摘　　要：20世纪60年代初邯郸山前平原浅层地下水位大幅下降,地下水降落漏斗逐渐形成,地下水流场剧烈演变,采用时间序列分析、相关分析、水均衡等方法,分析了邯郸山前平原浅层地下水流场的演变规律及其驱动力,并计算了1981—2019年各影响因素对地下水流场演变的贡献率,结果表明:1960年以前邯郸山前平原浅层地下水流场演变主要受自然因素驱动,1960年以后地下水流场演变的驱动力由自然因素演化为人为因素和自然因素,地下水源汇项逐渐发生变化;邯郸山前平原排泄项对地下水流场演变的贡献率大于补给项,降水入渗和地下水开采始终是浅层地下水流场演变的主要驱动力;1981—2000年降水入渗补给量和开采量对浅层地下水流场演变的贡献率为80.82%,2001—2019年降水入渗补给量和开采量对浅层地下水流场演变的贡献率为75.79%,浅层地下水流场演变的驱动力趋于多元化。In the early 1960s,the shallow groundwater level in the piedmont plain of Handan had been decreased significantly,the falling funnel had been formed,and the groundwater flow field had evolved violently.The evolution process of shallow groundwater flow field in Han⁃dan piedmont plain was analyzed by using the theoretical methods of time series analysis,correlation analysis and water balance,and the contribution rate of various influencing factors to the evolution of groundwater flow field between 1981 and 2019 was calculated.The results show that before 1960,the shallow groundwater flow field in Handan piedmont plain is mainly driven by natural factors.After 1960,the driv⁃ing force of the evolution of groundwater flow field evolves from natural factors to human and natural factors,and the source and sink terms of groundwater are also changed gradually.The contribution rate of discharge term to the evolution of groundwater flow field is greater than that of recharge term.Precipitation infiltration and groundwater exploitation are always the main driving forces of the evolution of shallow groundw⁃ater flow field.From 1981 to 2000,the contribution rate of precipitation infiltration recharge and exploitation to the evolution of shallow groundwater flow field is 80.82%;From 2001 to 2019,the contribution rate of precipitation infiltration recharge and exploitation to the evolu⁃tion of shallow groundwater flow field is 75.79%.The driving forces of shallow groundwater flow field evolution tend to be diversified.
