摘　　要：对北京国家地球观象台2008年1月—2014年12月地震前兆观测手段地磁、形变和重力干扰,从环境干扰、人为干扰和其他干扰,对观测产生干扰原因、干扰记录特征进行分析,并对各项干扰及时采取合理、有效的解决措施,提高地震前兆资料的使用价值。In this paper, we analyzed the magnetic, ground deformation and gravity data collected in Beijing National Earth Observatory, from January 2008 to December 2014. Three factors,including the environmental, artificial and other disturbances are thoroughly considered to summarize the characteristics of the each kind of noise. And their particular reasons are analyzed.Finally, we have taken effective measures to solve each of the interruptions based on the above analysis. Therefore, the earthquake precursory data can be better used.
