备注

回顾了GPS技术应用于我国地震监测中的发展历程,重点从GPS数据处理与时间序列、中国大陆构造变形速度场与应变率场、中国大陆活动地块运动定量化和地震研究等方面,介绍了GPS在我国地震监测中的应用现状,并针对当前面临的问题与挑战,进行了讨论,从地震预测研究、基础研究、GPS台网监测布局和GPS解算精度与时效4个方面,对GPS在我国地震监测中的发展进行了展望。
In this paper we firstly review the development of application of GPS technology to earthquake monitoring in China,and then describe mainly GPS application to the following aspects:data processing,time series,velocity field and strain-rate field of the tectonic deformation of the Chinese mainland,quantification of the movement of active blocks in the Chinese mainland,and seismological research.Finally,we discuss the problems and challenges we are currently facing in GPS in earthquake monitoring in China,and put forward prospects from four aspects:earthquake prediction research,basic research,GPS network monitoring layout,and GPS solution accuracy and timeliness.
