摘　　要：地震预警信息服务策略是减轻地震灾害损失的关键手段。从预警信息的接收策略、发布策略、响应策略以及策略的具体设置等方面展开探讨。对于预警信息的接收策略,就发布系统高效、准确地接收上游融合系统推送的地震预警信息进行分析;针对信息发布策略,探讨策略阈值过高和过低的设定问题,以确保信息发布的准确性和有效性,介绍了终端设备的响应策略和信息更新原则;借鉴美国、日本等国家的先进经验,结合天津市本地实际情况,制定符合本地需求的地震预警信息发布及响应策略。该策略不仅能够满足天津及周边地区有感地震的预警信息发布需求,还能有效应对远场大震的信息发布。通过有效实施以上策略,能够显著提升地震预警信息服务的实效性,为减轻地震灾害损失提供有力支持。Earthquake early-warning information services are crucial for mitigating the losses caused by earthquake disasters.This discussion explores four aspects:the reception strategy for warning information,the publication strategy,the response strategy,and the specific settings of these strategies.It analyzes the reception strategy for the earthquake early warning information pushed by upstream integrated systems within the publishing system.Regarding the information publication strategy,it addresses the issues of thresholds being set too high or too low to ensure the accuracy and effectiveness of the information released.The response strategies of terminal devices and principles for information updates are also introduced.Finally,drawing on experiences from countries like the United States and Japan,the strategies for publication and response are tailored to the local context of Tianjin.These strategies are designed to meet the early warning information needs for perceptible earthquakes in Tianjin and surrounding areas,as well as the requirements for issuing alerts for distant major earthquakes.By effectively implementing these strategies,the efficacy of earthquake early warning information services can be enhanced,providing strong support for reducing the losses from earthquake disasters.
