxiang Town,which is from mid April to early October 2010,the influence factors and its variation rules of sandy phreatic water evaporation at condition of bare land is analyzed.The results show that the variation trend of phreatic water evaporation is in accord with water surface evaporation;the main factor which influences the whole process of phreatic water evaporation and infiltration recharge is rainfall;at the depth interval of 0.0 to 1.0 m,the effect of groundwater buried depth on phreatic water evaporation is great;the infiltration recharge reaches maximum when the groundwater buried depth is 1.5 m;the critical depth of phreatic water balance in unsaturated-saturated system on sandy land is between 0.5 and 1.0 m and the best buried depth of phreatic water is 1.5 m.
