| 摘 要： | 用２４９６个中国数字地震台网（ＣＤＳＮ）和世界数字地震台网（ＧＳＮ）的长周期面波群速度资料，反演得到中国及邻区的不同周期的群速度分布图以及１１４４条纯路径频散曲线。它反映了中国及邻区横向和纵向均存在着明显的非均匀性。周期为３０ｓ的群速度分布图反映了地表的板块构造。

| Abstract: | Rayleigh wave group velocity variations in periods of 8 s and 400 s in China and the neighboring areas and 1144 pure path dispersion curves are obtained by using 2496 long period seismic waveforms recorded by CDSN and GSN. The results show horizontal and vertical anisotropy in China and the neighboring areas. Rayleigh wave group velocity variations in periods of 30 s are correlated with continental plate tectonics. |
