中文摘要：
对盐渍土中的水盐动态进行定量分析是提出适宜于宁夏银北地区盐渍土调控措施的基础工作。蒸发条件下土壤水分运动模拟初步研究表明,将有限体积法应用到求解蒸发条件下的土壤水分运动模拟计算中,模拟值与实测值吻合较好;春季土壤含水率模拟曲线在纵断面较为一致,地表蒸发量对0.2-0.6m的土壤含水率有较大的影响。
英文摘要：
It＇s the basis of the work to use the numerical simulation method for finding appropriate control measures in Yinbei region of Ningxia province. The results showed that there was a good agreement between simulated and measured values when the finite volume method was selected to simulate the movement of soil moisture evaporation. The simulated curve of soil moisture in the horizontal section was consistent with that of the real values. Surface evaporation had a greater impact on the soil moisture of 0.2-0.6 m.
