摘　　要：城市发展进程中典型事件下的城市形态和空间结构诸方面特征,是城市历史文化演变在地域空间上留刻的有形足迹,它的数据表达能够对城市演变和发展研究形成基础和有效支持。时空数据模型因其能够完整表达客观世界时间、空间和特征语义,是重要的历史、地理和文化信息描述工具。以北京为背景,提取城市发展过程中典型历史事件,研究其下的时空数据事实和特征,提出基于历史事件的多维星座快照模型。该模型综合多维星座模型和时间快照模型的特点,以关系模型为主题框架,表达北京各时期历史和地理特征,为建立时空数据集成和城市空间特征分析的数据仓库模型提供概念表示。To support the studies of urban evolution and development about urban form and spatial structure, the data expression of the characteristics of urban form and spatial structure is a basis. The characteristics are based on some typical events during ur- ban development as the tangible footprints carved on regional space. As an important tool to express information of history, geog- raphy and culture, the spatio-temporal data model can completely express time, space and semantic feature of the objective world. The typical events of Beijing during urban development are extracted. A multi-dimension constellation snapshot data model is presented to study the facts and characteristics of spatio-temporal data based on the historical events. This model based on rela- tional frameworks synthesizes the traits of multi-dimension constellation model and snapshot data model to express features of his- tory and geography at different stages in Beijing. It offers a conceptual representation for dataware model for spatio-temporal data integration and analysis of spatial features.
