摘要： 本文依据浅层地下水系统的特点,把地下水系统放在降水－地表水－地下水的整体水文循环中来研究。建立了以地下水位为参数的水量转换模型,并在地下水运动基本微分方程的差分离散式中进行线性化处理。同时考虑浅层地下水系统输入信息的不确定性。从而构造了一个考虑三水转化关系和随机输入倍息的浅层地下水系统模型,并给出了应用实例。

Abstract: According to the characteristics of the shallow ground water system,the authors study the ground water system from the angle of the whole hydrological circle which includes the precipitation, surface water and ground water. A stochastic model is used to generate the input factors and boundary conditions of the model,and empiral expressions are suggested for the estimation of water exchange. The governing equation of the ground water flow is solved on the basis of the Integrated Finite Difference Methed. An example of the medel shows that the results are reasonable.

Key words: shallow ground water system, simulation model, stochastic model
