地震发生后处于不同地震烈度区域的地物受灾程度不同。快速准确地获取地震影响或波及范围内地震烈度空间分布，是震后应急救援的重要依据和主要参数。依托云计算技术，以云服务方式构建地震烈度速报系统，提供可扩展、可配置、开放透明的地震影响场分析应用服务，将是我国烈度速报系统研究开发与应用中的一项新技术和发展趋势。本文依托研究小组自主研发的地理知识云服务系统GeoKSCloud，以福建省为研究区域，在提出适用于福建省地震烈度衰减关系与地震动峰值加速度场地校正方法的基础上，开展了地震影响场分析云服务系统的设计与实现工作，分析了地震影响场分析云服务的运行机制和服务组合工作流；实现了地震烈度衰减关系计算方法、场地放大因子校正方法、网格点场地类别属性获取、网格点沿地震衰减长短轴方向的坐标变换等相关原子服务的云服务封装，以及支撑数据云存储、网络地理信息系统的云服务门户的开发与集成；最后，以1604年发生在泉州近海7.5级大地震为震例，在云服务门户进行了全省范围内所有等间距网格点地震峰值加速度（基岩PGA和地表PGA）的计算、插值，并进行计算结果与实际调查数据的对比分析。结果表明，因充分考虑了具体场地的放大效应，构建的地震影响场分析云服务，不仅较传统单凭地震烈度衰减关系确定地震动峰值加速度方法更加精细化，而且提供的服务与传统的网络服务相比具有可扩展、可配置、开放透明等明显优势，可为我国烈度速报系统研究与应用提供一个共性技术与支撑服务平台，创新地震烈度速报的运营模式。

After the occurrence of an earthquake, different surface features at different seismic intensity areas are exposed to individual degrees of damage. The quick obtainment of accurate seismic intensities and their spatial distribution is an important basis and parameter for the post-earthquake emergency rescue. To construct seismic intensity rapid reporting system as a cloud service applying cloud computing technology and provide scalable, configurable, transparent seismic influence field analysis application service, will be a new technology and trend for the development of seismic intensity rapid reporting systems. Based on a geographical knowledge cloud ser-vice system, namely GeoKSCloud, which is developed innovatively and independently by our research team, this paper carried out the design and implementation of a cloud service system for seismic influence field analy-sis. By taking Fujian Province as the study area, seismic intensity attenuation relationship and peak ground mo-tion acceleration site correction method suitable for Fujian area are firstly analyzed, and then the working mecha-nism and workflow-based service composition of their cloud service are proposed. To implement the cloud ser-vice, related atomic services are realized, service-oriented packaged and published on GeoKSCloud system (such as seismic intensity attenuation calculation service, PGA site correction service, seismic site property obtaining service for grid points, service for coordinate transformation along the seismic attenuation axis direction for grid points, et al.), data services for supporting spatial datasets are published as well, and also a Web GIS based cloud service portal are developed and integrated with GeoKSCloud. Finally, an analysis case of seismic influence field analysis is carried out on the constructed cloud portal, with the offshore 7.5 earthquake occurred in Quan-zhou area in 1604 as the real case. The peak motion accelerations (including bedrock PGA and ground PGA) for all equally spaced grid points within Fujian Province are calculated via the cloud service proposed. Based on the PGA values of the grid points, the spatial distribution of PGA values covered Fujian Province was also interpolat-ed and further comparative analyzed with the actual survey data. The results show that, the seismic influence field analysis cloud service presented in this paper, which has taken account of the site-specific amplification ef-fecting, can provide more precise seismic influence spatial distribution than the traditional method which consid-er only the seismic intensity attenuation relationship. The cloud service system with distinct advantage features of cloud service, such as scalable, configurable and transparent, would provide a common technology and a sup-port service platform for intensity rapid reporting system research and application, and also give an innovative operation pattern for public service of seismic intensity rapid reporting.
