摘要:
运用数值模拟的方法,对明沟排水洗盐过程中土壤水盐运移动态进行了研究.在沟距一半处土壤水盐运移可近似视为一维运动,冲洗脱盐率与脱盐深度最小,并沿这一位置形成对称分布;整个冲洗过程中,含盐量的变化总是稍滞后于含水率的变化;分析冲洗后不同含盐量剖面的返盐率发现,返盐率与含盐量符合幂函数关系,含盐量较低时,返盐率较高,反之亦然;运用数值模拟方法,建立了区域不同含盐量情况下明沟排水洗盐沟距一半处的洗盐制度.
Abstract:
Dynamic of soil water and salt of salt leaching with drainage ditch was studied by making use of numerical methods in this paper.Soil water-salt transport could be considered approximately as one-dimensional movement at half distance of two ditches,in which ratio and depth of desalinization reached the minimum value and formed symmetric distribution.During the entire washing process,changes of salinity were always slightly lagged behind changes of moisture content.Through analyzing the resalinization ratio of different salinity profile after leaching,it is found that the relationship between resalinization ratio and the salt content followed the principle of power function.The salt leaching system of different salt content was established.
