| 摘 要： | 本文根据中国地壳运动观测网络基准站1999年初至2010年9月底的资料,对中国大陆90条GPS基线时间序列进行了分析,讨论了这些基线在正常情况下的趋势性运动特征,总结了2001年昆仑山口西和2008年汶川两次8级大震前GPS基线时间序列的异常变化,并在此基础上分析了GPS基线近期变化情况。

| Abstract: | Using the data of early 1999 to September,2010 from continuous stations of the Project of China Crust Movement Measuring Network,this paper analyzes 90 GPS baseline time series of continuous stations in the mainland of China.Firstly,we discussed the tendency variation characteristics of all these baselines under the normal condition,and then summarized the abnormal changes of GPS baseline time series before two strong earthquakes.Finally,recent variations of GPS baseline time series have been analyzed. |
