摘　　要：主要阐述利用空间大地测量测定和研究板块运动的研究成果及最新进展 ,并与地质学方法进行了比较 ,结果表明空间大地测量方法测定板块运动由单一手段发展为多种手段的综合 ,最新的研究是利用ITRF96 、ITRF97地球参考架的站坐标及速率建立新的板块运动模型 ,这些模型和相同时期的地质模型 ,整体上一致但仍存在着差异。对于太平洋板块所有大地测量测定的运动速率均大于地质学模型 ,极位置的经度也有系统偏差。The research results and the latest progresses in measurement of plate movement by space geodesy and the comparison with the results by geological method are expounded.It is shown that the measurement of plate movement by space geodesy has developed from by single kind of technique to by the synthesis of multiple techniques. The latest research is carried out by means of the results of Earth reference frame,e.g.ITRF 96 ,ITRF 97 , to build new models of plate movement.These models and the models built by geological method in the same period agree with each other very well as a whole while for some plates there are considerable differences.Among them,for the Pacific plate all of the moving rates measured by geodetic method are larger than that in the geological models,and the longitude of the polar position has some systematic deviation.
