近年来,国际水文地质学家对水文科学的发展给予了极大的关注。特别重视因全球变化引起的环境变化对地下水资源的影响和地下水资源的开发利用对全球变化的作用、反馈及其贡献。从地下水由自然资源向社会资源转变的过程中,对地下水研究的重心也发生了转移,即由水力学问题转向水资源管理问题;由资源问题转为环境问题;同时也开始了更大规模、更大时空尺度的,对全球变化影响的研究等等。中国北方大陆西起青藏高原,经黄土高原到东部辽阔的华北平原,构成闻名世 In recent years, international hydrogeologists have given great attention to the development of hydrological science. Particular attention is paid to the impact of changes in the environment on groundwater resources due to global change and the role, feedback and contribution of groundwater resources to global change. In the process of converting groundwater from natural resources to social resources, the focus of groundwater research has also shifted from hydraulics problems to water resources management issues; from resource issues to environmental issues; and at the same time, larger scale, Research on the effects of global change on a larger temporal and spatial scale, and more.
