| 摘 要： | 电离层TEC（Total Electron Content）扰动与多种扰动源相关联．2009年6至7月期间存在地震和日全食的扰动源．利用广州地区GPS监测网在2009年6至7月连续监测到的TEC数据，通过采用前15天数据的滑动窗口对数据进行处理，从时间序列和空间分布两方面分析了华南地区电离层TEC扰动特征．结果显示，2009年6至7月华南地区电离层TEC扰动和该时期发生的地震以及日全食事件可能有关联；2009年7月多个地震发生引起的电离层扰动特征为，震前出现的是正异常，发震当天或震后有可能是正异常，也有可能是负异常；7月22日日全食当天TEC扰动为正异常，推测该正异常是地磁活动、地震活动及日全食综合效应的结果．

| Abstract: | There are many origins of ionospheric TEC(Total Electron Content) disturbances during June-July 2009,including several earthquakes and a total solar eclipse.In current study,using the GPS-TEC date observed during June-July 2009 in Guangzhou GPS station and processed by a sliding window with the data of prior 15 days,the characters of South China ionosphere are investigated in spatial and temporal distribution.The results indicate that there are possible relations between the South China ionospheric TEC dist... |
