摘　　要：介绍了基于层次细节技术的铁路网信息显示系统的实现方法,重点讨论了显示铁路网上所有中间站的方法,用任意多边形区域选择多个支点、非支点站的方法和查询两支点站集合之间所有流量信息的方法。在实践的基础上,探讨了此技术在全国铁路网编组计划计算机自动编制项目上的应用,并展示了根据此方法编制的软件实际生成的计算机效果图。最后对软件开发实践中的经验和体会进行了总结。It was introduced the practical method of the Railway Network Information Display System based on LODtechnique and discussed the method of choosing multi-pivots and non-pivot stations with any polygon fields and the way toinquire all the volumes information between two pivot concourses. Based on the practice, the application in the auto-authorized the national railway plans of organizing into groups on railway network by computers was discussed. According tothis method, the effect pictures on computer produced by the software were developed. A conclusion of the experienceachieved from the course of software development practice was given.
