太原地震台短水准受水位影响分析及异常识别

Analysis on the water level affection and anomaly identification of short leveling in Taiyuan Seismic Station

水位是影响水准高差变化最为显著和普遍的因素，本文研究了晋7-1。井水位变化对太原地震台水准高差的影响，分析了两者的相关性及年最大变化量的异同情况。结果显示，相关性、年最大变化量比值异常与山西地震带地震有较好对应。

Water level is the most evident and normal factor affecting the short leveling. In this arti- cle, short leveling in Taiyuan Seismic Station influenced by Jin 7-1 ~ Well is studied. The similari- ties and differences of their relativity and max variety are analyzed. The result reveals the anomaly of their relativity and max variety is responded the earthquakes of Shanxi seismic belt.
