【摘要】 本论文综述了水资源评价的意义，水资源评价的现状及发展趋势，水资源评价的各种方法及其对比。选择了有限单方元法作为本研究的数值评价方法。简述了有限单元方法的原理及利用有限单方元方法进行地下水资源评价的步骤。 重点研究了新疆及西北干旱半干旱地区山前洪积扇—冲洪积平原含水层多层结构的特点，用潜水、承压水等基本的地下水模型子系统，构成了这种典型地区的地下水系统模型，并较好的处理了各子系统之间的关系。研究了地下水系统的动态特征并提出了若干处理方法。 新疆阿图什哈拉峻盆地地下水系统即属于上述典型的多层含水层系统，采用有限单方元法对不同性质含水层地下水流方程进行了数值离散，对各含水层的关系进行了较好的处理，成功地实现了哈拉峻盆地地下水动态数值模拟，并进行了多种开采方案的预测预报。更多还原
