【摘要】:作為我國(guó)歷史文化遺產(chǎn)重要組成部分的近代開埠城市,由于其特殊的地理區(qū)位與社會(huì)歷史背景,集中地反映出文化沖突、空間塑造及城市發(fā)展的規(guī)律性,因而在城市空間形態(tài)演變及其動(dòng)力機(jī)制研究中具有重要的研究?jī)r(jià)值。目前國(guó)內(nèi)關(guān)于開埠城市空間形態(tài)演變的動(dòng)力機(jī)制研究,多停留在對(duì)有關(guān)影響因素的羅列上,對(duì)各動(dòng)力機(jī)制的作用方式、作用深度、相互關(guān)系等研究還不夠深入,尤其欠缺量化的研究。近年來學(xué)界興起的多主體仿真方法為這一研究提供了新的視角:它基于復(fù)雜系統(tǒng)理論“自下而上”的角度,通過模擬大量微觀個(gè)體的行為來研究系統(tǒng)的宏觀規(guī)律,因而帶來了新的研究契機(jī)。論文首先對(duì)城市空間形態(tài)的概念進(jìn)行了定義,并分別對(duì)國(guó)內(nèi)外開埠城市空間形態(tài)演變的研究成果及多主體仿真在城市空間形態(tài)領(lǐng)域的應(yīng)用進(jìn)行了概述。其次,簡(jiǎn)述開埠城市設(shè)立始末及分布特征,總結(jié)沿海、沿河及東北地區(qū)開埠城市空間形態(tài)演變的一般過程,在此基礎(chǔ)上歸納出開埠城市空間形態(tài)演變的主要?jiǎng)恿C(jī)制。而后通過介紹多主體仿真在城市空間形態(tài)演變機(jī)制中的應(yīng)用,為下文建立近代天津城市空間形態(tài)演變模型提供理論基礎(chǔ)。通過剖析近代天津城市商業(yè)中心演變的動(dòng)力機(jī)制,建立多個(gè)多主體仿真模型,模擬近代天津城市商業(yè)中心在動(dòng)力機(jī)制合力下的演變,尋求與城市空間發(fā)展史實(shí)最吻合的動(dòng)力機(jī)制組合方案,以此作為發(fā)現(xiàn)動(dòng)力機(jī)制構(gòu)成機(jī)理的路徑,并嘗試通過改變動(dòng)力機(jī)制作用力大小來探討城市空間形態(tài)演變的多種可能性。論文最后評(píng)析了多主體仿真應(yīng)用的優(yōu)勢(shì):其能夠?qū)⑽⒂^個(gè)體與宏觀環(huán)境巧妙聯(lián)系的特性,使得更加清晰、量化地了解各動(dòng)力機(jī)制對(duì)近代天津城市空間形態(tài)演變的影響與作用成為可能;進(jìn)一步分析了多主體仿真研究的難點(diǎn)與不足,并對(duì)開埠城市空間形態(tài)演變研究提供展望。
[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.
