摘　　要：基于地球物理数据跟踪分析成果,总结近年来我国地震地球物理台网观测环境干扰情况,分析环境干扰的时空分布特征,并介绍主要干扰及其典型形态特征。针对常见环境干扰,指出几种措施和方法,为干扰的抑制与排查提供参考。Based on tracking and analysis results of geophysical data,this paper summarizes the observed environmental interference of seismic geophysical networks in China in recent years,analyzes the spatial and temporal distribution characteristics of environmental interference,and introduces the main disturbances and their typical morphological characteristics.For common environmental interferences,several measures and methods are proposed,which can provide a reference for suppression and investigation of interference.
