摘要
空间大地测量以高精度、高时空分辨率测定地球整体 (地球自转 )和各圈层 (特别是大气、海洋与地壳 )的运动 ,使地球动态变化的监测、研究及应用呈现了崭新的面貌。本文介绍了近年来国际地球动力学最新发展概况 ,内容包括地壳运动、地球自转、重力场时间变化等。
Space Geodesy, measuring the movement of the whole earth(rotation of the earth) and each of its spheres(especially the atmosphere,ocean and crust)with high accuracy and high spatio temporal resolution,hascontributed significantly to the progress of dynamic monitoring,research and application of the earth changes.The latest international development of geodynamics in recent years is introduced in this article,including crustal movement,rotation of the earth, time change of gravity field, and sea level change, etc.
