在虚拟地理空间中开展复杂科学实验和管理分析，是目前及未来发展的一个重要趋势。本文对高速铁路场景中的线路、地物和地形对象的关系进行了详细分析，提出了基于空间关系描述的虚拟高速铁路场景建模方法。通过XML标记语言对线路、地物和地形的空间关系进行统一描述，引导和规范场景建模过程中的模型点位计算和地形处理过程。详细讨论了虚拟高速铁路的场景建模流程、场景对象空间关系定义、模型点位计算方法以及地形处理方法，并选择案例区域进行试验。试验结果表明该方法能够有效地理清虚拟场景中各种对象间的关系，从而可以快速建设符合现实标准的、具有高度仿真感觉的虚拟高速铁路场景。

It is an important trend to carry out complex scientific experiments and management analysis in a virtual geographic space. This paper analyzed the relationship among the high-speed railway scene routes, constructions and terrain in detail, and then proposed a virtual high-speed railway scene modeling method based on spatial relationship constraint. The XML markup language was used to describe the spatial relationships among the railway routes, terrain and constructions, which were used to limit and guide the model points calculation and terrain processing in scene modeling progress. The virtual high-speed railway scene modeling process and some key technologies such as the definition method of the scene objects spatial relationship, model points calculation method and terrain processing method were discussed in detail, and a case study region was selected for carrying out a test. The results show that these methods can clarify the virtual scene relationships among various objects effectively, and can rapidly construct virtual speed railway scenes which meets the realistic standards.
