| 摘 要： | 根据活断层资料,利用贝塞尔双三次样条模型对中国大陆及其邻区晚更新世以来的平均水平应变率场进行了计算。结果显示,中国大陆的构造膨胀率、构造剪切应变率、构造矩率和旋转角速度的分布都与地震的分布相似,呈条带状,并与活动地块的边界和主要断裂位置一致。另外,中国大陆的地壳变形具有西强东弱的整体特征。

| Abstract: | Using active fault movement data,we calculated the average horizontal strain rate field of China Continent and vicinity since late Pleistocene with Bessel bicubic spline model.The results show that the distribution of the tectonic dilatational strain rate,shear strain rate,tectonic moment rate and rotation rate of China Continent are consistent with that of the earthquake,appearing in the shape of band,and consistent with the locations of active block boundaries and main faults.In addition,the crustal deformation of China Continent is of a whole feature "strong in the west but weak in the east". |
