摘　　要：针对目前空间信息Web服务组件的访问调用效率等问题,在传统空间信息Web服务模型的基础上引入Ajax技术,提出一种新的集成Ajax引擎的空间信息Web服务模型和集成服务框架.分析了服务框架的集成应用关键在于空间信息服务封装包、Ajax引擎请求/响应对象的设计以及异步调用服务协作机制.以异步方式响应服务交互,实现空间信息服务的异步调用,提高了空间Web服务设计和服务调用的效率,并将此集成服务框架应用于区域科技信息共享平台.In view of the lower efficiency of the design and call for geospatial Web service component, this paper presented one new service model and integration framework of geospatial information Web services, which based on the classic Web service model integrated to the new Web application technology-Ajax, which combined with Ajax engine. The basic approach and principle to development the new integration framework of Ajax engine were how to design the geospatial Web service component and the object packager of Ajax engine and the cooperation mechanism of non synchronous model of Web service. The basic function and the Web service caller based on SOAP protocol was designed and brought to success. And then the design efficiency of the geospatial Web services component was improved. In the mean time, the call efficiency was also improved. Finally, it brought to success to construct that the regional integrated scientific information sharing network combined with this new integration framework.
