By using all 103 days GPS data of IGS in china, from year 2000 to 2005, the baseline is solved with GSMIT software. With One day's baseline solution as the input data, based on the mathematical floating model of station, the floating velocity of station is solved and the crustal movement is gotten; then, according to Euler theorem of plate movement, the Euler vectors of Chinese mainland is obtained; furthermore, the floating velocity of the station area in Eurasian plate is acquired. The results show that, in ITRF2000 framework, the station floating velocity is similar with what announced by IGS and so does the Euler vector, which shows that the continental shelf of China has an accelerated tendency to eastward movement.
