中国大陆被认为是研究大陆地壳运动和动力学的最理想地区．过去基于地面观测技术，很难对时间尺度为数年的大空间范围的陆内块体运动作定量研究．本文根据中国国家攀登计划“现代地壳运动和地球动力学”１９９４～１９９６年ＧＰＳ全国复测数据，提出了一种完全基于实测资料，通过卡尔丹角计算块体间现时运动欧拉矢量的理论方法．尝试性地初步建立了刻划中国大陆西藏、川滇、甘青、新疆、华南、华北和黑龙江等７个主要块体现时运动模型ＰＢＭＣ－１（ｐｒｅｓｅｎｔ－ｔｉｍｅｂｌｏｃｋｓｍｏｖｅｍｅｎｔｍｏｄｅｌｏｎｔｈｅＣｈｉｎｅｓｅｃｏｎｔｉｎｅｎｔ），首次在数年时间尺度内给出了中国大陆块体相对运动的点位速度场及边界带运动．模型结果表明：各块体的运动速率由南向北、由西向东逐次减少；运动方向由北北东逐步转向东以致东南和东东南．印度板块的碰撞对中国大陆内部诸块体运动起主导作用；而诸块体运动又决定着块体边界带断裂带的活动方式与速率．模型给出的数年尺度的现时运动，总体上与地质学给出的百万年以来的平均状态相似，与地球物理学和天文学观测结果也较符合．ＧＰＳ等空间测地结果已初步具备揭示正在进行中的地壳运动的能力 China is considered to be the best area for studying continental crustal movement and dynamics. In the past, based on ground-based observational techniques, it was difficult to quantitatively study intracontinental block motion over a large space scale with a time scale of several years. Based on the national re-measurement data from 1994 to 1996 of the National Climbing Project “Modern Crustal Movement and Geodynamics”, this paper presents a theoretical method based on the measured data to calculate the Euler vector of the current motion between blocks based on the Cardanian angle . Tentatively tentatively established the PBMC-1 (present-timeblocksmovement modellontheChinesecontinent), which depicts the seven major blocks of Tibet, Sichuan, Yunnan, Gansu, Xinjiang, South China, North China and Heilongjiang in mainland China for the first time on a multi-year time scale The velocity field of the point and the movement of the boundary zone are given for the relative movement of blocks in China. The results of the model show that the movement rate of each block decreases from south to north and from west to east successively; and the movement direction gradually changes from north to east to east and to the east and southeast. The collision of Indian plate plays a leading role in the movement of various blocks in mainland China, and the movement of blocks determines the mode and rate of activity of the boundary zone in the block. The present-day movement of the model at the multi-year scale is generally similar to that given by geology in millions of years and more in line with the results of geophysical and astronomical observations. Geodetic GPS results have initially shown the capability to reveal the ongoing crustal movement
