拉萨地磁台是我国海拔高度最高的一个地磁台站。1957年7月1日正式投入观测。台址在拉萨河谷盆地中央,地面两公尺以下为砾石冲积层,地面磁场梯度为1纳特/米,分布比较均匀。拉萨地磁台从建台至今已近三十年,其间取得了较连续可靠的地磁观测资料。为探讨该台地磁场的变化规律及特征,本文利用已正式出版的拉萨台《地磁观测报告》1—18卷(1957—1974年)和1975—1984年部分绝对观测仪器直接观测的资料
Lhasa geomagnetic station is a geomagnetic station with the highest altitude in China. July 1, 1957 formally put into observation. The site is in the center of the basin of Lhasa River Basin. The gravel alluvium is below two meters below the ground. The gradient of the ground magnetic field is 1 Nm / m and the distribution is relatively uniform. For nearly 30 years since its establishment, Lhasa Geomagnetic Station has made more stable and reliable geomagnetic observational data. In order to explore the changing regularity and characteristics of the magnetic field of the platform, this paper utilizes the officially published data of LST stations 1-18 (1957-1974) and direct observations of some absolute observational instruments from 1975-1984
