【摘要】 城市形态或称空间结构是城市发展程度、阶段与过程的空间反映，城市发展必然伴随形态的变化，并带来各种各样的城市问题。因此城市形态理论作为研究城市空间特征及其演化规律的城市科学的基本理论，一直受到学者们的重视。本文以武汉市为例，探讨了城市形态的相关理论和实践应用。全文分为两大部分三个章节，第一部分理论基础，第二部分案例分析。就人口，土地利用等部分全面解释了武汉市的城市空间形态的形成和发展，揭示了武汉特有的一些空间形态演变规律。 第一章对应基础理论，只是作了一般的转述，简要的解释，对城市形态理论及其相关概念进行了辨析，对1990年以来国内外学者在城市形态研究领域中的研究进展、取得的成绩、以及存在的主要问题进行了评述，并对未来城市形态研究的方向作出了展望。 第二章武汉市城市用地变迁与人口空间分布研究，进行了武汉市城市空间形态演变过程与用地变迁的定量化研究，分析了街区人口增长与空间分布变迁的规律。 第三章根据分形理论研究武汉1949-1996年间城市形态和土地利用结构的演化特征，发现武汉城市形态具有明确的自相似规律。研究表明，武汉城市形态和土地利用结构的分形性态逐渐变好，这与国外学者“演化的城市分形”观相互印证。各类土地形态的维数都小于整个城市形态的维数，从而证实了国内学者“城市化地区的分维大于各职能类土地空间分布维数”的理论推断。从时空变化来看，武汉城市形态的分维呈上升趋势，1996年接近Batty等提出的理论预期维数D=1.71；居住用地、工业用地和对外交通用地的分维近20年来趋于增大，而教育用地和绿化用地的分维则有所减小。武汉市的分形演化和分维变化总体上揭示了城市自组织演化的特征，但工业用地维数的大幅度上升和绿化用地维数的下降显然暗示该城市在进化过程中的局部退化倾向。 最后为论文的总结和展望，对本文的研究进行了全面总结，并指出下一步的研究方向和问题。更多还原

【Abstract】 Urban morphology is sometimes called Urban space construction.lt is the space reflect of city development degree, stage reflects with process.Urban morphology is changing with the city develops, and bring some kind of problem.For this reason ,it is attached importance to scholars as study urban space characteristic and evolvement orderliness of basic theories of urban science . Take Wuhan city for example, this paper discusses the correlative theories and practical applications of unbern morphology.The paper is divided into two parts , the first is the basic theorieses , the second is the cases and analysis.lt analysis and explain the form of population, land use of urban etc.lt describes the especial rules of urban morphology in Wuhan .The chapter one is the basic theorieses. It based on the introduction of basic concept of urban morphology,reviewed the latest evelopment and existing problem in the urban morphology studies,and presented some possible orientations in the future.The chapter two is about the variance of urban land ure and the research of population’s distributing in Wuhan.lt gives amensural research to the process about evolvement of urban morphology , the variance of land use in Wuhan and analyse the disciplinarian of block’s population increasing and the variance of space distributing.The chapter three is about the fractal theorieses. The author finds that the character of self-similarity is very clear in Wuhan when he studies the evolution of urban morphology and structure of urban land use using the theory of fractals. By dint of the box counting method, several maps of urban land use of different years are utilized to extract the basic data, and then the fractal dimensions of urban morphology and seven kinds of land are calculated. It is not difficult to find thatmost of the standard are less than the criterion 8c = 0.04, which was put forward by Benguigui etal. The author finds that the status of fractals of urban morphology and land use structure tend to be better with the elapse of time, which testify the viewpoint of foreign scholars about the evolving city fractals. Another important findings of the paper is that the fractal dimension of every land use is less than that of the total urban morphology, which is only a theoretical deduction before. From the viewpoint of spatial-temporal change, the fractal dimension of Wuhan’s urban morphology tends to be increasing, and in 1996 it is near D = 1.71, a mean value of fractal dimension summarized by Batty et al. As far as different urban land use of Wuhan is concerned, the fractal dimensions of residential, industrial and external traffic land tended to be increasing from 1980 to 1996, while the fractal dimensions of education and virescence land tended to be decreasing during the same period.The last chapter is conclusions and prospects. We summarize the whole thesis and represent the issues to be studied in the future.更多还原
