【摘要】：通過構(gòu)建反映城市綜合實力的指標(biāo)體系,運用熵值法對中原城市群30個城市2005,2010,2015年的綜合實力分別進(jìn)行測算與評定,運用基于擴(kuò)展斷裂點模型的加權(quán)Voronoi圖方法對中原城市群各城市引力范圍進(jìn)行劃分并展示了城市間引力界線的變化趨勢,揭示了中原城市群30個城市3個年份的城市引力范圍時空演變特征和變化規(guī)律。結(jié)果表明:3個年份,綜合實力較高的地區(qū)基本分布在中原城市群中部和北部,東南部城市綜合實力較弱,排名靠后,呈現(xiàn)出中北高、東南低兩極化的發(fā)展規(guī)律;目前中原城市群城市引力范圍格局中,鄭州市的引力范圍最大,其次是洛陽市、邯鄲市,已經(jīng)形成了以鄭州為城市群核心的空間格局;3個年份,中原城市群的城市影響范圍演變格局總體較為穩(wěn)定,局部地區(qū)空間吸引范圍變化較為明顯,中、北部城市發(fā)展態(tài)勢良好,影響范圍有向北擴(kuò)大的趨勢;城市引力范圍與其綜合實力不完全呈正相關(guān)關(guān)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.
