| 摘 要： | 介绍了大量的关于地震电离层扰动现象研究的最新进展，研究表明地震发生前的几天或者几个小时电离层扰动被观测到，电离层前兆是确实存在.但要将震前的电离层扰动作为地震短临预报的工具，还有许多值得我们去深入研究和解决的问题.应用空间技术开展大区域范围内电离层参数的实时观测，如用地震电磁卫星、GPS台网、并和地面电离层垂测仪观测相结合，建立“电离层地震前兆监测系统”，无疑会加速这项研究的进程.

| Abstract: | This paper accumulates the recent advances in ionospheric disturbances of earthquake.The results brought out clearly that ionospheric disturbances appearing few days or hours prior to earthquakes can be observed.This means that ionospheric precursors do exist associated with earthquakes.However,if we take ionospheric variations as a tool for short-term predictions before earthquakes,we still have a long way to go.We should adopt space technologies in monitoring the spatial variations of plasma parameters and built the monitoring system of ionospheric precursors of earthquakes which consists of seismo-electromagnetic satellite,GPS network and ground-based ionosondes.These measures undoubtedly speed up the research of seismo-ionospheric precursors. |
