从电离层电导率的理论研究出发,利用国际参考电离层模型IRI-2007,分析了地磁平静情况下,一个完整的太阳活动周期内,极区电离层Pedersen和Hall电导率在太阳活动上升相、下降相和高年的变化情况.研究表明,受太阳及地磁活动的影响,和电离层电子密度一样,极区电离层电导率具有明显的季节性特征,电导率在中、高纬地区均伴有比较明显的冬季异常行为.%Starting from the theory of ionospheric conductivity and make use of the international reference ionosphere model IRI-2007, Pedersen and Hall conductivity change in different phases of solar cycle during quiet time of the geomagnetic activity were discussed. The research show that influencing hy the solar and the geomagnetic activity, the ionospheric conductivity shows as an obviously seasonal feature and winter anomaly as the electron density shows, and which can appears at high-latitudes as well as at the mid-latitude.
