摘　　要：针对地震短临预报面临的科学问题,分析研究了地震前兆(近场前兆、远场前兆和大尺度动态前兆)预报地震的物理基础;总结了地震短临前兆时空演化特征和同步耦合现象。高空技术在地震前兆观测中的应用将有利于短临预报实践与探索。Aiming at main scientific problems existing in earthquake short-term and immine nt prediction at present, the physical basis of seismic precursors (source precu rsor, field precursor, large-scale dynamic precursor) is discussed. The spatio -temporal evolution characteristics and synchronous-coupling phenomena of shor t-term and imminent precursors are summarized. The application of space technol ogy on earthquake precursor monitoring will benefit the exploration and practice of earthquake short-term and imminent prediction.
