| 摘要: |
| 本文首先从地震预警的概念、系统构成和技术方法等方面入手，对目前国际上地震预警技术的最新研究进展和热点问题进行了全面的论述。继而通过对国内发展现状的系统分析，认为地震预警系统的开展在政府、社会、台网建设和研究基础等方面都已经具备了基本的条件。结合当前国内的实际情况，对地震预警系统在实施过程中可能遇到的技术问题和非技术性挑战进行了估计，并建议加强法律措施、公众教育、震害防御等方面的配套工作，最大限度地发挥地震预警系统在防震减灾工作中的作用。 |

| Abstract: |
| Earthquake Early Warning ( EEW) comes into the sight of people as a result of unreliability of earthquake prediction． The paper illustrates comprehensively the research status and hot issues of EEW in terms of the concepts，compositions and methods． The study of the government status，social needs，network building and research foundations reveals that it is a right time to build EEW in Chinese Mainland． It also estimates the technical difficulties and nontechnical challenges in the course of the implementation of EEW in China，and suggests the enhancement of legal measures，public education and seismic protections to bring the Earthquake Early Warning system into full play in earthquake relief． |
