摘　　要：整理泉州白水营地磁台历史资料时发现数据不正常,摘例分析1999年日均值差值曲线异常突跳的问题,查找环境变化干扰因素;再溯1988～1989年初鱼池铁丝影响磁变仪基线值突变及相关试验分析研究、剔除影响工作,强调地磁观测环境净化保护。Base on the abnormal situation of the old data of Baishuiying Geomagnetic Station of Quanzhou, we analyzed the problems of daily ranges curve abnormal jump in 1999, searched the effect factor of the environment variations disturbance; and traced back to the base-line jumping of the geomagnetism and some related experiments and work during the year 1988 to 1989. It is emphasized to purify and safeguard geomagnetic observation environment.

关 键 词：地磁观测环境 干扰影响 剔除异常量 净化保护
