本文以新疆乌拉泊尔均衡场，新疆化肥厂试验站及昌吉地下水综合试验场资料求得的非饱和土壤水分特征曲线、水力传导度和土壤扩散率为依据，建立了适合乌鲁本齐地区非饱和土壤水分运动在蒸发条件下运用的数学模型．并用实测资料进行了验证．数值模拟结果与常观实测值有着良好的一致性，可应用于今后试验场在蒸发条件下土壤水动态的预报．
In this paper, based on the unsaturated soil water characteristic curve, hydraulic conductivity and soil diffusivity obtained from the Xinjiang UBP equilibrium field, Xinjiang Fertilizer Plant Experimental Station and Changji Groundwater Experimental Station, Mathematical model of saturated soil moisture movement under the condition of evaporation. And verified with the measured data. The results of numerical simulation are in good agreement with the observed values of normal observations and can be applied to predict the dynamic state of soil water under the condition of evaporation in the future.
