摘　　要：为了解决电子政务系统建设中存在的"信息孤岛"问题,提出了一个基于工作流实现服务组合的系统框架。该框架通过流程服务中心的工作流引擎对遗留系统发布的Web服务进行组合,实现了整合遗留系统和跨部门协同办公,从而能够有效地满足业务用户的需求,以及实现对敏捷业务需求的快速响应。最后以跨部门电子政务系统验证了该框架的合理性,结果表明是可行和有效的。To solve the information silo problem in the construction of E-government system, the authors put forward a frame based on workflow technology to implement service composition, which set up a process service center to compose the service of legacy system and implement the integration of legacy system and trans-departmental cooperative work. In this way, it could be suitable for the individual demand and realize quick response for business agility. Finally, a trans-departmental Egovernment system verifies the rationality of that frame, which suggests it is feasible and effective.
