【摘要】：伴隨著城市研究新數(shù)據(jù)源與方法論的興起,從時空間整合的角度反思和修正傳統(tǒng)的概念與方法,成為時空行為研究重要發(fā)展趨勢。地理背景作為城市研究的核心變量,其界定方式不確定性如何影響對個體行為作用效應(yīng)的分析結(jié)果,已成為地理學(xué)的新方法論問題。在已有文獻(xiàn)的基礎(chǔ)上,本文基于西寧市的實證研究,嘗試驗證地理背景不確定性對行為模式分析的影響,并進(jìn)一步探討多個行為變量與其相互關(guān)系以及時間維度差異。通過比較兩類地理背景范圍(僅考慮居住地建成環(huán)境的地理背景范圍、綜合考慮居住地與家外活動地建成環(huán)境的地理背景范圍),分析對個體行為作用效應(yīng)結(jié)果的差異性。研究發(fā)現(xiàn):如果僅以居住地作為地理背景范圍,關(guān)注其中建成環(huán)境對行為影響時,可能會夸大"家"的作用,而綜合考慮居住地與活動地的地理背景范圍時,更為接近于"真實"的地理背景,建成環(huán)境對家外活動時長、出行時長和活動空間有一定的解釋力,且能夠捕捉到一些重要的影響因素并修正有悖于常識的結(jié)論。同時地理背景不確定性對個體行為作用效應(yīng)的分析結(jié)果影響還表現(xiàn)出較明顯的工作日/休息日差異,表明地理背景存在時間維度的不確定性。研究結(jié)論在一定程度上揭示了時空行為研究在重新審視傳統(tǒng)城市地理學(xué)概念、探索日常生活視角的度量方法與研究范式方面的有效性。
[Abstract]:With the rise of new data sources and methodologies in urban research, it has become an important development trend to reflect and revise the traditional concepts and methods from the angle of time and space integration. As the core variable of urban research, how the uncertainty of the definition of geographical background affects the results of analysis on the effect of individual behavior has become a new methodology of geography. On the basis of existing literature, this paper tries to verify the influence of geographical background uncertainty on behavior pattern analysis, and further discusses the relationship between multiple behavioral variables and their temporal differences based on the empirical study in Xining city. By comparing the geographical background range of two kinds of geographical background (only considering the geographical background range of the built environment and synthetically considering the geographical background range of the place of residence and the environment built outside the home), the difference of the effect on individual behavior is analyzed. The study found that if only the place of residence was used as the geographical background, and when attention was paid to the effect of the built environment on behavior, the role of "home" might be exaggerated, while the geographical background of the place of residence and activity should be taken into account. More close to the "real" geographical background, the built environment has a certain explanatory power on the time of activities outside the home, travel time and activity space, and can capture some important factors and correct the conclusions contrary to common sense. At the same time, the effect of geographical background uncertainty on individual behavior also shows obvious difference between workday and rest day, which indicates that geographical background exists uncertainty in time dimension. To a certain extent, the conclusion reveals the effectiveness of spatio-temporal behavior research in re-examining the traditional urban geography concepts and exploring the measurement methods and research paradigms from the perspective of daily life.
