摘要:

以城市人口规模、城市间距离为指标,通过多元回归模型,定量分析辽宁中部城市群中城市规模与空间距离的关系,以及城市与“最近城市”的距离和“距离位序”之间是否存在类似“城市位序-规模律”的定量关系。研究发现:城市i的规模Pi与“最近城市”n的规模Pn、距离Di-n以及区域中心城市c的距离Di-c有关,与首位城市的规模和距离无关,其中PnDi-n为正向影响,Di-c为负向影响。就影响力而言,区域中心城市c的影响大于“最近城市”n,这一点区别于国内其他城市群。城市群中存在“城市距离-位序律”的定量关系。利用城市规模与距离的定量关系可以测算理论人口规模和影响范围,为辽宁中部城市群的人口预测和空间结构划分提供有益参考。

Abstract:

The research establishes a multiple regression model according to city population and distance between cities, and quantitatively analyzes the relationship between city size and distance in urban system of Central Liaoning Urban Agglomeration to measure whether the distance between the city and the “nearest city” and the “distance order” have a similar quantitative relationship as the “Rank-Size Rule”. The results show: 1)in the Central Liaoning Urban Agglomeration, the population size of a certain city i (Pi) can be explained by the population size of the nearest city n (Pn) , the distance between n and i (Di-n), and the distance between the regional center city c and i (Di-c), but the size does not relate to the size and distance of the First city. In the relationships, Pn and Di-n have positive impacts on Pi, while Di-c has negative impact. Di-c is the most important factor, and its impact is bigger than Pn and Di-n, which is different from other urban systems in China. 2) The quantitative relationship between Di-n and ordinal number R of city n in the urban system is the same as the “Rank-Size Rule”. 3) The results indicate the quantitative relationship between population size and distance could estimate theoretical city sizes and influence range, which provides powerful evidence for population forecasts and spatial structure divisions of Central Liaoning Urban Agglomeration.

Key words: urban system, city size, distance between cities, Central Liaoning Urban Agglomeration
