摘　　要：介绍空间数据立方体在“数字城市”建设中的作用以及国内外研究现状;讨论非空间维、空间维、数字度量、空间度量的基本概念和结构,给出空间数据立方体的完整描述。空间数据立方体的分析操作主要由概括分析、局部分析、全局分析和旋转分析组成,介绍这些分析操作的功能和结构;结合具体实例数据介绍多维缓冲区空间分析。This paper introduces researches on spatial data cube on abroad and home,and explains the concept and structure of non spatial dimension, spatial dimension, digital measure and spatial measure of spatial data cube, and gives definition of spatial data cube. This paper states basic concept and principle of analytical operation on spatial data cube, and also indicates that analytical operation comprises recapitulative analysis, local analysis, global analysis and pivoting analysis. According to these, this paper recites completely function and structure of above analysis and detail process of analytical operation for multi - dimension analyses. In the process of analysis, the methods that show example for these analysis functions are adopted in order to make reader more intelligible.
