摘要：Abstract. Shanghai has a long history of exploitation and utilization of groundwater in order to meet the needs of industrial production and residential water. As a result, serious land subsidence disasters were induced. Land subsidence poses a huge security threat to the low-altitude coastal city of Shanghai. The development of land subsidence in Shanghai is closely related to the exploitation of underground water. In order to control land subsidence disasters, Shanghai has taken three key measures, i.e., the amount of compressed groundwater exploitation, the adjustment of groundwater exploitation level, and the implementation of artificial groundwater recharge, which have become the most effective measures for land subsidence control. However, as the groundwater levels of various aquifers in the region rise sharply, land subsidence is effectively controlled, and the measures of groundwater exploitation and recharge need to be dynamically adjusted to adapt to the current situation. In this context, from the perspective of history, the paper analyzes the long-term groundwater exploitation and recharge process and the development characteristics of land subsidence in Shanghai and studies the evolution process of land subsidence in different stages. From the perspective of land subsidence prevention and control, the paper analyzes the management measures of groundwater exploitation and recharge and the great achievements. The research results can provide a basis for land subsidence control and comprehensive groundwater management in the new period and can also provide a demonstration and reference for groundwater resource management in similar areas.
