摘　　要：SOA的应用日益广泛,构建SOA的工具和平台也日益丰富.而集中式SOA架构会增加成本,限制资源的再利用,降低系统的灵活性,并且有可能导致成本高昂的系统瓶颈.基于服务空间的服务提供模型是一种分布式SOA架构,他通过构建和部署服务空间来分步骤渐进式地实施SOA,并且利用服务空间可以整合已有的系统和资源而提供服务功能,并不需要改变原有系统的运行环境,并且服务空间之间是独立的,不需要一个共有的Hub、Bus或中央服务器.这样不但使得已有(或新的)IT资产可以得到更好重用,而且避免新增加昂贵的服务器和中间件软件,因此,能够更好地满足基于SOA架构的应用程序对各项技术和成本的要求.SOA is broadly applying increasingly, platform and tools which set up SOA also enrich increasingly. But the centralized architecture of SOA will increase cost and limit a resources of again make use of, lower the vivid of system, and probably cause the cost high system bottleneck. The model based services space for provisioning services is a kind of distribute architecture of SOA, it can be divided a step gradually implement SOA by building and deployment service space, and can integrate have already have of system and resources to provide service function by service space, don＇t need to change at existent systematic executing environment, and the of service space be independent, don＇t need a Hub, Bus or central server in common. So not only make have already have（or new of） an IT property to reuse efficiently, and avoid to add an expensive server and the middlewares, therefore can betterly satisfy according to the request of applied procedure to various techniques and the costs of SOA.
