| 摘 要： | 济宁城区位于汶泗河冲积平原的前缘地带，孔隙地下水资源丰富，开采量多年来处于超采状态，1988年以来发生了地面沉降。经采取调整地下水开采井布局等措施后，城区地面沉降速率逐渐减小，而沉降漏斗随地下水的开采向城区北部、东北部转移，地面沉降值大于60mm的范围达到了145km^2证实地面沉降的发生完全受控制于地下水的开采程度。根据济宁市地面沉降的危害程度和破坏性，可将其造成的经济损失分为直接和间接经济损失，其中间接经济损失为全部经济损失的75％以上。

| Abstract: | Jining district locates in the front part of Wensihe alluvial plain and pore underground water is very rich. Due to many years overmining, surface subsidence happened in 1998. By adjusting underground water exploitation wells distribution, surface subsidence rate in districts is descending gradually. Accompanying with underground water exploitation, subsidence funnels transferred to south and southeast part, and the scope with the settlement value more than 60ram has reached 145kin^2. It is proved that surface subsidence is controlled by exploitation degree of underground water completely. According to damage degree of surface subsidence in Jining city, economic loss can be divided into direct and indirect loss, and indirect loss is over 75%. |
