摘　　要：地下水资源短缺是制约我国长期发展的重要因素,尤其是我国北方地区,地下水资源相对较贫乏,地下水资源具有极其重要的战略地位。随着经济发展,对地下水需求量日益增长。通过对官厅水库南岸盆地水资源调查,分析区域的地形地貌、新近系以来研究区域盆地发展和水系演变、地层岩性以及水文地质资料,结合现场水文地质勘察论证,深入分析工程区水文地质条件、含水层特征及地下水资源量,认为工程区松散层渗透性整体较弱、富水性差、可持续供水保证率低,且地下水已处于超采状态,不宜作为现代工业用水的地下水源,寻找大型地下水源地尽量避开该区域。The shortage of groundwater resources is a critical issue that constraints the long-term development in China,especially in the northern regions where groundwater is relatively scarce.Water resources have an extremely important strategic position.With economic development,the demand for groundwater is steadily increasing.Through the investigation of water resources in the southern basin of Guanting Reservoir,this paper analyzes the region’s topography and geomorphology,the development and evolution of the basin and water system since the Neogene period,stratigraphic lithology,and hydrogeological data.Combined with on-site hydrogeological surveys and evaluations,an in-depth analysis of the hydrogeological conditions,aquifer characteristics,and groundwater resources in the project area is conducted.The findings indicate that the loose sedimentary layers in the area have generally low permeability and poor water yield,resulting in a low reliability of sustainable water supply.Additionally,the groundwater is already over-exploited,making it unsuitable as a groundwater source for modern industrial use.Therefore,it is recommended to avoid this area when searching for large-scale groundwater sources.
