摘　　要：研究水文地质参数随时间变化的特征及机理有利于深入了解地下水系统特性。地下水位微动态对于天然周期性荷载固体潮及气压加载作用的响应则提供了一种经济有效的含水层水文地质参数计算方法。系统梳理了地下水对于固体潮响应、气压响应以及综合固体潮及气压响应求解参数的理论模型,介绍了井-含水层系统受地震及采矿活动影响过程中水文地质参数随时间变化的情况。气压响应方法也可用于含水层脆弱性的评估。分析认为,研究地下水位微动态有利于在时间及空间尺度上了解地壳运动及人类活动对含水层系统的影响。最后提出了该领域未来研究方向主要包括:井孔皮肤效应及储积效应的应用、结合多种确定基础地质参数的方法提高水文地质参数计算精度、探索地下水超采及地面沉降等其他人类活动对区域尺度含水层系统的影响。[Objective]In order to understand groundwater systems,it is useful to study the changing characteristics and mechanisms of hydrogeological parameters with time.Responses of groundwater level microfluctuations to natural periodic loadings,such as earth tides and barometric pressure,serve as low-cost and effective investigation technique to calculate aquifer hydrogeological parameters.[Methods]In this paper,we systematically reviewed theoretical methods of hydrogeological parameters estimation based on groundwater level response to earth tides,barometric pressure,and their combination.We presented earthquake-related and mining-related parameters change with time in well-aquifer system.The barometric pressure response method also applies to the assessment of aquifer vulnerability.[Results]We conclude that studying the microfluctuation of groundwater level may provide insight into the interaction among hydrogeological processes,tectonic activities,and artificial influences in the shallow crust at spatial and temporal scales.[Conclusion]This paper also proposes three scientific problems to be solved in the future:the application of skin and wellbore storage effects,the improvement of computation accuracy of hydrogeological parameters by combining multiple methods for determining basic geological parameters,and the investigation of other artificial influences such as groundwater overdraft and subsidence to regional aquifer systems.
