摘要
By the end of October 2005, all of the 4 831 extraction wells were completely closed, which reduced groundwater exploitation by 2.8 billion cubic meters. Since then, the groundwater level in this area has achieved varying degrees of restoration, and most of the ground settling velocity have slowed down significantly. Based on the monitoring data, the authors made a further exploration on the characteristics of land subsidence.
