摘　　要：地下水水流运动有很大的随机性,随机理论方法把地下水系统中的参数看成具有空间分布的随机场,可以对水流的不确定性和空间变异性进行模拟。该文介绍了地下水动态数值模拟中随机方法的原理、适用条件及存在的问题,重点讨论了国内外地下水动态随机模型的研究应用以及各种随机估参方法。文章还提出了此领域今后的发展方向,具有一定的借鉴意义。Groundwater flow is greatly stochastic. Stochastic theory method can simulate uncertainty and spatial variability of water flow, considering the parameters of groundwater regime as random field with spatial contribution. This paper has reviewed the basic principle,applicable conditions and unsolved problems of stochasitcally numerical simulation of groundwater regime. Especially, it has generalized the study on stochastic models of groundwater in domestic and abroad and the methods to evaluate stochastic parameters in detail. This paper has also showed the development direction of stochastic method in this field, which is useful to some purpose for the future work.
