摘　　要：在Web上建立空间信息系统,日益成为Internet的焦点。文中提出的基于多 Agent的多服务源协作模型Multi-SAC,是为了解决 Web环境下,多客户链接,多服务源启动,多Agent协作而设计的分布式体系。它使用空间对象模型SOM建立系统,更侧重于地理空间和逻辑空间的结合,从空间关系的角度集成结构化和半结构化数据。MultiSAC体系具有透明分布,可扩展性好,接口智能等特点。最后探讨了实现一个AM/FM/GIS系统。Spatial Information System on web is attractive increasingly with evolution of InternetThis paper proposes a Multiserver Collaboration Model based on MultiAgent-MultiSAC,which can solve the collaboration problem among the concurrent client,the multiserver and the multiagent.SOM (spatial object model),which emphasizes particularly on the combination geography space with logic space and integrates the structured and semi -structured data according to spatial relation,is used to design this architecture.MultiSAC is a distributed architecture,it has many virtues,such as transparent location,good expansibility and intelligent interface.At last,a concrete AM/FM/GIS system is discussed
