文章摘要：時(shí)空間行為是解讀城市空間結(jié)構(gòu)的重要視角。轉(zhuǎn)型期中國(guó)城市居民的時(shí)空間行為呈現(xiàn)出復(fù)雜化、彈性化與個(gè)性化等趨勢(shì),短期行為與長(zhǎng)期行為的關(guān)系與作用機(jī)理亦成為關(guān)鍵研究問(wèn)題。本研究基于北京市GPS調(diào)查獲取的100位郊區(qū)居民的一周時(shí)空間行為數(shù)據(jù),采用三維可視化、描述性統(tǒng)計(jì)與方差分析的方法,研究居民一周的時(shí)空路徑和時(shí)間分配的日間差異。結(jié)果表明：一周之內(nèi)居民時(shí)空間行為在工作日與休息日之間的差異顯著。工作日中,周一的工作時(shí)間最長(zhǎng),家外非工作活動(dòng)的發(fā)生率及發(fā)生時(shí)間均較低;周二至周四居民行為的差異性相對(duì)較小;周五是工作日向休息日的過(guò)度時(shí)期,居民具有較高的時(shí)間分配自由度。休息日之間居民的時(shí)間分配差異不顯著。

Abstr：Research on human activity-travel behavior is offering an important approach to the study of urban structure. There have been lots of domestic empirical studies on space-time patterns and the related decisions process based on cross-sectional data or activity diary of one or two days. But less time has been spent on space-time behavior and the variations during a period more than two days, because long-term disaggregated space-time data of individual＇s behavior is hard to achieve, and on the other hand, individuals are generally assumed to establish stable, highly routinized patterns. As long-term activity-travel dairy surveys are achieved in increasing countries, how an individual＇s behavior varies from day to day, week to week, or season to season, has been discussed intensively by researchers to gain a better understanding of activity-travel behavior and to acquire knowledge for better planning and policy development. In transitional China, space-time behavior of residents is more and more complicated, flexible and individualized, day-to-day variability in activity-travel behavior has become an important theme. Data for this study are drawn from a 2010 Beijing one-week activity-travel survey based on GPS, including 100 residents in two typical suburban communities. We use a time geographical framework to represent the activity-travel trajectories in 3-D GIS environment, and also descriptive analysis and analysis of variance to study day-to-day variability in activity-travel behavior during one week from perspectives of space-time path and time allocation. The results indicate that, firstly, differences of residents＇ space-time behavior between weekdays and weekends are significant. Second, during the weekdays, Monda
