利用中国地壳运动观测网络研究中国大陆相对于ITRF97板块模型形变

THE INVESTIGATIONS ON CRUSTAL DEFORMATION IN CHINA UNDER ITRF97 PLATE MODEL USING DATA OF CRUSTAL MOVEMENT OBSERVATION NETWORK IN CHINA

在建立全球ITRF97板块运动模型的基础上 ,利用“中国地壳运动观测网络”79个GPS基本站的数据 ,建立我国新的地壳运动方向图和块体运动模型 .通过与NNR NUVEL1A地质模型比较认为 ,ITRF97板块运动模型反映了现今十几年跨度的地壳运动 ,在研究我国现今几年到十几年时间跨度的地壳形变时 。

After setting up the global plate motion models based on the International Terrestrial Reference Frame ITRF97, we establish the latest sub plate models in China using velocity fields of 79 GPS base network on the basis Crustal Movement Observation Network of China. In comparision with NNR NUVEL1A geological model, our model presents the present time crustal deformation at the span of years. As the background velocity field, the Eurasia model based on the ITRF97 velocity fields is recommended to investigate present time tectonic deformation in China rather than NNR NUVEL1A.
