辽宁中部城市群城市体系中规模与距离关系的研究
发布时间：2018-08-27 19:57
【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:(1)城市i的规模Pi与"最近城市"n的规模Pn、距离D_(i-n) 以及区域中心城市c的距离D_(i-c) 有关,与首位城市的规模和距离无关,其中Pn、D_(i-n) 为正向影响,D_(i-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。(2)城市群中存在"城市距离-位序律"的定量关系。(3)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]:Taking the urban population scale and the distance between cities as indicators, the relationship between urban scale and spatial distance in the urban agglomeration of central Liaoning Province is analyzed quantitatively by multivariate regression model. And whether there is a quantitative relationship between the distance and distance order between the city and the nearest city, which is similar to the "law of city order and scale". The results show that: (1) the scale Pi of city I is related to the distance Di-n of "nearest city" n and the distance Di-c of regional central city, but independent of the scale and distance of the first city, in which Pn,D_ (i-n) is a positive influence and Di-c is a negative effect. In terms of influence, The influence of regional central city c is greater than that of "nearest city", which is different from other urban agglomerations in China. (2) there is a quantitative relation of "city distance order law" in urban agglomeration. (3) using the quantitative relationship between city size and distance, we can make use of the quantitative relationship between city size and distance. To calculate the size of the theoretical population and the scope of its influence, It provides a useful reference for population prediction and spatial structure division of central Liaoning urban agglomeration.
