摘要: 等级规模结构是城市体系的3大结构之一,其特征可以反映出城市在不同规模层次中的分布状况及城市人口集中或分散程度,有助于认识城市体系发展所处的阶段。本文通过运用城市首位度、分形、城市重心转移等理论和方法,对辽宁中部城市群城市体系等级规模结构进行了分析。结果表明:辽宁中部城市群城市体系等级规模结构具有分形特征,城市规模分布呈首位分布,等级序列中中等城市数量较少;城市规模空间分布趋向均衡,但发展过程具有显著的区域差异;从1982—2005年城市人口重心总体向西南方向移动。

Abstract: Hierarchical structure is one of the main three structures in urban sy stem. Its characteristics can reflect the distribution patterns of cities in dif ferent scales and the degrees of concentration or dispersion of urban population , and also, can help us to understand the development stage of urban system. By using the theories and methods of urban primacy index, fractal, and urban gravit y transfer, the hierarchical structure of urban system in the multi-cities of c entral Liaoning were analyzed. The results showed that the multi-cities of cent ral Liaoning had a fractal hierarchical structure, their sizes were in primacy d istribution, and middle-size cities were fewer. The spatial distribution of cit y size tended to balance, but the development process had significant regional d ifference. From 1982 to 2005, the gravity of urban population had an overall sou thwestward transfer.
