【摘要】：既有低收入居民空間困境的研究以居住空間研究為主,關(guān)注低收入者受到的住房與社區(qū)隔離,難以刻畫低收入者在整日尺度面臨的時(shí)空制約。行為空間作為行為地理學(xué)與時(shí)間地理學(xué)的重要概念,為描述低收入居民在日常生活中面臨的移動(dòng)性與可達(dá)性相關(guān)的問(wèn)題提供了有力的工具。本文提出利用潛在活動(dòng)空間和實(shí)際活動(dòng)空間共同描述居民行為空間,分析低收入居民在時(shí)空可達(dá)性和實(shí)際利用城市空間能力上的劣勢(shì)�；�2012年北京市上地—清河居民活動(dòng)與出行日志,利用路網(wǎng)分析、最小多邊形分析等方法刻畫居民每日的潛在活動(dòng)空間和實(shí)際活動(dòng)空間。通過(guò)對(duì)不同收入群體的比較,發(fā)現(xiàn)低收入居民比其他居民的潛在活動(dòng)空間和實(shí)際活動(dòng)空間都要小。進(jìn)一步構(gòu)建模型分析潛在活動(dòng)空間和實(shí)際活動(dòng)空間的影響因素,發(fā)現(xiàn)包括收入在內(nèi)的個(gè)體社會(huì)經(jīng)濟(jì)屬性、空間屬性和行為屬性對(duì)潛在活動(dòng)空間和實(shí)際活動(dòng)空間存在影響,但是二者的影響因素存在差異。對(duì)行為空間的測(cè)量有利于增進(jìn)對(duì)于不同群體社會(huì)分異與空間隔離的認(rèn)知,對(duì)未來(lái)的研究具有重要的意義。
[Abstract]:The study of existing low-income residents' spatial predicament is mainly about residential space. It is difficult to describe the space-time constraints faced by low-income people on a whole day scale because they are concerned about the isolation of housing and community. As an important concept of behavioral geography and time geography, behavioral space provides a powerful tool for describing the mobility and accessibility problems faced by low-income residents in their daily life. In this paper, the potential activity space and the actual activity space are proposed to describe the resident behavior space together, and the disadvantages of the low-income residents in the space-time accessibility and the actual utilization of urban space ability are analyzed. Based on the activity and travel log of Shangdi-Qinghe residents in Beijing in 2012, the methods of road network analysis and minimum polygon analysis are used to depict the potential activity space and actual activity space. Through the comparison of different income groups, it is found that the potential activity space and actual activity space of low-income residents are smaller than those of other residents. The model is constructed to analyze the influence factors of potential activity space and actual activity space, and it is found that individual social and economic attributes, including income, spatial attribute and behavior attribute have influence on potential activity space and actual activity space. However, there are differences between the two factors. The measurement of behavior space is helpful to enhance the cognition of social differentiation and spatial isolation of different groups, and it is of great significance to the future research.
