如何有效地进行高速客运专线的景观设计与评价，尤其是预评价，是一个重要的研究课题。探讨了利用VR（虚拟现实）技术对高速铁路景观设计进行综合评价的可行性和必要性。针对高速铁路景观设计的主要对象--线路及附属设施，首先研究了其营造方法。在对高铁沿着虚拟景观要素进行综合分析的基础上，建立了高铁沿线景观沿着层次结构，并建立了高铁沿线附属设施模型库。并以标准数据格式OpenFlight数据库为工具，实现了三维轨道模型的智能化生成方法。然后，通过OpenFlight API的编程接口，利用OpenFlight和External References以及运行模型数据文件，完成了辅助设施环境的生成。
It is an important research topic to do the landscape design and evaluation, especially the pre-assessment, of high-speed passenger dedicated rail line effectively. This paper discusses the feasibility and necessity of using VR (virtual reality) technology to evaluate the high-speed railway landscape design comprehensively. For the rail line and ancillary facilities being the primary target of landscape design for high-speed railway, the building methods of them are studied in the first place. Based on an integrated analysis of the virtual landscape elements along high-speed rail line, a hierarchical structure of the landscape along the line is built, and a model database of ancillary facilities is established. Furthermore, with OpenFlight database, a standard data formats as a tool, the intelligent generation method of 3D rail track model is achieved. Then, using the Instances and External References and operating model data files through OpenFlight API's programming interface, the generation of ancillary facilities environment is accomplished.
