用四个经度链附近电离层垂测资料，分析1986年2月6－10日磁暴期间的电离层扰动现象。磁层－电离层间电动耦合的东向电场是造成多站f0F2同时突增的主要机制。扰动的赤道电集流使'喷泉效应'增强对赤道异常驼峰区f0F2增高也起重要作用。磁暴后期，电离层扰动发电机电流系在低纬区的西向电流、电场使F层电子密度下降，而赤道区'喷泉效应'减弱的结果则是驼峰区各站f0F2明显下降的原因。
The ionospheric disturbances during the geomagnetic storm from February 6 to 10, 1986, were analyzed using vertical ionospheric data from four longitudes. The eastward electric field of the magnetosphere-ionosphere electromechanical coupling is the main mechanism that causes the simultaneous increase of multi-stations f0F2. The disturbed equatorial current collection makes the increase of fountain effect also play an important role in the increase of f0F2 in the equatorial anomalous hump area. In the late stage of the storms, the generator current perturbed by the ionospheric system was in the westward direction in the low latitudes. The electric field decreased the electron density in layer F, while the decrease in fountain effect in the equatorial zone resulted in a significant decrease in f0F2 at each station in the hump area.
