| 摘 要： | 通过室内试验,采用控制土壤水流速和入渗水量的方法,研究了不同土壤水流速和入渗水量对土壤脱盐效果的影响。试验结果表明:入渗流速与入渗水量都是影响土壤脱盐效果的显著因素。入渗过程中,水分在土壤中的渗透流速越慢,脱盐效果越好;渗透水量和与之对应的单位水量排盐率呈极显著的幂函数递减关系。

| Abstract: | The effect of desalting was studied under different infiltration conditions.Results showed that water amount of infiltration and flow velocity have obvious effect on desalting effect.In course of infiltration,the desalting effect is better under slow flow velocity than fast flow velocity.There are very prominent power function relationship between the infiltration water amount and its desalting rate of per unit water amount. |
