【摘要】：城市的中心性反映一个城市为其以外地区提供服务的相对重要性。本文以长江中游城市群各城市统计数据、统计年鉴为基础,利用熵值法、ArcGis空间分析等计量方法,对2005-2014年城市群城市中心性进行综合分析,从整体、区域和城市群三个方面对其中心性进行了全面评价。结果表明:(1)地市尺度中,对城市中心地位评价,从时间变化来看,武汉市、长沙市和南昌市城市中心地位较高。孝感市、湘潭市和荆门市城市中心地位提升较快,荆州市城市中心地位下降较快。从空间变化来看,武汉市凭借卓越区位优势、雄厚经济实力和庞大科教资源,成为长江中游城市群的首位城市。对城市基本职能评价,从时间变化来看,各地市生产职能、商贸职能、信息职能、交通职能、金融职能、科教职能、文化职能、医疗职能均有所提升。生产职能、商贸职能和交通职能提升明显,而文化、医疗和金融等职能提升较慢。从空间变化来看,武汉市、长沙市和南昌市城市各项职能突出并且提升较快,城市基本职能发育较为完全,属于综合性城市,其余城市与之对比,城市职能发育较弱。对城市等级体系评价,武汉市和长沙市属于一级中心中心,南昌市等13个城市为二级中心城市,仙桃等16个城市是三级中心城市。(2)区域尺度中,分别从武汉城市圈、环长株潭城市群和环鄱阳湖城市群三个区域展开城市中心性评价。从时序演化来看,武汉城市圈城市中心性差异最大,平均中心性和中心性差异都呈缓慢性上升趋势;环长株潭城市群城市平均中心性较高,平均中心性和中心性差异均呈现缓慢上升趋势;环鄱阳湖城市群城市平均中心性最低,呈现缓慢上升趋势,但其中心性差异较小且呈现逐渐缩小趋势。从空间分布来看,武汉城市圈、环长株潭城市群和环鄱阳湖城市群城市中心性分布均呈现“核心-边缘”结构,其中,武汉城市圈城市中心性存在两极分化现象,分布极不均衡;环长株潭城市群东部城市中心性远高于西部城市;环鄱阳湖城市群城市中心性相较于武汉城市圈和环长株潭城市群分布更为均衡,过渡平缓。(3)城市群尺度中,对长江中游城市群城市中心性评价,在时序演化上,其中心性差异总体呈现扩大趋势。在空间演化上,其中心性空间分布呈现离散化特征,中心城市处于“孤岛”状态,空间呈现武汉市和南昌市“双核分散”向武汉市、长沙市、南昌市“三核分散”的发展模式转变。(4)根据长江中游城市群城市中心性评价过程中存在的问题,从地区统筹发展,产业协同发展和服务共享共建三个角度提出了发展对策研究。
[Abstract]:The centrality of the city reflects the relative importance of a city providing services for other areas. This paper, based on the statistical data of the cities of the middle reaches of the Yangtze River, based on the statistical yearbook, uses entropy method and ArcGis spatial analysis to analyze the urban centrality of the urban agglomeration in 2005-2014 years, from the whole, the region and the city group three. The results showed that: (1) in the city scale, the city center status of Wuhan, Changsha and Nanchang was higher in the city center status evaluation. The city center status of Xiaogan City, Xiangtan city and Jingmen city was faster, and the city center status of Jingzhou city decreased rapidly. From the space change, the city center status of Jingzhou city decreased. As a result, Wuhan has become the first city of the middle reaches of the Yangtze River by virtue of its superior location advantages, strong economic strength and large science and education resources. The evaluation of the basic functions of the city has made the city's production functions, trade functions, information functions, traffic functions, financial functions, science and education functions, culture functions and medical functions from time to time. The functions of production, trade and transportation have been promoted obviously, and the functions of culture, medicine and finance have been promoted slowly. From the view of spatial change, the functions of Wuhan, Changsha and Nanchang cities are prominent and faster, and the basic functions of the cities are more fully developed, and the other cities are compared with them, and the city functions are compared. To evaluate the urban hierarchy, Wuhan and Changsha are the Central Center, 13 cities such as Nanchang and other cities are two central cities, and the 16 cities of Xiantao are three central cities. (2) in the regional scale, the urban centrality evaluation is carried out from the Wuhan city circle, the ring long Zhuzhou Xiangtan urban agglomeration and the ring Poyang Lake urban group. In terms of time series evolution, Wuhan city circle city has the largest centrality difference, the average centrality and centrality show a slow rising trend, the urban average centrality of the city group in the ring Chang Zhu Tan city group is higher, the average centrality and the central difference both show a slow rising trend, and the average centrality of the urban agglomeration in the ring Poyang Lake city is the lowest, showing the slowness. In terms of spatial distribution, the central distribution of Wuhan city circle, ring long Zhuzhou Xiangtan Urban Agglomeration and Poyang Lake urban agglomeration has a "core edge" structure, in which the urban centrality of Wuhan city circle is polarized, and the distribution is extremely uneven; The central nature of the eastern city group of Zhuzhou Xiangtan Urban Agglomeration is far higher than that of the western city, and the centrality of the urban agglomeration in the ring Poyang Lake city is more balanced than the Wuhan city circle and the ring Chang Zhuzhou Xiangtan Urban Agglomeration. (3) the central evaluation of the urban agglomeration in the middle reaches of the Yangtze River in the urban agglomeration scale, in the time sequence evolution, the heart difference is generally expanded. Trend. In space evolution, the spatial distribution of the heart is discretized, the central city is in the state of "isolated island", and the space presents the transformation of "double core dispersion" in Wuhan and Nanchang to Wuhan, Changsha and Nanchang "three nuclear decentralization". (4) according to the centrality evaluation process of urban agglomeration in the middle reaches of the Yangtze River From the three perspectives of regional coordinated development, industrial collaborative development and service sharing and co construction, the development countermeasures are put forward.
