摘　　要：针对目前的服务组合模型网络通信代价较高的问题,提出一种多层结构的服务组合模型-STBM(Spanning Tree Based Model).STBM分为服务注册层、虚拟服务层和服务提供层三个抽象层次,每个层次提供正交的功能共同为客户端构造一个服务组合平台.服务注册层起到分布式服务注册与索引的作用;虚拟服务层按服务的功能关系组织成不同的生成树,生成树间依据服务的组合关系构成服务虚拟组合网(Services Virtue Composition Networks,SVCN).分析表明,在达到同样服务组合效果的情况下,STBM的平均网络通信流量比Spidernet有很大的降低.Since there are considerable network communication cost in the service composition model presently. A new multi-layer structure model called STBM（Spanning Tree Based Model） has been proposed in this paper. STBM includes three abstract layers,the service registration layer,the virtual service layer and the service supply layer. The service composition platform can be constructed for the clients with the orthogonal function supplied collectively by each layer. Firstly,the service registration layer is to register the distributed service and index; Secondly,the SVCN（Services Virtue Composition Networks） can be constructed by the service composition relationships of different spanning trees ,which is structured with the functional relationships of the virtual service layer. STBM,with the same service composition effect,has the lower average network communication stream than Spidernet dramatically by the theoretical analysis.
