【摘要】：分形理论始于1967年,而我国正式引入分形理论是在90年代初期,经过国内外共同探讨、研究,分形理论的基础内涵、理论模型、实证研究等方面逐渐趋于成熟。经国内外学者证明,分形理论不仅适用于经济带的城镇体系结构研究,而且表现出科学、有效、便捷等特点。在一个特定的地域中,由具有职能、层次、分工、规模等方面的差异,彼此作用、紧密联系的城镇集合被称为城镇体系。城镇体系结构研究包括了等级规模、空间分布、职能体系三个方面,是城市地理学研究的主要领域之一。研究珠江—西江经济带的城镇体系结构特征,为其制定科学的城镇体系发展对策,对促进区域经济增长、社会发展有重要的意义。但就目前的研究现状来看,关于珠江—西江经济带城镇体系相关的研究较为缺乏,不能满足指导其城镇体系发展的需要。本文运用了一般分析和分形研究两种手段去分析研究珠江—西江经济带的城镇体系结构。一般分析:(1)由经济带的各市的综合发展水平入手,使用主成分分析方法和系统聚类分析方法对其进行定性评价,发现11座城市的整体发展水平可以分类三类;(2)根据经济带的城镇化进程,对其发展现状进行定性的描述分析,其城镇化的发展现状主要呈现四个特征;(3)分析经济带的城市指数和各市的城镇密度发现经济带城镇的规模结构主要呈现较为复杂、松散的特点,而空间分布则沿上游至下游,城镇密度增大;(4)按照城镇的主导职能来划分把城镇体系分为交通枢纽型、工矿型等8种类型。分形研究:本文分运用了分形理论的数学模型,分别对珠江—西江经济带城镇体系的规模结构和空间分布进行了定量的测算分析,总结出经济带城镇体系具有规模等级发育不完善、空间结构沿轴线分布等四个分形特征。综合珠江—西江经济带城镇体系整体的一般研究和分形研究结果,为经济带城镇体系的发展作出了优先发展小城镇、大力发展中小城市和积极发展特大城市和大城市的总体定位,确定进一步优化城镇体系的空间布局、完善城镇体系规模结构和强化城镇的主导职能的基本构想;提出以城乡一体化为战略促进小城镇建设发展、以城镇合作发展为路径增加中小城市数量等具体可操作的城镇体系发展建议。在文章最后,归纳总结了6点关于珠江—西江经济带城镇体系结构的研究结论,并且从研究的内容、数据和模型揭露了本文研究的对于城镇体系的形成机制和发展轨迹的描述尚有欠缺、忽略了各城镇间的交通网络通达性的研究等方面存在一定的不足之处。
[Abstract]:Fractal theory began in 1967, but fractal theory was formally introduced in the early 1990s in China, through the domestic and foreign common discussion, research, the basic connotation of fractal theory, theoretical model, empirical research and so on gradually tend to mature. It has been proved by domestic and foreign scholars that fractal theory is not only suitable for the study of urban system structure of economic belt, but also has the characteristics of scientific, effective and convenient. In a particular region, the collection of towns with functions, levels, division of labor, scale, and so on, which is closely related to each other, is called the urban system. The study of urban system structure includes three aspects: hierarchical scale, spatial distribution and functional system, which is one of the main research fields of urban geography. It is of great significance to study the characteristics of urban system structure of Zhujiang Xijiang economic belt and to formulate scientific countermeasures for the development of urban system to promote regional economic growth and social development. However, according to the present research situation, the research on the urban system of Zhujiang-Xijiang economic belt is relatively lacking and can not meet the needs of guiding the development of the urban system of Zhujiang-Xijiang economic belt. In this paper, general analysis and fractal analysis are used to analyze and study the urban system structure of Zhujiang-Xijiang economic belt. General analysis: (1) starting with the comprehensive development level of each city in the economic belt, using the principal component analysis method and the system cluster analysis method to carry on the qualitative evaluation to it, It is found that the overall development level of 11 cities can be classified into three categories. (2) according to the urbanization process of the economic belt, the qualitative description and analysis of the development status of the 11 cities are carried out. The present situation of urbanization mainly presents four characteristics: (3) analyzing the city index of economic belt and the urban density of each city, we find that the scale structure of economic belt is mainly complex and loose, while the spatial distribution is along the upstream to downstream. (4) according to the leading function of the town, the urban system can be divided into eight types, such as transportation hub type, industrial and mineral type, etc. Fractal study: this paper uses the mathematical model of fractal theory to calculate and analyze quantitatively the scale structure and spatial distribution of urban system in Zhujiang Xijiang economic belt. It is concluded that the urban system of economic belt has four fractal characteristics, such as the imperfect development of scale and grade and the distribution of spatial structure along the axis. By synthesizing the general research and fractal research results of the whole urban system of Zhujiang and Xijiang Economic Belt, priority has been given to the development of small towns in the economic belt. The overall orientation of developing small and medium-sized cities and actively developing mega-cities and large cities should be determined to further optimize the spatial layout of urban system, to perfect the scale structure of urban system and to strengthen the leading functions of cities and towns. The paper puts forward some practical suggestions such as urban and rural integration as a strategy to promote the construction and development of small towns, and urban cooperative development as the path to increase the number of small and medium-sized cities. At the end of the article, it summarizes the conclusion of the research on the urban system structure of Zhujiang Xijiang economic belt, and from the content of the research, The data and model reveal that the description of the formation mechanism and the development track of the urban system in this paper is still deficient, and the research on the accessibility of the traffic network between the cities and towns is neglected.
