摘　　要：对北京地磁台建台以来,台站周边环境随着北京城市化进程发生的变化做了较详细的描述。利用几次在台站地磁观测区范围内的地磁场梯度观测资料,分析了台站地磁观测场地磁场梯度的变化情况,并对现有地磁场梯度环境进行了评估。为北京地磁台及全国其他台站,在现有条件下的地磁观测工作提供了有益的参考。In this paper, we describe the changes of geomagnetic environment in detail with the expanding of Beijing city since the Beijing geomagnetic observatory had been built. With the data of the geomagnetic gradients, which were obtained by observing several times in the whole geomagnetic observatory area in the past years, we analyze the changes of the gradients of the geomagnetic observatory field and evaluate the observation environment. The result is helpful for geomagnetic observation working at present.
