摘　　要：全球和区域地震波衰减模型揭示了地球内部滞弹性的非均匀结构,为解释地球内部温度、熔体和挥发分分布、分析地球动力学过程和地震震源机制等提供了新的启示.近年来,地震学衰减层析成像在面波及背景噪声衰减成像、体波衰减成像、区域震相及尾波衰减成像、全波形衰减成像的理论与应用方面均取得了实质性进展.在此基础上本文列举了一些地震学衰减层析成像研究中正在开拓和发展的方向.Global and regional seismic attenuation models reveal anelastic heterogeneous structures in the earth, which shed new light on the temperature, melt and volatile fraction of Earth’s interior, as well as the geodynamic processes and source focal mechanisms. In recent years, substantial progresses have been made in the theory and applications of attenuation tomography, including surface-wave and ambient-noise attenuation tomography,body-wave attenuation tomography, regional-phase and coda-wave attenuation tomography, and full-wave attenuation tomography. Based on this review, we list the points to be solved and the development prospect of seismic attenuation tomography in the future.
