摘　　要：通过室内土柱试验,研究了50、70、90cm地下水埋深的土壤盐分运动对土壤蒸发的影响。结果表明:1不同地下水埋深条件下,土壤水分运移有一定差异,地下水埋深越浅,土壤水分越高;2时间上,随着蒸发的进行,阶段平均蒸发量逐渐从依次为5.8、5.6、5.6mm/d减小到3.5、2.6、2.2mm/d。随着地下水埋深的增加,蒸发速率和蒸发量均减小。Laboratory soil column evaporation experiments were conducted to study the influences of soil salt movement on soil evaporation under different groundwater depths of 50 cm, 70 cm, and 90 cm, respectively. The results showed that： ①the differences existed under different groundwater depths, and the shallower groundwater depth, the higher soil moisture content. ②With the evaporation time, average evaporation rates were reduced from 5.8 mm/d, 5.6 mm/d, 5.6 mm/d to 3.5 ram/d, 2.6 ram/d, 2.2 mm/d, respectively. With the increase of groundwater depth, both evaporation rate and soil evaporation decreased.
