中文摘要：

正确认识地下水资源在区域发展中的重要作用,对于提高政府和公众对地下水资源的认知水平,实现地下水资源合理利用具有重要意义。文中通过地下水资源及其开发利用的现状和未来供需形势分析,详细阐述了地下水在京津唐区域社会经济发展中的重要作用,结果显示：地下水资源占京津唐地区总水资源的65%,地下水对总供水的贡献率可达62%;由于气候旱化,地表水资源的持续衰减,在南水北调供水前仍需超采地下水来维持区域社会经济的稳定发展;即使在南水北调供水的条件下,地下水对总供水的贡献率仍维持在30%～40%的水平,对区域社会经济发展具有不可替代的作用;地下水系统的调蓄功能将在京津唐地区未来社会经济发展中发挥积极作用。

英文摘要：
