通过将山东地区GPS 观测结果与穿透整个岩石圈的SKS 剪切波分裂及近场资料剪切波分裂的快波方向相比较，来探讨山东地区壳幔运动的耦合作用。结果发现，地壳内近场快剪切波偏振与SKS 快剪切波偏振总是相差十几度以上，这种差异可能说明，山东地区壳幔之间构造活动可能有一定程度的解耦，表明山东地区的壳幔运动耦合作用可能既不是壳幔强耦合型，也不是简单的壳幔解耦型，该地区的壳幔运动耦合作用可能是2 种模式共存的不均匀分布或者是物理性质介于两者之间的渐变模式，这与早先对华北地区的类似研究获得的结论相同。

GPS observation comparing with the SKS fast-wave polarization through the crustmantle and seismic anisotropy of the crust was used in this paper to study the coupling relationship between the crustal movement and the mantle deformation． We found that the fast-wave polarization in the crust is always a few degrees above ten with the SKS fast-wave． This difference may show the decoupling of crustal movement and mantle deformation in the Shandong region． The characteristic of Shandong region is that the crust-mantle coupling is not simply crust-mantle decoupling，nor a strong coupling． There may be an uneven distribution caused by two kinds of coexistent modes or a gradual change of physical property between the two modes． The finding is consistent with the previous conclusions by the similar studies of North China．
