摘要
Selecting the data from early 1999 to Apr., 2010 recorded by the continuous observational stations of the project of China Crust Movement Measuring Network, the authors analyze 80 GPS baselines time series in Chinese mainland. Then the authors discuss the tendency variation of all these baselines in normal condition and summarize the abnormal changes of GPS baseline time series before 2001, West Kunlun Mountain Pass Ms8.1 earthquake and Wenchuan, Ms8.0 earthquake. On this basis, the authors analyze the recent variation of GPS baseline time series.
