摘　　要：总结一种确定刚体板块内稳定台站选取的方法,即首先分析各台站的数据质量,然后利用7参数法进行精选,并对精选台站进行监督分类,最后使台站空间分布均匀化,以此选择GNSS数据处理中的IGS框架点,以建立精确的地球参考框架。The stations constrained on international terrestrial reference frame（ITRF） are usually chosen with some random and uncertainties,which directly affects the precision and reliability of ITRF.A system method to select stations on the rigid plate was summarized.Firstly,analysing the quality of data at each station,the second step is rigorous selection of the stations 7 parameters transformation.The third step is supervision clustering to eliminate some stations that is largely affected by local diastrophism and finally,we make stations well-proportioned spacial distribution.With by using the method,IGS frame station can be chosen in GNSS data processing to establish high precision terrestrial reference frame.
