| 摘 要： | 根据辽宁省阜新市阿尔乡沙地潜水蒸发试验场2010年4月中旬至10月上旬（非冻结期）的实测资料,分析了有作物条件下辽西北沙地潜水蒸发的影响因素及其相关规律。研究表明,有作物时潜水蒸发与裸地不同,它不仅与大气蒸发能力、地下水埋深和土壤性状有关,还与作物的生育阶段有关;入渗补给量随着地下水埋深的增大而减小;潜水补耗差随地下水埋深的增大呈现出先减小后增大的趋势。确定0~2.0 m埋深区段为辽西北沙地种植柠条的不适宜潜水埋深区。

| Abstract: | This article mainly analyzed the affecting factors and related laws of phreatic evaporation under crop growing on sandy land in Northwest Liaoning based on the data obtained from the experiment station of phreatic evapolation on sandy land in A'er village,Fuxin City,Liaoning Province from the middle ten day-period of Apr.to the first ten-day period of Oct.2010.The results show that there is difference between the lows of phreatic evaporation and bare land.It is not only related to evaporation capacity of at... |
