【摘要】：将中原经济区30个省辖市市区作为研究对象,按照由"线"→"点"→"面"的分析思路,运用引力模型、潜能模型与潜能得分模型、经济隶属度模型等各种模型,定量分析1990~2010年间中原经济区城市间相互作用时空格局的演变过程与特征。结果表明:城市间相互作用强度的时空差异明显。"线"层次上,城市间的引力和城市联结线数目的增多,逐渐形成辐射网络,引力和联结线数目的变化存在时空差异性。"点"层次上,通过"线-点"叠加分析,城市最大联结线数目增多和城市潜能等级提升的时空差异性明显。而且1990~2010年间各个城市潜能等级跃迁的时空差异明显。"面"层次上,近20多年来,区域中心城市没有变化,但4个中心城市的腹地变化明显,核心组团——郑州组团1990~2000年北扩,2000~2010年东扩;1990~2010年,潜能高值区域的空间收缩也表现出阶段性特征。
[Abstract]:Taking 30 municipalities and cities of the Central Plains Economic Zone as the research object, according to the analysis ideas of "line" and "point", the paper applies various models, such as gravity model, potential model and potential score model, economic membership model, etc. Quantitative analysis of the evolution process and characteristics of spatial and temporal patterns of urban interaction between cities in the Central Plains Economic Zone from 1990 to 2010. The results show that the spatial and temporal differences of interaction between cities are obvious. " On the line "level, the increase of gravity and the number of connecting lines between cities is gradually forming a radiation network, and the variation of gravity and the number of connecting lines is different in time and space." On the level of "point", through the superposition analysis of "line-point", the number of the largest connecting lines of cities and the spatial and temporal differences of the upgrading of urban potential grade are obvious. Moreover, the time and space difference of potential grade transition between 1990 and 2010 is obvious. " On the "plane" level, the regional central cities have not changed in the past 20 years, but the hinterlands of the four central cities have changed obviously. The core group-Zhengzhou group expanded northward from 1990 to 2000 and eastward expanded from 2000 to 2010. The spatial contraction of potential high-value region also shows the stage characteristic.
