【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]:By constructing an index system reflecting the comprehensive strength of cities, the comprehensive strength of 30 cities in the Central Plains urban agglomeration in 2005 / 2010 and 2015 is calculated and evaluated by using entropy method. Using the method of weighted Voronoi diagram based on extended fault point model, the gravity range of cities in Central China urban agglomeration is divided and the variation trend of gravity boundary between cities is shown. The spatial and temporal evolution characteristics and variation rules of urban gravity range in 30 cities of Central Plains in 3 years are revealed. The results show that in the three years, the areas with high comprehensive strength are basically distributed in the central and northern parts of the urban agglomeration, and the comprehensive strength of the southeast cities is weak, which shows the development law of high and low polarization in the central and northern parts of China. At present, Zhengzhou has the largest gravitational range, followed by Luoyang and Handan, which has formed the spatial pattern with Zhengzhou as the core of urban agglomeration. In three years, the evolvement pattern of urban influence scope of urban agglomeration in Central Plains is stable in general, and the spatial attraction range of local area is obvious. In the middle and north, the urban development situation is good, and the influence range is expanding northward. The range of urban gravity is not completely correlated with its comprehensive strength.
