摘　　要：胶东半岛是我国典型的缺水山区,广泛分布有岩浆岩、变质岩及白垩系弱透水性岩层,含水层富水性差异大,同时胶东半岛地区人类活动密集,水质型贫水问题同样突出,资源型缺水和水质型缺水同时存在。为揭示人类活动影响下典型缺水山区蓄水构造模式和找水方向,通过2019~2022年在胶东半岛典型缺水山区开展的水文地质调查,采用本次施工的7组钻孔数据,7组水化学和同位素分析样品,基于蓄水构造理论,结合人类活动影响下的水化学和同位素特征,对比研究不同类型蓄水构造富水性和以硝酸盐为代表的人类活动对水质的影响。提出了洼地沟谷风化壳型、接触带型、断裂型、岩溶型4种蓄水构造模式。揭示了受人类活动影响,以洼地沟谷风化型蓄水构造为代表的风化裂隙水硝酸盐含量升高,水质较差,适宜工农业生产用水;断裂型蓄水构造为代表的构造裂隙承压水,上部完整基岩作为隔水盖层减轻了人类活动对地下水质的影响,硝酸盐含量低,水质较好,适宜城镇、农村生活用水;接触带型和岩溶型蓄水构造开发利用方向则与其含水层埋深有关。Objectives:Jiaodong Peninsula is a typical water-scarce mountainous area in China,where magmatic rocks,metamorphic rocks and chalk impervious sandstones are widely distributed,and aquifers differ greatly in water richness.Meanwhile,there are intensive human activities in Jiaodong Peninsula,and the problem of poor water quality caused by poor water quality is also prominent,and resource-based water shortage and water quality poor water shortage problems exist simultaneously,In order to reveal the water storage structural model and water seeking direction of typical water-scarce mountainous areas under the influence of human activities.Methods:The hydrogeological survey conducted in the typical water-scarce mountainous areas of Jiaodong Peninsula from 2019 to 2022,using 7 groups of borehole data,7 groups of hydrochemical and isotope analysis samples from this construction,based on the theory of water storage structure and combined with the water chemical and isotope characteristics under the influence of human activities,the water richness of different types of water storage structures and the influence of human activities represented by nitrate on water quality were compared.Results:In this paper,the structure of the water storage structure of the depression,the contact band,the fracture and the karst type are summarized.It is revealed that the nitrate content of the weathered fissure water represented by the weathered water storage structure in the depression and gully is increased and the water quality is poor due to human activities,It also revealed that the water is susceptible to human activity,the nitrate content is raised,the water quality is poor,the complete bedrom of the confined water layer is the influence of human activity on the groundwater,the low nitrate content and the water quality.The upper intact bedrock of structural fissure water(confined water)represented by fault-type water storage structure acts as a water barrier covering layer,which weakens the influence of human activities on groundwate
