摘　　要：梳理了河北地球物理站网7个中心站48个站点涵盖的场地环境典型事件,涉及到形变、地电、地磁和流体4个学科。全年共记录到事件91条,受影响仪器26套。选取典型的高压直流输电、设备漏电、水(油)井泉抽水、水库水位涨落等影响因素进行分析。对事件发生过程进行详细分析,找到其规律及原因,提出有效的解决方法,为异常核实,分析预报提供参考。In this paper,the typical site environmental events covered by 48 stations in 7 center stations of Hebei geophysical station network are reviewed,involving deformation,geoelectricity,geomagnetic and fluid disciplines.According to the number of recorded events and the number of affecting instrument sets,typical influential factors such as HVDC transmission,equipment leakage,water(oil)well spring pumping,and reservoir water level fluctuation are selected for analysis.The process of occurrence of the event is described in detail,its rules and reasons are found,and effective solutions are proposed to provide reference for anomaly verification,analysis and prediction.
