摘　　要：有限差分法和有限单元法一直在地下水数学模拟中处于主要地位,但这两种方法均存在一定的缺陷。针对这两种方法的现有缺陷,许多专家学者提出了不同情况下克服这些缺陷的新方法,从而建立新的模型。这些模型在实例中都能与实测数据达到很好的吻合,证明了这些模型的可行之处。但是,每种方法各有其自身优缺点和适用范围,所以应当根据具体条件适当选择方法来建立地下水数学模型。The finite difference method and the finite element method have been in the dominant position in the simulation of groundwater, but they have their own shortcomings. In light of this situation, many experts proposed new method to overcome these shortcomings in different situations. So as to establish a new model and these models can anastomosised with the actual measurement data in the actual situation, this proved that the model is feasible. However, each method has the advantage and the scope of application on the basis of its own shortcomings. We should choose a different method to create a mathematical model of groundwater according to different conditions.
