摘　　要：利用中国东北地区1998～2005年的GPS数据,结合俄罗斯、韩国和蒙古的部分GPS观测资料,用加权最小二乘方法以迭代的方式解算了阿穆尔板块相对欧亚板块的欧拉运动矢量。最终的33个测站的位移速率加权均方根残差(WRMS)为0.98mm/a。计算结果表明阿穆尔相对欧亚板块运动的欧拉极位于阿穆尔板块的北部边界外兴安岭东端(54.06±1.13°N,135.87±7.16°E),欧拉旋转量为0.099±0.00735°/Ma。The Euler movement constrained by the velocities of the GPS sites across the northeast China, Southeast Russia, Korea and eastern Mongolia of Amurian microplate related to the stable interior of Eurasia is derived with the weighted least square method and an iteration procedure. The weighted RMS of velocity adjustments for the final 33 stations is 0.98 mm/a. The motion of the four regions is consistent with a rigid-body rotation of 0. 099 ±0. 007 35°/Ma, with the pole at 54.06 ±1.13°N, 135.87 ±7.16°E, in the eastern terminal of Stanovoy range which is the north boundary of the Amurian plate.
