摘　　要：为满足新一代信息化战争中集成陆、海、空、天、电等全方位、多军种信息,建立协同作战网络及一体化战场环境的需求,提出了面向军事信息网格(MIG,military information grid)的信息集成与服务框架.该框架纵向分为资源层、基础网格平台服务层、元数据服务层、应用服务层、用户层,其中应用服务层按服务内容的不同横向又分为数据、信息、知识服务3层结构.阐明了元数据服务在框架中的核心位置及作用,分析了框架实现的若干关键技术,对我国MIG建设中信息集成与服务技术方案有一定参考作用.A service framework in military information grid （MIG） is proposed to integrate various battlefield information and the coordinated combat network is built. The framework can locate the required data in hundreds of geographically distributed sites. Vertically, it is composed of resources layer, grid-based service layer, metadata service layer, application service layer, and also user management layer. Meanwhile, the application service layer is horizontally partitioned into data service layer, information service layer, and knowledge service layer depending on the types of different service contents. The crucial functionality of metadata in the framework is demonstrated, and several related key techniques in the implementation are discussed. The framework is verified by the simulation in similar telecom scenarios based on service-oriented architecture. And it could be a feasible reference to meet the information sharing requirements of MIG.
