中文摘要：

利用2002年2月至2007年12月海南地区DPS-4测高仪观测数据，用统计分析方法研究了磁暴对电离层扩展F的影响．结果认为磁暴从整体上抑制了扩展F现象的发生．但若把扩展F分为不同类型，则结果却有所不同．对于频率型（FSF），在2002年和2003年磁暴对其有促发作用，在2004-2007年有抑制作用；对于区域型（RSF），在2002--2005年磁暴对其有抑制作用，在2006年和2007年，对其有弱促发作用；对于混合型（MSF），在2002年磁暴对其有抑制作用，在2003年和2004年有促发作用，从2005年开始，磁暴对其有抑制作用；对于强区域型（SSF），在2002--2004年磁暴对其有抑制作用，在2005年和2006年有促发作用，2007年有弱抑制作用．

英文摘要：

Using the data observed with DPS-4 ionosonde from February 2002 to December 2007, influence of geomagnetic storm on the ionospheric Spread-F （SF） in Hainan region is statistically studied. The result shows that the occurrence of Spread-F as a whole is suppressed by the storm.But for the different type of SF, influences of the storm are different. During storm time, FSF is motivated in 2002 and 2003, and suppressed during 2004--2007; RSF is suppressed during 2002-- 2005, and motivated in 2006 and 2007; MSF is suppressed in 2002, motivated in 2003 and 2004, and suppressed again during 2005--2007; SSF is suppressed during 2002 2004, motivated in 2005 and 2006, and weakly suppressed in 2007. These results are important to study the mechanism for different type of ionospheric SF during the storm time in the low latitude region.
