摘　　要：利用对全球约 2 0年的天体测量和测地VLBI资料归算所给出的 12 7台站的坐标和速度场 ,分析确定了欧亚板块的板内形变。结果比较表明 ,上海VLBI站相对于欧亚板块稳定区域的运动约为东向 1cm a。但作为中国大陆现代地壳运动测量的基准站 ,其运动参数尚需进一步精化。From the reduction of about 20 years globally distributed astrometric and geodetic VLBI observations, the coordinates and velocity field of 127 stations were resulted. The intra-plate deformation of Eurasia was determined accordingly. Comparisons of results from various authors show that the relative motion of Shanghai VLBI station to Eurasia plate is eastward about 1cm/a. As the fiducial station in the measurement of the temporary crustal motion of China continent, the motion parameters of Shanghai station is still requiring improvement in precision.
