摘　　要：介绍了乌鲁木齐地磁台测量标志方位角的方案、测量方法、原理。利用已有的观测成果,采用几何转换的方法精密测量了新建成观测室内的6个观测墩相对于2个方位标志的方位角,成功的将旧观测室原标准墩方位角数据迁移到新观测室内各观测墩上,观测精度符合技术规范的要求,使新观测设施能够及时投入到观测工作中。并对地磁观测环境改造完成后的全面测量工作作出规划,在知识、技术上都做好了准备。The plan, methods and principle of azimuth survey was introduced for Urumqi geomagnetic station marker. Combined with the already available observation results, the Geometric Data Transfer Method was used to survey the azimuth of 6 observation posts, in the new observation room, relative to 2 compass markers precisely. The azimuth of standard posts in the old observation room was introduced to every post in the new observation room successfully and the observation accuracy met the require of technical specification, which made the new monitoring facility to be used in daily observation as soon as possible. A new complete survey planning was made after the environmental reform of geomagnetic observation.
