摘　　要：使用高灵敏度的Ｇ８５６、ＤＴＺ２ 型核子旋进式磁力仪，对乌鲁木齐地磁台１９９ 个测点的磁场梯度进行了复测。经过严格的数据校正处理，重新作出了ΔＦ等磁力线图，并分析讨论了台站院内环境磁场的变化特征。测量结果表明：乌鲁木齐地磁台仍处于磁场正常区，工作环境符合《地磁台站观测规范》要求。The magnetic field gradient is surveyed again at 199 sites in Urumqi geomagnetic station using high sensitivity nuclear procession magnetometers of Type G856 and DTZ 2.The contours of ΔF are drawn based on the survey data that are correctted strictly,and the varying characteristics of the ambient magnetic field in the yard of Urumqi geomagnetic station are analyzed and discussed.The survey result shows that the Urumqi geomagnetic station still located in the normal region of geomagnetic field and the working surroundings satisfies the needs of 《Observing Standard for Geomagnetic Stations》.
