利用“子午工程”布设在赤道异常区深圳站的监测仪获得的2011年1月至2012年12月间的电离层闪烁和总电子含量（TEC）观测数据，分析了华南地区夜间TEC 耗尽事件与电离层闪烁之间的关系．结果表明：华南地区晚间多次观测到TE C耗尽和电离层闪烁同时发生的现象，强闪烁（振幅闪烁指数S4＞0．6）和TEC耗尽同时发生的比例高于弱闪烁（0．2＜S4≤0．6）和TEC 耗尽同时发生的比例；TEC 耗尽和电离层闪烁同时发生时，TEC耗尽持续时间和电离层闪烁持续时间呈显著正相关，相关系数达0．97，且ROTI指数和S4也呈正相关，相关系数达0．68；TEC耗尽最大值与电离层闪烁持续时间和S4最大值的乘积呈线性关系；华南地区夜间也观测到了TE C增强现象，但TE C增强与电离层闪烁之间无明显相关性．

According to the data of ionospheric scintillation and total electron content (TEC)observed from January, 201 1 to December,2012 by a monitor set at Shenzhen Station as a part of Meridian Space Weather Monitoring Pro-ject in equatorial anomaly regions in South China,the relationship between the TEC depletion and the ionospheric scintillation at the nighttime in South China was analyzed.The results show that (1 )there occurs frequent TEC de-pletion simultaneously with the scintillation;(2)the simultaneous occurrence of strong scintillation (S4 >0.6)and TEC depletion is more frequent than that of weak scintillation (0.2<S4≤0.6)and TEC depletion;(3)when the simultaneous occurrence appears,a positive duration correlation with a coefficient of 0.97 apparently exists between the TEC depletion and the ionospheric scintillation,and a positive correlation with a coefficient of 0.68 between the ROTI index and the S4 index also exists;(4)the maximum TEC depletion value is linear to the product of the scin-tillation duration and the maximum S4 value;and (5 )although TEC enhancements are observed at the nighttime in South China,they have no significant correlation with the ionospheric scintillation.
