摘　　要：从大地震速报的科学意义和社会意义出发,论述了我国地震速报的现状,回顾大震速报的发展历程。以此为基础,讨论国家数字地震台网目前大震速报的模式,分析了在数字化代替模拟以后使用速度震级的可行性,以及量取20秒周期面波震级的必要性。从地震科研的发展方向构想我国未来地震速报的基本模式。The present situation of the quick report of earthquake (QRE) in our country is analysed from the view point of both science and society,and the remembrance of the QRE development history is made.On the basis of this,the feasibility that the velocity magnitude might be adopted after digitalization replaces analogy,and the necessity that the surface-wave magnitude is determined at the 20-second period are discussed.A preprimary model of the QRE in our future is proposed according to the develop direction of earthquake research.
