摘　　要：以2003年以来全球12次M≥7.8级大震为例,从"一震多井"和"一井多震"两个不同的侧面,结合井孔的水文地质条件,依据水位同震异常变化的记录图形,分析福建省地下流体数字化观测网对不同方位的地震的远场效应。福建省数字化水位、水温资料对M≥7.8级大震产生远场效应所记录到的同震异常与震级、震中距、地震类型、地震所处的构造位置以及水点的水文地质条件等相关。Taking 12 global earthquakes （M〉7.8） since 2003 as examples, from the view of ＂one earthquake corresponding to many wells＂ and ＂one well corresponding to many earthquakes＂, we analyzed the far field effect of groundwater observational network in Fujian Province with water level data and hydrogeologic condition. The results show that the anomalies of water level and temperature in Fujian Province that produce by the far field effect of these earthquakes is relevant to the magnitude, epicentral distance, earthquake type, tectonic location.
