摘要
本文对福建省泉州地磁台白水营老址与丰州镇董埔村候选新台址，使用高灵敏度，快速记录的磁通门磁力仪，对台址周围观测环境进行了全面对比监测，从地磁短周期脉冲干扰、地磁场变化形态、日变幅、时均值相关分析等方面进行评估，指出老址的周围环境干扰量已超出０．１ｎＴ的《地磁台站观测规范》要求，新址符合《地磁台站观测规范》要求，适宜建立永久性地磁基本台．
By using component fluxgate magnetometer of high sensitivity and high chartspeed,we have carried out geomagnetic variation observations at old site located atBaishuiying of Qianzhou Observatory and at new one as its candidate site located byDongpu village for comparison. The evaluation of the observation environment at thenew site has been made according to artifitial disturbances, morphology of the geomag-netic variations,amplitudes of the daily variations and relative analysis of hourly meanvalues.The results show that the environment disturbances at old site exceed 0.1nT,which is beyond the“standard”,and new site satisfies the“standard”.Therefore,itis suitable for establishing a permanent geomagnetic observatory.
