地理信息系统（GIS）是水文地质研究的一个重要工具，地理信息系统在水文地质领域的应用是水文地质研究的热点之一。在总结近年来国内外大量相关研究成果的基础上，从基于GIS的地下水资源评价、地下水资源管理、地面沉降、地下水水质评价及污染物分析、水文地质调查、地下水保护，以及GIS与数值模拟技术的结合等方面介绍了地理信息系统在水文地质领域的最新应用，提出了GIS在水文地质领域应用存在的问题，并对今后GIS在水文地质领域的应用进行了展望。指出，今后应加强GIS与地下水模型及分布式水文模型的集成、基于GIS的地下水系统真三维或四维可视化、网络GIS技术的应用，以及流域水资源综合管理评价系统的建立等方面的研究。

Geographic Information System (GIS) is an important tool for hydrological geology research, and its application in hydrogeology field is one of the hot issues in groundwater research. The latest application of GIS to groundwater was introduced from seven aspects: groundwater resources evaluation, groundwater resources management, land subsidence, groundwater quality evaluation and pollutants analysis, hydrogeology survey, groundwater protection, and the combination of GIS and numerical simulation technology. At the same time, problems of GIS application in the field of hydrogeology were presented, and the development of GIS in hydrogeology field was discussed. In the future, what should be strengthened includes the integration of GIS and groundwater model and distributed hydrological model, the visualization of 3D or 4D groundwater system based on GIS, the application of web GIS technology and the establishment of comprehensive systems for water resources management and evaluation in a basin.
