摘要
本文给出了边界拟合坐标系下的二维地下水流的基本方程．并且用该坐标系下的有限差分法（ＡＤＩ法）对江苏某市的承压水和潜水资源进行评价．预测了１９９１—２０００年的地下水流场，边界拟合坐标下的ＡＤＩ法的计算结果和实测水位比较一致，表明该方法在地下水资源评价中有实际应用价值．尤其在处理边界几何形状复杂的地下水流问题时更为有效．
This paper describes the application of the finite difference method of boundary fitted coordinates in groundwater resources evaluation.A 2-dimensional groundwater flow equation in the boundary fitted coordinates is derived. Numerical calculations by ADI method are carried out for confined water and phreatic water resources in a city of Jiangsu Province.The results are compared with obserued heads in May, 1991 and the agreement is satified.It is proved that the method proposed in this paper is of practical value to the hydrogeological computation.
