【摘要】The temporal and spatial distribution of scintillations accompanied with Total Electron Content (TEC) depletions,scintillations with no TEC depletions,and TEC depletions with no scintillations are discussed.The data of ionospheric scintillation and TEC from January 2011 to December 2012,and from January 2015 to December 2015 are observed by the monitor setting at Shenzhen GPS station.The results show that these three types of events occurred mainly in spring and autumn.These three types of events occurred mainly from 19°N to 23°N,21°N to 24°N and 24°N to 26°N,respectively.In addition,these three types of events occurred mainly from 20:00LT to 22:00LT,21:00LT to 23:00LT,22:30LT to 23:30LT,respectively.The temporal and spatial distributions of these three types of events are responsible for the evolution process of equatorial plasma irregularity over South China.%利用位于赤道异常区的深圳站(22.59°N,113.97°E) 2011年1月至2012年12月及2015年1至2015年12月监测到的GPS-TEC数据,统计分析华南地区电离层闪烁与TEC耗空同时出现、电离层闪烁单独出现和TEC耗空单独出现3种现象的时间和空间分布特性.结果表明:这3种现象均主要发生在春秋季节;闪
