地理背景的不确定性对时空行为模式分析的影响——基于西宁市的实证研究
发布时间：2018-11-05 15:52
【摘要】：伴随着城市研究新数据源与方法论的兴起,从时空间整合的角度反思和修正传统的概念与方法,成为时空行为研究重要发展趋势。地理背景作为城市研究的核心变量,其界定方式不确定性如何影响对个体行为作用效应的分析结果,已成为地理学的新方法论问题。在已有文献的基础上,本文基于西宁市的实证研究,尝试验证地理背景不确定性对行为模式分析的影响,并进一步探讨多个行为变量与其相互关系以及时间维度差异。通过比较两类地理背景范围(仅考虑居住地建成环境的地理背景范围、综合考虑居住地与家外活动地建成环境的地理背景范围),分析对个体行为作用效应结果的差异性。研究发现:如果仅以居住地作为地理背景范围,关注其中建成环境对行为影响时,可能会夸大"家"的作用,而综合考虑居住地与活动地的地理背景范围时,更为接近于"真实"的地理背景,建成环境对家外活动时长、出行时长和活动空间有一定的解释力,且能够捕捉到一些重要的影响因素并修正有悖于常识的结论。同时地理背景不确定性对个体行为作用效应的分析结果影响还表现出较明显的工作日/休息日差异,表明地理背景存在时间维度的不确定性。研究结论在一定程度上揭示了时空行为研究在重新审视传统城市地理学概念、探索日常生活视角的度量方法与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.
