| 摘 要： | 提出将不同GPS网融合为一体的方法，实现中国大陆及周边地区高精度GPS网的融合，获得中国大陆及周边地区ITRF2000水平运动的速度场。在此基础上，得到了中国大陆及周边地区相对于具有整体旋转的欧亚板块的速度场和相对于具有整体旋转和均匀应变的欧亚板块的速度场。分析了中国大陆及周边地区速度场的基本特征，并探讨了该地区水平运动与变形的动力源。 |
| 关 键 词： | GPS 融合 地壳水平运动 动力学分析 中国大陆速度场 |

| Abstract: | In the paper, the combination of high-precision GPS networks has been realised in China's Mainland and its surrounding areas. The horizontal movement velocity field in ITRF2000 in the China's Mainland and its surrounding areas has been obtained. Based on this velocity field,the velocity fields respect to Eurasia Plate with entirety rotation and respect to Eurasia Plate with entirety rotation and even strain have been obtained in China's Mainland and its Surrounding areas. The basic characters of velocity field in Chinese Mainland have been analyzed. The source of the force for the crustal horizontal movement and deformation in the areas have been explored. |
| Keywords: | combination of GPS network velocity field of Chinese Mainland geodynamic analysis |
