摘　　要：作为空间信息基础设施,空间数据库的建设效率和质量决定了地学信息项目的成败。目前空间数据库建库大多与特定GIS平台相关,建库过程繁杂、效率低下。为了适应复杂多变的建库需求,通过分析空间数据库数据模型的结构化表达,研究并提出利用数据字典存储数据模型,自动化建库的技术方法。多个项目实践验证该方法能够显著降低建库复杂性,提高建库效率,具有一定的通用性。Spatial database is a spatial information infrastructure, and the efficiency and quality of its construction determine the success or failure of the geo - information project. Currently, the spatial database is mostly associated with a specific GIS platform. The database construction process is complex, inefficient and lack of versatility. In order to adapt the database construction to complex variability, the authors, through an analysis of the structural expression of the spatial database data model, studied and put forward the method for storing data model by using data dictionary and the technology for automatic construction of a spatial database. Practice of quite a few projects has proved that the method can significantly reduce the complexity of building a database and improve efficiency, together with certain extent of versatility.
