【摘要】 90年代以来我国有着新的经济社会背景,城市形态演变呈现新的特征,有着新的动力和机制,及时总结,对城市理论是有益的补充和完善。城市形态演变研究的实践性强,直接关系到城市发展规模、城市发展方向、城市功能组织、城市交通组织、城市绿地系统等方方面面,在目前我国城市扩展迅速、规划实践空前发展的情况下,开展此项研究对规划管理和编制实践均有重要的实践价值。本文通过对国内外城市形态研究的综述,指出由表及里,层层深入是本研究观察问题的基本途径;从实践中来,到实践中去,不断循环反复,逐步提高是本研究解决问题的基本方法;以人为本是本研究判断问题的基本标准。首先从城市内部结构的急剧变化和外部轮廓的迅速扩展两个方面归纳了90年代以来我国城市形态演变的总体特征,指出两者互相关联、互为因果,是一个动态的过程。其次从90年代以来新的社会经济背景出发,建立了信息化、全球化、知识经济和快速城市化与城市形态演变的基本联系,在新的时代背景中考察城市形态的动态演变。分析了推动城市形态演变的内在动力,分别为经济增长、功能调整、新的消费需求等,外在动力分别为快速交通、行政区划的调整等,指出城市形态演变是内外动力共同作用的结果,体现出了城市形态演变的复杂性。揭示了推动城市形态演变的机制,分别为市场机制、产业进化机制、投资机制和调控机制,认为无形的机制的综合作用引起了城市形态有形的变化。城市形态演变的机制并不是一个线性的具有明显因果关系的过程,而是一个非线性的多因素多层面的交织耦合过程。同时,各机制之间存在着相互反馈,机制之间的相互联系与作用,体现出了城市形态演变的综合性。基本总结了90年代以来我国城市形态的演变,指出外延跳跃是城市形态演变的主要形式,以产业空间为中心的新空间主导城市形态的演变,人文关怀和人地和谐将是城市形态演变的主要方向,认为这既是中国转型期的特色,也适应于发展中国家的城市发展。还从形态的协调性,形态的成长性,形态的生态性,形态的经济性等方面初步提出合理形态的评价标准,为规划编制和管理提供有益的参考,最后指出了本研究的不足和今后研究的方向。更多还原

【Abstract】 Since 1990s, there are new economic and social backgrounds in China. Due to the new mechanism and dynamic characteristics of urban morphology evolution, it is very important to get some new conclusion for the amendment of city theories. The research on urban morphology evolution is highly related to the scale of urban development, direction of urban expansion, city function, traffic organization, urban open space system, etc. This kind of research is highly valued for planning administration and planning practicality, especially on such a high speed of urban expansion and well-developed city planning.This thesis is based on the review of urban morphology researches both in China and aboard. In the thesis, human beings have been taken as the foundation of all values, plus the consideration of practicality.First, the characteristics of urban morphology evolution since 1990s in China have been summarized from two aspects: urban inner configuration, urban the outer shape. And a mutual relation and dynamic process have been identified in this analysis.Second, the interrelations between urban morphology evolution and informationzation, globalization, knowledge economy and rapid urbanizing have been developed based on a new social economic background since 1990s. The inner drive forces for urban morphology evolution are economical increases, function adaptation and new consuming requirement. The outer drive forces include rapid traffic conditions, adjustment of administrative division, etc. The urban morphology evolution is the results of both inner and outer drive forces, indicating the complexity of urban morphology evolution. Four incorporeal parts control the function of urban morphology evolution: marketing, industrial evolution mechanism, and investment mechanism and regulating mechanism.The function of urban morphology evolution is not a clearly linear law of causation but a nonlinear process caused by various mechanisms, which have feedbacks to each other. The major way of urban morphology evolution is the extension transit, and the new space focused on industrial location is the most important factor for the urban morphology evolution. The author also concludes that humanitarianism and harmony between human beings and nature play a vital role in urban morphology evolution, which is not only the Chinese characteristic during the transformation, but also adapted for the urban development in developing countries.The author also proposed a new index system for assessing the urban morphology, which is based on harmonization, growth degree, ecology and economy. Such a index system is also useful for planning practicality and planning administration. Moreover, the open questions in this field and the trends in future are also discussed.更多还原
