| 摘 要： | 通过构建反映城市综合实力的指标体系,运用熵值法对中原城市群30个城市2005,2010,2015年的综合实力分别进行测算与评定,运用基于扩展断裂点模型的加权Voronoi图方法对中原城市群各城市引力范围进行划分并展示了城市间引力界线的变化趋势,揭示了中原城市群30个城市3个年份的城市引力范围时空演变特征和变化规律。结果表明:3个年份,综合实力较高的地区基本分布在中原城市群中部和北部,东南部城市综合实力较弱,排名靠后,呈现出中北高、东南低两极化的发展规律;目前中原城市群城市引力范围格局中,郑州市的引力范围最大,其次是洛阳市、邯郸市,已经形成了以郑州为城市群核心的空间格局;3个年份,中原城市群的城市影响范围演变格局总体较为稳定,局部地区空间吸引范围变化较为明显,中、北部城市发展态势良好,影响范围有向北扩大的趋势;城市引力范围与其综合实力不完全呈正相关关系。

| Abstract: | Delimitating Scientifically and reasonably urban attractive scope is significant to the construction of urban agglomeration and the development of the country as a whole.By establishing an evaluation index system of the city comprehensive power,this paper uses entropy method to calculate the comprehensive power of thirty cities of Zhongyuan Urban Agglomeration in 2005,2010 and 2015 respectively.On the basis of this,the space attractive scopes of thirty cities of Zhongyuan Urban Agglomeration in four years are divided by weighted voronoi diagram based on expanded breaking point theory,and clearly shows the trend of the change of the attractive scopes between cities on diagrams.According to the division result,the features of temporal spatial evolution and change laws of spatial differentiation of the city attractive scope of Zhongyuan Urban Agglomeration during 2005-2015 are revealed.The result shows that the comprehensive strength of the higher area basically distributed in the city group of Central Plains of central and northern region,south-east of the city's comprehensive strength is weak,the ranking,showing the north high,southeast low polarization development law.At present,the gravity range of Zhengzhou city is the largest,and Luoyang and Handan are closely followed.The scope of urban influence in Central Plains urban agglomeration is generally stable,and the scope of spatial attraction in some areas is more obvious.The trend of urban development in north central part is good,and the scope of influence is northward expansion.The range of urban gravitation is not completely related to its comprehensive strength. |
