选取适应复杂上边界条件的一维分层土壤水分运动数值模型和Khepar模型，利用安徽蚌埠五道沟水文实验站蒸渗仪实测资料对两种模型模拟计算交替积水条件下降雨入渗补给量的能力进行了比较和分析。结果表明，复杂上边界模型在模拟计算交替积水条件下降雨入渗补给量时要优于K hepar模型，但两种模型的计算结果总体上均小于实测值。两种模型在模拟计算短时间强降雨条件下降雨入渗补给量时均较差。
選取適應複雜上邊界條件的一維分層土壤水分運動數值模型和Khepar模型，利用安徽蚌埠五道溝水文實驗站蒸滲儀實測資料對兩種模型模擬計算交替積水條件下降雨入滲補給量的能力進行瞭比較和分析。結果錶明，複雜上邊界模型在模擬計算交替積水條件下降雨入滲補給量時要優于K hepar模型，但兩種模型的計算結果總體上均小于實測值。兩種模型在模擬計算短時間彊降雨條件下降雨入滲補給量時均較差。

Choosing the one-dimensional layered soil moisture movement numerical model adapting complicated upper surface bounda‐ry conditions and Khepar model ,the simulation functions of these two models are examined by the observation data of the Wudaogou Hydrological Experiment Station ,Anhui province .The results show that the complicated upper surface boundary condition model is better than Khepar model in calculating the precipitation recharge under intermittent ponding and drying conditions .But the simula‐tion value of two models are less than measured value .The results of the two models calculating the precipitation recharge under the heavy rainfall in a short time conditions are poor .
