基于T-GIS方法的大学生时空变化规律研究

Changing Regularity of Spatio-temporal of College Students Based on T-GIS

T-GIS作为GIS的一个新兴研究领域,用于采集、存储、管理、分析与显示地理实体随时间变化的信息。结合T-GIS和时间地理学基本理论,以华中师范大学为例,分析了学生时空活动的动态表现,利用学生出行日志的问卷调查数据,开发了基于ArcGIS的大学生行为链时空分布工具,揭示了典型时间断面大学生的空间分布特征,为高校管理人员对大学生行为活动实施管理以及掌握校园相关设施、场所的利用情况等提供依据。该方法同样适用于其他与时态相关的领域。

As an emerging research area of GIS,T-GIS is applied in the collection,storage,management,analysis,and demonstration of the information of geography entity which changes along with the time variation.Based on the theories of T-GIS and Time Geography,this paper analyzed the dynamic performance of spatio-temporal activity of the students.And the household survey was conducted on students' daily activities and travel logs in Central China Normal University in Wuhan.A series of functions for recording and representing the spatio-temporal pattern for daily activities and travel chains was developed by C# language development platform of ArcGIS,which revealed the spatial distribution features of the college students at the typical time sections.The research can provide basis for the management of college students' behavior activities and master campus utilization of facilities and sites.This method can be applied in others fields which are related to temporal function.
