摘　　要：本文分析了Web Services在空间信息服务的研究现状及存在的问题,提出基于REST风格的Web Services的空间信息服务的架构。具体探讨了基于协议SOAP、WSDL、UDDI的RPC风格Web Service的优缺点,讨论基于纯REST风格的Web Services原理、优势;并在此基础上提出面向资源的空间信息服务的架构和共享模式。This article analyzed the problem and current situation of Web Services in spatial information service. On account of the issue, it brought up Web Services architecture based on the REST style. Concretely, the paper probed the merit and demerit of Web Services of RPC style based on SOAP, WSDL and UDDI protocols, and discussed the principle and advantage of the services based on real REST style.
