摘　　要：从目前大连轻轨客车运行情况及对此进行的干扰测试与分析中可以看出对地磁观测环境的干扰量小于0.2nT的最小距离应在9km左右,主要来自于轻轨泄露电流产生的磁场和输电线路产生的磁场影响。当然,轻轨泄露电流产生的磁场随时间推移今后可能还会加大,需进一步进行追踪实验和分析论证。The influence of Dalian City railcar on geomagnetic observation have been tested and analyzed.The disturbance to geomagnetism observation during its operation currently is less than 0.2 nT with the distance of 9 kilometers or so.Much works have to be done because the influence caused by the leakage of electric current may be possibly increased with time.
