为了能直观、形象和动态地反映不同区域税收状况的空间分布规律和变化趋势,提高异构税收征管GIS系统的数据共享和互操作性能,采用GIS企业级中间件与开放地理信息联盟(OGC)规范的GIS Web服务(GIServices)相互集成的方式,构建一种面向服务架构(SOA)的税收征管WebGIS系统(STAXGIS)。STAXGIS是一致性的业务模型和信息模型,通过GIS企业级中间件提供空间数据转换、税收业务处理与税收空间分析等高级服务功能,并采用GIServices提供税源查询与定位、税收专题分析、税务查询与申报等方面的信息服务。STAXGIS采用J2EE 4层框架(即数据层、应用服务层、Web服务层和客户层)实现其部署与分层管理,这与传统税收征管GIS系统相比,STAXGIS的征管效率和可扩展性大大提高。以福建省福州市为例的研究表明,STAXGIS可增强现有分散管理的异构税收征管GIS系统在分布式环境下的信息共享能力和互操作性,提高异构环境下税收征管空间分析的整体效率,并向各级税务管理部门提供直接或间接的决策支持。
In order to reflect the spatial distribution rules and trends of the taxation status in different regions intuitively, iconically and dynamically, improve the capability of data sharing and interoperability of the heterogeneous tax administration GIS systems, a tax administration WebGIS system based on Service Oriented Architecture (SOA) is constructed by the integration of the GIS enterprise-level middleware and GIS Web services (GIServices) on account of the specifications of Open Geospatial Consortium (OGC). STAXGIS is based on the consistent business model and information model. The GIS enterprise-level middleware can provide spatial data conversion, taxation business processing, taxation spatial analysis and other advanced service functions, meanwhile the GISservices can provide information services (such as query and location of tax sources, tax thematic analysis, taxation queries and declaring and so on). The four-layer framework of J2EE which contains the data layer, application service layer, Web service layer and client layer is used for the hierarchical management and deployment of the STAXGIS. Compared with the traditional tax administration GIS systems, the administration efficiency and scalability of the STAXGIS is greatly improved. The research which takes Fuzhou City in Fujian Province as an example has shown that STAXGIS could strengthen the capabilities of information sharing and interoperability of the decentralized heterogeneous tax administration GIS platform in the distributed environment currently, and improve the overall efficiency of spatial analysis for tax administration in heterogeneous environment. It can also provide the tax administration departments at different levels with decision support directly or indirectly.
