摘　　要： 基于时间地理学的概念模型，建立时空路径分析的GIS数据模型，并通过GIS三维可视化工具，实现了个体时空路径的三维可视化。运用2007年北京城市居民日常活动调查数据，对所提出的数据模型和方法进行实验。结果表明，时空行为数据的GIS分析方法有效地集成了GIS的空间分析和三维可视化功能，为人类时空行为数据的直观表现和分析提供了有效的技术手段。最后，讨论和展望了时空行为数据GIS分析方法的研究方向。 Time geography is a powerful conceptual framework for understanding constraints on human activity participation in space and time. Geo-visualization is an important approach to study spatial-temporal behavior. In this paper, the conceptual model of time geography is discussed first and data modeling of space-time path is built up. Next,a platform of mining temporal-spatial behavior patterns in ArcGIS environment is founded and 3D visualization of space-time path at individual level is realized. The capability of this prototype system has been demonstrated in an exploration of spatial-temporal behavior using data from activity diary survey collected in Beijing, 2007, from which a group of residents living in J iaodaokou community has been selected and applied. The system can allow users to retrieve and visualize spatial-temporal data according to various possible combinations of spatial, temporal, activity attribute and personal attribute criteria. The result shows that visualization is an effective method to identify spatial-temporal behavior patterns for it can integrate and analyze muhi-dimensional information together. Discussions of the benefits and shortcomings associated with this method are provided, along with suggestions for future research.
