【摘要】：作为我国历史文化遗产重要组成部分的近代开埠城市,由于其特殊的地理区位与社会历史背景,集中地反映出文化冲突、空间塑造及城市发展的规律性,因而在城市空间形态演变及其动力机制研究中具有重要的研究价值。目前国内关于开埠城市空间形态演变的动力机制研究,多停留在对有关影响因素的罗列上,对各动力机制的作用方式、作用深度、相互关系等研究还不够深入,尤其欠缺量化的研究。近年来学界兴起的多主体仿真方法为这一研究提供了新的视角:它基于复杂系统理论“自下而上”的角度,通过模拟大量微观个体的行为来研究系统的宏观规律,因而带来了新的研究契机。论文首先对城市空间形态的概念进行了定义,并分别对国内外开埠城市空间形态演变的研究成果及多主体仿真在城市空间形态领域的应用进行了概述。其次,简述开埠城市设立始末及分布特征,总结沿海、沿河及东北地区开埠城市空间形态演变的一般过程,在此基础上归纳出开埠城市空间形态演变的主要动力机制。而后通过介绍多主体仿真在城市空间形态演变机制中的应用,为下文建立近代天津城市空间形态演变模型提供理论基础。通过剖析近代天津城市商业中心演变的动力机制,建立多个多主体仿真模型,模拟近代天津城市商业中心在动力机制合力下的演变,寻求与城市空间发展史实最吻合的动力机制组合方案,以此作为发现动力机制构成机理的路径,并尝试通过改变动力机制作用力大小来探讨城市空间形态演变的多种可能性。论文最后评析了多主体仿真应用的优势:其能够将微观个体与宏观环境巧妙联系的特性,使得更加清晰、量化地了解各动力机制对近代天津城市空间形态演变的影响与作用成为可能;进一步分析了多主体仿真研究的难点与不足,并对开埠城市空间形态演变研究提供展望。
[Abstract]:As an important part of China's historical and cultural heritage, the modern port city, due to its special geographical location and social and historical background, reflects the laws of cultural conflict, space shaping and urban development. Therefore, it has important research value in the study of the evolution of urban spatial form and its dynamic mechanism. At present, the domestic research on the dynamic mechanism of the spatial evolution of the open port city mostly stays on the list of the relevant influencing factors. The research on the mode of action, the depth of the action and the mutual relationship of the various dynamic mechanisms is not deep enough. In particular, there is a lack of quantitative research. The emerging multi-agent simulation method in recent years provides a new perspective for this study: it is based on the theory of complex systems, "bottom-up" perspective, by simulating the behavior of a large number of micro-individuals to study the macro laws of the system. This brings a new opportunity for research. Firstly, the concept of urban spatial form is defined, and the research results of the evolution of urban spatial form at home and abroad and the application of multi-agent simulation in the field of urban spatial form are summarized. Secondly, the paper briefly describes the initial and distribution characteristics of the opening city, summarizes the general process of the spatial evolution of the coastal, river and northeast cities, and on this basis, summarizes the main dynamic mechanism of the spatial form evolution of the port city. Then, by introducing the application of multi-agent simulation in the evolution mechanism of urban spatial form, this paper provides a theoretical basis for the following establishment of modern Tianjin urban spatial morphology evolution model. By analyzing the dynamic mechanism of the evolution of the modern Tianjin city commercial center, a number of multi-agent simulation models are established to simulate the evolution of the modern Tianjin city commercial center under the combined force of the dynamic mechanism. This paper seeks the combination scheme of dynamic mechanism, which is most consistent with the historical facts of urban spatial development, as a way to find out the mechanism of dynamic mechanism, and tries to explore the possibility of the evolution of urban spatial form by changing the force of dynamic mechanism. At the end of the paper, the advantages of multi-agent simulation are analyzed: it can connect micro individuals with macro environment cleverly, which makes it more clear. It is possible to quantitatively understand the influence and function of various dynamic mechanisms on the evolution of urban spatial form in modern Tianjin. The difficulties and shortcomings of multi-agent simulation are analyzed, and the prospect of spatial evolution of open-port city is provided.
