面向人类行为研究的时空GIS

人类时空行为是地理学、物理学、规划学、流行病学等多学科共同关注的研究主题。时空GIS面向地理时空数据的建模与分析需求,注重时间与空间的一体化表达,为人类行为特征分析与规律探索提供基础方法支撑。然而,现有时空GIS在人类行为时空过程表达以及人类行为与时空场境交互分析等方面存在不足。本文通过深度融合时间地理学理论,提出一种面向人类行为研究的时空GIS方法,以丰富与完善现有的时空GIS方法体系。在深入解读时间地理学中“情境”、“企划”等核心概念的基础上,本文分别从情境要素存在性动态表达、情境要素相关性动态理解及情境要素变化的动态感知等方面探讨拓展现有时空GIS方法的可行性。

A Space-time GIS Approach for Human Behavior Studies

The study of spatial and temporal characteristics of human behavior has been widely noted among different disciplines such as geography, physics, planning and epidemiology. By integrating spatial and temporal dimensions, the space-time GIS provides a fundamental approach for the analysis and exploration of human behavior characteristics. However, the existing space-time GIS is not strong in some aspects, including representation of human behavior process in space and time as well as interactive analysis of human behavior in space-time contexts. This paper proposes a space-time GIS approach for human behavior studies, by bringing some core concepts of time geography such as "diorama" and "project", into space-time GIS, and discusses the potential and challenges from three aspects, including dynamic representation, correlation and variation perception of geographic entity in space and time.
