摘　　要：为解决企业分布式多源异构地理空间数据互操作的瓶颈问题,设计了基于Web Services的四层多源异构空间信息集成框架。利用Web Services技术,OGC地理信息服务实现规范,和W3C标准的可缩放矢量图形成像模型(SVG)的集成,通过构建空间数据转换服务集成器,在用户和服务之间提供一种透明的松耦合,跨越系统底层的异构性,进行异构空间数据的互操作和显示,从而实现了多源异构地理空间信息集成与共享。在国家地震网络计算应用系统(SECAS)建设中,基于以上框架采用.NET平台进行设计并得到了初步应用。To deal with the bottle-neck of enterprise distributed multi-source heterogeneous geographic spatial data＇s interoperating, the four-tier integration framework of multi-source heterogeneous spatial information based on web services is designed. Through the integration of web services technology, the geographical information service criterion of OGC and the scalable vector graphics model （SVG） of W3C, the integrated device of spatial data translating services is constructed, which can realize the heterogeneous spatial data＇s interoperating and showing by spanning the system＇s heterogeneous and providing a kind of transparent loosely coupling rela- tion between the users and the servers, lastly multi-source heterogeneous geographic spatial information can be integrated and shared. It is primarily designed and applied in the State Earthquake Computing Application System （SECAS） based on the above framework and .NET platform.
