| 摘 要： | 以松嫩平原西部典型苏打盐渍土区为研究对象,以野外定位试验和室内模拟分析相结合,借助于分层土壤水分平衡模型,探讨苏打盐渍土壤水分运移的基本特征和规律,并分析其与浅层地下水之间的交换关系。研究结果表明,研究区内蒸降比较大,一般达到2:1以上,剖面土壤水分随蒸发、入渗过程呈现相应的转化;强烈地表蒸发作用下,地下水对上层土壤水分具有明显调控作用,土壤水分在50cm以下相对稳定,50cm以上受地表过程的影响变化较为显著。

| Abstract: | The soil water dynamics is the precondition to explore the formation and evolution of the sodic soil.Especially,in the shallow groundwater,the exchange of the soil water and groundwater has become one of the main factors to drive surficial eco-environment change.In order to get the dynamics of the soil water in the sodic soil region,the field experiment was conducted in Da'an Sodic Land Experimental Station of China in 2004.The results presented that the ratio of the evaporation to precipitation reached to ... |
