【摘要】 快速城市化在带来社会经济效益的同时,也带来了众多城市问题,涉及到了生态环境恶化、交通拥堵、用地紧张等各个方面,严重威胁到了社会的和谐美好发展,城市的特色也在逐渐消失,其中“千城一面”的问题尤为突出,因此对城市形态进行分析和研究成为了学者们的研究热潮,并成为了城市地理学、以及在城市规划中的研究课题之一,在丰富学科理论的同时可指导实践的进行,具备极其重要的理论和实践意义。就目前国内外的研究进展来看,分形理论是走在新颖的道路上的,是典型的“非线性科学”,国外学者已将其运用到城市形态研究中,效果较好并取得了可观的研究成果。而在我国的应用中,则较晚,针对西南部城市的研究方面尤为少见。国外对分形理论的成功运用说明分形思想在针对城市形态研究方面具备理论和实践指导的能力。论文基于此背景,重点选取重庆为研究对象,着重探讨其城市形态特征和影响因素。论文首先概述了重庆城市形态演变的历史进程,简要分析了其影响因素,为后文近期的重庆形态演变研究做好分析准备。论文选取2000年、2005年、2010年、2015年为时间截面,运用arcgis对原始数据进行了解译和提取等处理,根据分形理论中的“周长——面积”计算法原理,利用spss对相关数据进行了分维值的计算,进而针对分维值大小所代表的不同含义进行了详细的阐述,分析出重庆城市形态的演变特征,结合重庆城市实际发展情况得出相应的影响因素,并参考2007~2020重庆城乡总体的规划方案和重庆中心城区城市形态演变现状,对重庆城市未来城市发展提出几点建议和策略,以期对重庆城市发展起到一定的引导作用。论文最后对前文进行了总结,说明了论文的主要创新点,并探讨了论文中可能存在的不足,期待其他学者在将来的研究中能更为全面和完善。更多还原

【Abstract】 While rapid urbanization brings social and economic benefits,it also brings many urban problems.It involves the deterioration of the ecological environment,traffic congestion,and land tense.It seriously threatens the harmonious and beautiful development of the society.The characteristics of the city are also gradually Disappearing,with the problem of "One Thousand Cities One Side" being particularly prominent,the analysis and study of urban morphology has become an upsurge of research among scholars.It also has become one of the research topics in urban geography and urban planning.The theory can guide the practice at the same time,and has extremely important theoretical and practical significance.According to current research progress at home and abroad,the fractal theory is on the novel path.It is a typical “non-linear science”.Foreign scholars have applied it to the study of urban morphology,and the effect is good and has achieved considerable Research results.However,in our country’s application,it is relatively late,especially for the research of the southwestern cities.The successful application of the fractal theory in foreign countries shows that the fractal theory has the ability of theoretical and practical guidance in the study of urban morphology.Based on this background,the dissertation focuses on the selection of Chongqing as the research object,focusing on the characteristics of its urban morphology and influencing factors.Firstly,the thesis summarizes the historical process of urban form evolution in Chongqing,and briefly analyzes the influencing factors,which makes preparations for the study of the recent Chongqing form evolution.The paper selects 2000,2005,2010,and 2015 as time sections,uses arcgis to process the translation and extraction of the original data,and uses the principle of “perimeter-area” calculation method in fractal theory to use spss for correlation.The data is used to calculate the fractal dimension,and the different meanings represented by the size of the fractal dimensions are elaborated in detail.The evolution characteristics of the urban form of Chongqing are analyzed,and the corresponding influencing factors are obtained based on the actual development of Chongqing cities.2007~2020 The overall plan for urban and rural development in Chongqing and the status of the evolution of urban form in Chongqing’s central city provide some suggestions and strategies for future city development in Chongqing,with a view to guiding the development of urban development in Chongqing.In the end,the thesis summarizes the previous article,explains the main innovations of the paper,and discusses the possible deficiencies in the paper,and expects other scholars to be more comprehensive and perfect in future research.更多还原
