摘　　要：本文旨在解决从多源异构、多维的城市建设用地空间数据中深入挖掘有效信息的难题,从城市建设用地空间数据仓库构建的需求出发,对空间数据仓库的相关概念进行了分析探讨,包括数据立方体、维、度量、事实等。同时,以城市建设用地利用为主题,建立了多维数据模型,提出了构建城市建设用地空间数据仓库的具体流程与方法。并以北京市中心城区的建设用地利用为例,从建设高度、建筑基底面积等角度研究了北京市城市建设用地的利用强度特征。For the characteristics of urban construction land data, such as multi-source, heterogene- ous, multi-dimensional and high complexity, mining the potential spatial information of urban construction land based on spatial data warehouse theory was discussed in this paper. First, spatial data warehouse con- cept was analyzed and discussed, including data cube, dimension, measure and facts and so on. Multi-di- mensional data model-oriented urban construction land use was put forward and designed to build spatial data warehouses in the theme of urban construction land use and to achieve spatial data mining process. Taking construction land in Beijing central city for example, the use intensity of urban construction land on building height and basement area was researched to provide methodology and reference for management, integration, analysis, and high-level decision-making of urban construction land.
