摘要: 城市小区是城市人居环境的重要构成部分,与城市居民生活关系密切。面向城市小区环境综合分析模拟的需求,本文结合虚拟地理环境中虚拟场景和集成建模等概念,设计了可支撑分析模拟的城市小区场景数据组织方法。通过小区系统、小区系统要素和小区系统要素关系来对复杂小区环境信息进行对象化的描述,并按照层次化结构实现城市小区建模场景的组织。利用统一数据表达与交换模型UDX对小区系统-要素-关系中的数据内容进行统一的表达和存储,在此基础上设计了城市小区建模场景对象;利用可扩展接口的方式,实现从城市小区建模场景中抽取符合分析模型需求的数据内容,由此支撑将不同地理分析模型与城市小区建模场景集成。试验结果表明,本文所设计的方法能够有效组织多源异构的城市小区环境数据,并可以便捷地为不同研究方向的城市小区分析模型提供所需建模数据。

Abstract: Urban residential regions are important parts of the urban living environment,and they are closely related to urban life.In order to meet the demands of comprehensive analysis and simulation of urban environments,this paper combines the concept of virtual scene and integrated modeling in the virtual geographic environment (VGE)to design a data organization method for constructing urban residential region for modeling.Through the abstraction of system,object and relation,the complex environment information of an urban residential region can be described and organized in a hierarchical structure.In addition,the universal data description and eXchange model (UDX)was also employed to describe and store the data content for urban residential regions in a uniform manner.The data content that meets the demands of a geo-analysis model can be extracted from the modeling scene,thus supporting the integration of different geo-analysis models and the modeling scene.The experimental results show that the proposed method can effectively organize the heterogeneous urban environment data and provide the demanded modeling data conveniently for the geo-analysis models from different research areas.

Key words: urban residential region, geo-analysis and simulation, modeling scene, virtual geographic environments
