| 摘 要： | 2014年以来，滇南地区高大、开远和易门3口井的井水位出现趋势上升现象。通过开展井孔周边地下水开采情况的调查、降水影响的定量排除、井孔含水层系统应力状态的定量计算、周边区域构造活动的分析以及井孔水体化学组分的分析等工作，认为易门井的水位年动态主要受控于降水，2003年以来的趋势下降和2014年的趋势转折上升与大椿树工业园区的深井开挖抽水密切相关；高大井和开远井的井水位自2014年以来的趋势转折上升现象不完全受控于降水，但与周边地下水的开采亦无直接联系，可能与近几年该区域南北向强挤压为主的构造活动有关。

| 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. |
