摘　　要：以县级国土资源"一张图"平台建设为契机,针对县级数据业务支撑能力较弱、数据共享隔阂、信息系统应用局限等问题,提出以SOA搭建面向服务的体系结构,以WCF搭建分布式通信框架,完成"一张图"核心数据服务中心建设。数据服务实现了跨平台的数据传输,达到国土资源"一张图"C/S架构和B/S架构平台的双重支撑。在消息传输过程中,点到点的通信保证了数据的安全同时保证数据传输的安全。在服务请求消息传输前进行了消息压缩,保证了数据的传输效率。此设计方案快速实现了国土资源部门统一的数据管理和透明的数据访问,建设基于数据服务的县级国土资源"一张图"综合管理系统。With the development of information system construction,land and resource management department is making rapid progress on data management and application system. Since data services on the county-level come up against a series of problems,for example,their weak technical supporting system,obstructed internal and external information communication,and many limitations within the applications. In this study,we constructed the core information service platform of ＂ One Map ＂ on the base of service-oriented architecture（ SOA） and windows communication foundation（ WCF）,in order to achieve uniform data management and transparent access. Data servers supported cross platform between C/S and B/S. Moreover,point-to-point communications ensure the safety of data transferring. Message compressions ensured the speed of data transferring. Our approach has rapidly consolidated data management and transparent data access for land and resources,as well as the construction of ＂ one map＂ integrated management system for county-level land resources based on data service.
