摘　　要：从地质数据的不断完善到空间大地测量数据的广泛应用,现今板块运动模型的发展有了质的飞跃。评述了其现状与发展趋势;利用ITRF2005的速度场建立了一个完全基于现代空间大地测量实测结果的现今全球板块运动模型ITRF2005VEL,并与地质模型NNR-NUVEL1A进行了比较。结果表明,从整体上看ITRF2005VEL与NNR-NUVEL1A模型有较好的一致性,且较以往的ITRF序列的模型精度更高,但同时也存在着一定的差异性,这与观测台站、板块本身等相关因素都有关。From geological data being continuously completed to spatial geodetic data being widely applied,current plate motion model had progressed greatly,whose actuality and developing tendency had been commented.A new present-day global plate motion model ITRF2005VEL was determinated based on the ITRF2005 velocity field,and was compared with the geological model of NNR-NUVEL1A and the old plate motion models founded on the series of ITRF.The result showed that there is a better consistency of ITRF2005VEL and NNR-NUVEL1A model in whole,and its precision is higher than that of the model of fore-ITRF.While,at the same time,there exists some differences which are related to the factors of observing sites,plates and so on.
