摘　　要：磁场梯度测量是选建地磁测点过程中的一项重要工作。在田庄、灵山、东兴庄测点周围，进行了磁场梯度的一般测量与详细测量，结果显示，各测桩的水平方向与垂直方向的磁场梯度均不大于１．０ｎＴ／ｍ。完全符合磁测规范的要求。The gradient measurement of magnetic field is an important work during the process ofselecting and building geomagnetic sites,The general and detailed gradient measure-ments of magnetic field were done around the Tianzhuang,Lingshan and Dongx-ingzhuang sites,The results show that the gradients of magnetic field in horizontal andvertical directions at various points are not greater than 1.0nT/m,and it is agreementwith the regulation of geomagnetic survey.
