| 摘 要： | 长江三角洲地区做为未来中国经济发展的一大重心，对该区地下水资源进行评价具有十分重要的意义。文章将该区作为一个整体来进行数值模拟，避免了以前将各行政区边界作为研究区边界分别来模拟各局部地区地下水资源量所带来的人为误差。对如此大面积、条件复杂的多层含水层系统，建立了反映该区地下水贮存和总体运移特征的三维模型，在采用地下水数值模拟国际通用标准软件GMS对其进行精细剖分的基础上，对模型参数进行了识别，进一步对该区地下水资源几种不同开采方案进行了评价，为该区今后建立水资源管理模型提供依据，为其经济发展规划和可持续发展提出合理的用水建议。

| Abstract: | The Changjiang (Yangtze) Delta is an important center area for Chinese economic development in the future, so the evaluation of the groundwater resources of this area is of great significance. In the previous studies, this area was divided into some subareas, according to the boundaries of the administrative districts, to evaluate their groundwater resources respectively, but the separation resulted in some human error. For the first time, the Changjiang Delta was considered as a whole in this paper, so such human error can be avoided. The three-dimensional model which describes the characteristics of the storage and the movement of the groundwater was built according to the multilayer aquifer system with large area and complex condition, the parameters of the model are identified on the basis of the fine division by GMS, which is the international common-used standard software for the numerical simulation of groundwater. Furthermore, some different exploitation alternatives of the area are evaluated. The results provide evidence to the building of management model of water resources in the future, and give some reasonable advices of exploitation to the project of economic development and sustainable development. |
