Abstract: The groundwater level in Gaoda, Kaiyuan and Yimen wells consistently represented rising since 2014 in southern Yunnan. After investigated the groundwater pumping around the wells, quantitatively excluded the influence of rainfall and calculated the stress state of aquifer system, as well as analyzed the surrounding area tectonic activity and the chemical component of three wells, we received the following results: The annual water level changes of Yimen well were mainly controlled by the rainfall, and the downward trend since 2003 and the upward trend in 2014 were closely related to the deep-well excavation and pumping of Dachunshu industrial park. The rising trend of water levels of the Gaoda and Kaiyuan wells since 2014 was not entirely controlled by rainfall, and had no direct connection with the exploitation of surrounding groundwater, either, it may be related to regional tectonic activities dominated by the north-south strong extrusion in recent years.
