复杂情境中的日常活动可视化与应用研究

时间地理学以时空路径为代表的符号系统由于具备抽象、简明、直观等特点,在地理学及其他社会科学领域得到了广泛传播与应用。随着GIS与地理可视化技术的不断进步、高精度时空行为数据的批量生产等,真实地理环境中个体时空运动轨迹的三维可视化技术也在不断进步。信息化社会的到来与城市社会转型等使得现代社会中的人类日常活动变得十分复杂,时间地理学由于直观刻画时空间中人类活动的时空连续性与复杂情境性而备受关注。本文首先界定了人类日常活动复杂情境的分析维度,包括日常情境、企划情境、地理情境、社会情境、技术情境等,并在此基础上将绝对时空间坐标系下的时空路径拓展到相对时空观下多维活动序列的可视化表达。其次,简单说明Daily life与VISUAL-Time PAc TS/energy use等可视化工具,介绍时空路径在复杂情境性下的可视化、模式挖掘及个案分析。最后,案例分析个体与群体尺度上活动情境可视化方法在家庭成员间分工与互动、日常活动模式差异与家庭能源消耗差异等方面的应用。

VISUALIZATION AND APPLICATIONS OF DAILY ACTIVITIES IN THE COMPLEX CONTEXT

The notations system of time-geography, especially path (or trajectory) put forward by Hägerstrand has been widely spread and applied in many research fields in geography and other social sciences due to its abstraction, simplification and intuition. Along with the advance of GIS and geo-visualization and mass production of high precision spatial-temporal data, the 3D visualization technology of individual space-time path in real geographical environment has also been in progress since 1990s. This paper, firstly defines and interprets the different dimensions of the complex context of human everyday activities, including "everyday context" used to emphasize the sequence of activity time, "project context" used to emphasize the internal connection of activities, "geographical context" used to emphasize the sequence of activity place, as well as "social context" used to emphasize the social connection of activities. After then, this paper briefly describes two visualization tools called "Daily life" and "VISUAL-TimePAcTS/energy use". Finally, this paper introduces the application of the visualization method with the case studies on the domestic division of labor and interaction between members in household level.
