遼寧中部城市群城市體系中規(guī)模與距離關(guān)系的研究
發(fā)布時間:2018-08-27 19:57
【摘要】:以城市人口規(guī)模、城市間距離為指標,通過多元回歸模型,定量分析遼寧中部城市群中城市規(guī)模與空間距離的關(guān)系,以及城市與"最近城市"的距離和"距離位序"之間是否存在類似"城市位序-規(guī)模律"的定量關(guān)系。研究發(fā)現(xiàn):(1)城市i的規(guī)模Pi與"最近城市"n的規(guī)模Pn、距離D_(i-n) 以及區(qū)域中心城市c的距離D_(i-c) 有關(guān),與首位城市的規(guī)模和距離無關(guān),其中Pn、D_(i-n) 為正向影響,D_(i-c) 為負向影響。就影響力而言,區(qū)域中心城市c的影響大于"最近城市"n,這一點區(qū)別于國內(nèi)其他城市群。(2)城市群中存在"城市距離-位序律"的定量關(guān)系。(3)利用城市規(guī)模與距離的定量關(guān)系可以測算理論人口規(guī)模和影響范圍,為遼寧中部城市群的人口預(yù)測和空間結(jié)構(gòu)劃分提供有益參考。
[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.
