中文摘要：

利用南极区域内的中国中山站GPS常年跟踪站（ZHON）和国际GPS服务站GPS观测数据,计算出2000—2006年期间南极地区上空高精度电离层电子总含量值,分别对极光区内、极光区外、极隙、极盖区的电离层电子总含量进行分析比较。结果表明,极光区外的电子总含量峰值要大于极光区内,极光区内的电子总含量峰值又大于极盖区,而每日电子总含量谷值（即最小值）则相差并不明显,这一空间分布特征与不同位置的不同太阳入射角以及地球磁场在高纬地区具有的特殊构型有关。

英文摘要：

Using the GPS observations from permanent GPS stations,Chinese Zhongshan Station and IGS（International GNSS Service） stations in Antarctica,the high accurate ionosphere TECs of polar area were calculated during 2000—2006,and TECs above GPS stations located in polar cap,polar cap edge,in and out of auroral zone were comparatively analyzed.The results show that,the daily maximum TECs in the auroral zone are smaller than that out of auroral zone,larger than that in the polar cap,but this difference isn＇t obvious on minimum daily TECs.This spatial distribution is related to different places,different solar incident angles and special structure of geomagnetic filed in high latitude regions.
