摘    要:利用时频分析方法(FTAN)测量基阶Rayleigh面波群速度频散资料,在纯路径频散反演时,将方位各向异性计算在内,反演获得中国大陆中东部及海域地区(20°-45°N,110°-130°E)8-200 s共28个周期的Rayleigh面波群速度空间分布图像.研究表明,研究区域Rayleigh面波群速度分布与已有地质构造特征具有较好的相关性.

Abstract:Using an frequency-time analysis method (FTAN) to measure fundamental mode Rayleigh wave group velocity dispersion and taking azimuthal anisotropy into consideration when we performed pure-path dispersion inversion,we obtained 28 group velocity maps from 8 s to 200 s in the centra,eastern Chinese mainland and the seas in eastern China (20°-45°N,110°-130°E).The group velocity maps from different periods indicate that:our group velocity maps agree well with known geological and tectonic features.
Keywords:surface wave  central and eastern chinese mainland  sea  crust and upper mantle  tomography
