| 摘 要： | 城镇体系结构是城市化格局及演化的基本框架.以西陇海兰新经济带甘肃段为例,利用甘肃段41个县及以上城镇统计资料,结合相关分析模型、分形理论和GIS空间分析方法,从城镇体系等级规模结构、空间结构及与城市化的定量关系入手,探讨了城镇体系结构基本特征以及与城市化的时空耦合机制,得到以下结论:1]甘肃段城镇体系结构以2002年为转折点,进入第二阶段的倾斜发展,其特征表现为:等级规模不服从位序-规模法则,属典型首位分布;等级规模结构具有分形特征,单核心增长格局发生分异;空间结构具有分形特征,呈点轴空间分布格局.2]城市化水平的高低不仅取决于城市规模的大小(与城市规模呈对数关系),还取决于等级规模结构的均衡性(其对数与不均衡指数成线性关系),同时,城镇体系的空间结构影响其发展的进程.并藉此探讨了甘肃段城镇体系及城市化未来发展方向与策略.

| Abstract: | The structure of urban system is the basic framework of the pattern and evolution of urbanization.This article takes western Longhai-Lanxin economic zone in Gansu as an example,uses statistical data of 41 counties and the above cities in Gansu section,combining the correlation analysis model,the fractal theory and the GIS spatial analysis method,from the urban system rank scale structure,the spatial structure and the urbanized quota relations,discusses the cities architecture essential feature as well as wi... |
