摘　　要：为了更好地实现地籍和房产要素数据的互操作 ,探讨了房产空间要素的 GML 模型及其应用 ,并首先分析了房产要素的类型和要素之间的相互关系 ,同时从精简存储、提高效率的角度出发 ,提出了标准单元的概念 ,用来描述房产要素模型 ;然后 ,基于 GML 语言设计了房产空间要素的 XML 模式 ,并以此定义和描述了房产要素及其属性 ;最后利用 Java语言开发了房产管理信息系统 ,实现了房产权籍要素图形和属性的一体化管理。实际应用表明 。Descriptive models of housing spatial features based on Geographic Markup Language (GML) and its application are presented in this paper. The types and relationships between housing spatial features are firstly analyzed, and a new model for describing housing features is then proposed using the concept of standard cell from the point of reducing storage redundancies and improving query efficiency. Base on this, housing spatial features description and relationships between them based on GML are further put forward. These housing spatial feature models are defined as NatureStoreyModel, LogicalStoreyModel StandardCellModel, CellModel and LineModel, and the relationships are defined as natureStoreyMember, logicalStoreyMember, standardCellMember and lineMember. A schema defining the GML structure is given, incorporating both the geometry and attribute of housing features. And an application system used to manage housing information is developed based on Java, document object model (DOM) and simple application interface for XML (SAX). The implementation of the proposed models is tested through the system and the results approve the capability of the models.
