中文摘要：

利用2000—2006年南极中山站GPS观测数据，研究中山站电离层TEC随太阳活动、地磁环境、单日、年和季节变化的特征。结果表明，GPSTEC随太阳活动和地磁环境的影响呈线性变化特征，单日、年和季节性TEC变化表现出电离层气候学特征的同时，也出现了磁中午异常的极区特性。

英文摘要：

Precise ionosphere TEC values are derived from perennial GPS observations during 2000 -2006 at Antarctic Zhongshan station, the characteristics of TEC associated with solar activities, geomagnetic environment, and the daily, annual and seasonal TEC variations are studied. Results show that GPS-TEC linearly changed with the influence of solar activities and geomagnetic environment while elimatologie characteristics of ionosphere are reflected in daily, annual and seasonal TEC variations, as well as polar characteristics of magnetic noon anomaly oecurr.
