基于地质环境、场地条件、地磁场观测环境和背景噪声等,对银川地磁台迁建场地进行调查与测试,结果表明,该场地四周无大型建筑物,周边1 km范围内地势相对平坦,无发射塔、铁路、公路主干线、高压线路及变电站等干扰源。分析认为,该台迁建场地地理位置优越,电磁观测环境较好,满足地磁台建设规范的技术要求。
Based on the geological environment, site conditions, geomagnetic field observation environment, and background noise, an investigation and testing were conducted on the relocation site of Yinchuan Geomagnetic Observatory. The results showed that there were no large buildings around the site, and the terrain within 1 km of the site was relatively flat, with no interference sources such as transmission towers, railways, highway main lines, high-voltage lines, and substations. Analysis shows that the relocation site of the station has a superior geographical location and a good electromagnetic observation environment, meeting the technical requirements of the geomagnetic station construction specifications.
