摘要(Abstract):

我国中西部城镇化相对滞后,县域经济及县域城镇化发展缓慢是其主因,新型城镇化背景下,县域城镇化特征及规律受到普遍关注。自组织理论是揭示城镇化演化机制及空间特征的有效工具,通过对建国以来湖北省县域城镇化自组织演化过程的分析,揭示了湖北省县域城镇化经历的"萎缩徘徊—补偿增长—差异演化—深度分化"4个发展阶段的机制及其表现特征,在此基础上,选取湖北3类典型县域,运用分形方法,分别从城镇体系的规模等级性、空间向心性、均衡性及关联性等方面进行分析。研究表明湖北县域城镇体系具有分形特征,且3类县域城镇体系结构特征差异显著。以上发现可以为相关县域制定有针对性的城镇化空间组织引导对策提供理论依据。
For lagged development of county economy and urbanization, the urbanization process of middle-western China develops slowly. In the background of new urbanization, the characteristics and principles of county urbanization become a special concern. Self-organization theory has been an effective means to expose the urbanization evolution mechanism and spatial features. By analyzing the self-organization evolution of county urbanization in Hubei Province since the founding of PRC, the paper explores the mechanism and characteristics concerning the following four development periods: suspending and atrophy period, compensatory increase period, discrepancy evolution period, and depth differentiation period. The paper then selects three typical county types in Hubei Province and applies fractal methods, based on which it analyzes the scale hierarchy, spatial radial, spatial proportionality and spatial correlation. Research demonstrates that the county urban system in Hubei Province has fractal characteristics and there is noticeable discrepancy among structural features of the three types of county urban systems. In doing so, findings can provide theoretical support for the establishment of spatial organization guidance strategies for the urbanization of relevant counties.
