摘　　要：通过长期监测,研究该区域地下水控采后的地面沉降特点和趋势。数据分析发现随着开采大幅减少,水位回升明显,地面沉降呈同步快速减缓;地面沉降由区域性沉降向城市和重点工程建设区等局部点状或小范围沉降发展的趋势;工程性地面沉降的监测与防治应成为今后地面沉降防治工作的重点;同时在控制地面沉降的前提下,尚可开采一定的地下水作为生活和应急供水水源。The long-term monitoring was done to study the subsidence features and trends after groundwater exploitation re- striction was implemented. Data analyses revealed water that the groundwater level has risen and ground subsidence slows down rapidly; ground subsidence changes from regional to local and pointed subsidence. Engineering ground subsidence moni- toring and control should be the focus in the future.
