摘　　要：基于水文地质参数时变特性客观存在的事实,考虑水文地质参数为常量及参数随时间发生变化的情况下,推导了交替方向隐式差分法计算地下水二维非恒定流的方程,并引入算例分别进行计算,得出水文地质参数的时变特性对地下水非恒定流的计算存在影响的结论,进一步验证了水文地质参数研究工作的重要性与必要性。Based on the analysis of hydro-geologic parameters＇ time variability, considering the different condition that hydro-geologic parameters are as constant or change with time, The authors deduce alternating direction implicit difference method and equation to calculate two-dimensional unsteady underground water. Then perform calculation with examples in detail, and draw the conclusion that the time variability of hydro-geologic parameters affect the calculating results of underground water unsteady. In further, it explains the importance and necessity to work on the research of hydro-geologic parameters.
