本文利用时频分析方法（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，反演获得了中国大陆中东部及海域地区（110°E-130°E，20°N-45°N）8～200s共28个周期的Rayleigh面波群速度空间分布图像。不同周期的群速度分布图像表明，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。

 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 8s to 200s in the Central、Eastern Chinese mainland and the seas in eastern China(110°E-130°E,20°N-45°N). The group velocity maps from different periods indicate that: our group velocity maps agree well with known geological and tectonic features.
