摘　　要：结合多层软件架构技术,提出一种通用的多层次城镇土地定级估价系统体系框架,并以Arcgis Engine技术为核心,使用Java语言实现了城镇土地定级估价系统。讨论了系统构建过程中因素因子体系表、单元格划分等关键问题,为同类系统的开发提供了一套通用性强,开发成本低,易于维护和扩展的土地定级估价解决方案。A method of multiple-tiers architecture is provided to establish a framework for the system of decide-grade and appraisement for urban land. It consists of six layers： UIL （User Interface Layer）, DAFL （decide-grade and appraisement facade layer）, DARL （decide-grade and appraisement rule layer）, DAL （data access layer）, DEL （data entity layer）, and AFL （application framework layer）. This layers are all introduced in detail and succeed in building the system of Decide-grade and appraisement for urban land based on AE （arcgis engine） with Java. And in the process of system building, a series of correlative problems is resolved with XML and vector-raster mix technology. A good solution is given, which is low cost, easy to maintain and extend, for decide-grade and Appraisement for Urban Land.
