Short summary
This article established a groundwater–subsidence model in a typical land subsidence region and classified an early land subsidence warning zone based on the results from the model. If the pumping of groundwater from the second and fourth aquifers was reduced by 50 % and pumping from the third aquifer was reduced by 60 %, the early warning level for land subsidence would be greatly reduced and would meet the requirements for land subsidence control.
