摘　　要：系统阐述了非充分灌溉条件下农田土壤水分动态变化的二种模拟模型 ,即大田水量平衡模拟模型和土壤水运动模拟模型 ,提出了农田计划湿润层土壤含水量非线性变化的计算方法 ,结合实例对二种模型进行分析比较 ,为非充分灌溉决策提供了新的理论依据。Two models of simulating soil water movement under deficit irrigation, i.e. field soil water balance model and soil water dynamics model, are introduced and analyzed in this paper. The calculating method for determining nonlinear soil water function within designed wetting layer also been presented. A case study was used to check the two models and results shows that the models are reasonable and suitable for using as new theoretical bases for deficit irrigation design.
