摘　　要： 空间数据库的建设速度和成本是影响GIS应用的重要因素。目前空间数据建库存在软件通用性差、建库过程操作复杂、人工干预多、建库效率低等问题。本文针对建库中存在的问题，研究并提出了基于可视化建模思想的空间数据库自动化建库技术，有助于大幅度降低建库复杂性及建库成本，提高效率。 Speed and cost are the two key elements considered when Building a spatial database for a GIS application. At present, there are many problems when building a spatial database, such as lack of a general tool, complex operation, much manual work and low efficiency, etc. In order to solve these problems, a tool which can automatically building spatial database based on the idea of visualization modeling has been studied and proposed in this article. The study shows that this technique helps greatly to decrease the complexity and cost for spatial database construction and improve the efficiency.
