摘　　要：线性参照模型是以线性参考系统为基础,以动态分段技术为核心的一维空间数据模型。本文针对铁路空间数据的一维线性分布特征与铁路部门以一维线路为主体的运维管理模式,探讨了铁路空间数据的线性建模方法,利用空间数据库技术实现铁路空间数据、属性数据及业务数据的一维线性存储与管理,并提出了基于一套多尺度线性参照模型的铁路空间数据库的设计方案。试验表明,该方案能够为全路提供一套统一的一维管理基准,在动态数据管理、数据更新和共享等方面具有较大优势。Linear referencing model which takes dynamic segmentation technique as the core is a one-dimensional spatial data model based on linear referencing system. Taking the one-dimensional linear spatial distribution of railway spatial data and the opera- tion and maintenance management pattern of the railway department into account, this paper explored the linear modeling method for railway spatial data, applied spatial database technology to the realize the one-dimensional storage and management for railway spatial data, attributed data and business data, and proposed the design scheme of railway spatial database based on a series of multi-scale lin- ear referencing model. The experimental result showed that the scheme would provide a series of unified one-dimensional management benchmark for the whole railway system with advantages in dynamic data management, data updating, data sharing, etc.
