摘　　要：为探讨山东省德城区深层地下水动态变化及流场演化过程,对德城区多年深层地下水开采量、水位及水质动态观测数据进行了详细分析.研究发现:经过50多年的开采,地下水流场发生了巨大的变化,降落漏斗中心位于陈庄乡张庄一带,水位标高-120 m左右,漏斗中心水位较开采初期下降了近140 m,整个德城区均被-50 m等水压线圈闭.深层地下水控制开采后,降落漏斗水平扩展及垂向下降速率都有不同程度的放缓,漏斗中心水位持续下降,但速率明显放缓,水力梯度下降,整体上趋于平缓.多年来深层地下水水化学组分比较稳定,水质并未发生实质性变化,受外界人为因素和自然变化影响较小.The dynamic changes of deep groundwater and the evolution process of flow field in Decheng district are studied.The data of deep groundwater exploitation in Decheng district,water level and water quality dynamic observation data are analyzed in detail.Results show that the groundwater flow field has undergone tremendous changes in more than 50 years of mining.The center of the funnel is located in Zhangzhuang area of Chenzhuang township.The water level is about-120 m,and the water level at the funnel center is nearly 140 m lower than that at the initial stage of groundwater extraction.The urban area is closed by water pressure line of-50 m.After deep groundwater control mining,the horizontal expansion and vertical decline rate of the falling funnel have slowed down to varying degrees,and the water level at the funnel center continues to decrease,but the rate slows down,the hydraulic gradient decreases,and the overall trend is flat.The chemical composition of deep groundwater has been relatively stable over the years,and the water quality has not changed substantially,and it is less affected by external human factors and natural changes.
