摘　　要：根据观测系统的检查、测区观测环境调查、辅助资料等变化对太原台水准异常变化的影响进行分析认为,该台观测资料可信,但存在地下水位变化的影响。对井区附近同层抽水井开采情况调查表明,太原台水准2009年以来的反向上升与附近小煤窑关闭、采水减少、水位回升有关。Based on the investigation of observation system,observation environment and auxiliary material,we think that the leveling deformation anomaly of Taiyuan station is credible,but it is affected by the change of water level.Through the investigation on exploitation of the pumping wells with the same layer,the reverse rising of leveling in Taiyuan station is associated with the recovery of water level because of small coalmines that have been shut down since 2009.
