| 摘 要： | 运用块体不连续变形分析方法 ,对利用GPS测量数据解算中国大陆及其周边块体的位移进行分析。结果显示 ,除块体 2、10、13为近东西方向的运动 ,块体 15为近北东向的运动外 ,其余块体均朝南东或南东东方向运动。同时 ,各块体还以各自的角速度绕其重心旋转。整个研究区在南北方向是压缩的 ,所得的最大主应力方向与利用震源机制解与原地应力测量的结果总的来说大体一致。最后 ,对产生中国大陆及周边块体运动与变形的动力源进行了讨论

| Abstract: | In this paper, on the basis of DDA theory and results of GPS the author analyzed the movement and deformation of the region in China continent and its ricinity. The result shows that all blocks move southeastwards or southeast east, except block 2?10?13 moving nearly westeastwards and block 15 moving northeastwards. Each block rotates around its centre of gravity. Whole area studied was compressed in the direction of southnorthern. This result is nearly equal to that outcomes from stress observation and focal mechanism solution. Finally, the auther disscussed the dynamic source causing movement and deformation in this researched region. |
