| 摘 要： | 对中心城市的选择与培育是欠发达地区区域发展必须解决的关键问题。在江西省社会经济数据及交通地理数据支持下，以2000、2005及2010年为时间断面，采用Kernel城市空间密度分析和“自下而上”的城市等级与腹地划分方法，从城市规模结构、等级结构与腹地结构3个角度对赣南原中央苏区城市体系演变进行研究，在此基础上识别出中心城市，并提出培育路径。研究结果表明，2000―2010年，赣南原中央苏区的城市人口规模正处于加速扩张阶段。城市规模空间结构呈现显著的核心―边缘特征，以赣州、吉安、瑞金、南城为中心的城市人口集聚核心区已经显现。以赣州、吉安、瑞金、南城为中心的城镇密集区释放出了显著的空间集聚效应，成为推进苏区城市化进程的重要增长极。苏区的城市等级可划分为3个等级，赣州、吉安、瑞金和南城一直是苏区最具辐射力的一级城市，其在城镇体系中的高等级城市地位已经比较稳固。在城市腹地结构演变上，尽管二级城市的腹地范围持续变动，但赣州、吉安、瑞金和南城4个一级城市的腹地范围始终保持稳定，这与其在城市等级中的稳定性高度吻合。研究认为，应选取赣州作为苏区主中心城市，选取吉安、瑞金、南城作为次中心城市；应从优化城市职能分工、壮大城市产业、做大城市城区、优化交通网络与加强制度创新等方面对中心城市进行培育。

| Abstract: | In some undeveloped regions of China, the relationship between central cities and their jurisdictional areas is usually described as “a pony drags a cart”, and the radiation and promotion functions of the central cities for their jurisdictional areas are limited. Hence, the selection and cultivation of central cities are the key problem that the less developed regions must face and solve. Taking 2000, 2005 and 2010 as three time sections, with the social-economic statistics and traffic data of Jiangxi Province, this paper analyzes the evolution of urban system in the former Central Soviet Area in the south of Jiangxi Province from three aspects, namely, urban scale, hierarchy and hinterland structures, by Kernel density of urban space and “bottom-up” urban level and hinterland division methods. On that basis, the central cities in the areas are identified and their cultivation paths are put forward. Firstly, simulate the evolution of spatial structure of cities’ and towns’ scale by using Kernel density of urban space method, and then identify the concentration areas in the former Central Soviet Area. Secondly, utilize accessibility analysis to acquire the shortest time distance between each two cities/towns in 39 county-level administrative regions, then measure the intercity space contact intensity with the help of gravity model which takes time distance as model parameter. Finally, mark out the levels and hinterlands of cities in the Area by using the “bottom-up” division method. The results show that: during 2000-2010, the population scale of cities in the Area was acceleratingly expanded, and its spatial structure presented a significant core-edge feature. Therefore, core areas of urban agglomeration concentrated in Ganzhou, Ji’an, Ruijin and Nancheng appeared and showed significant spatial agglomeration effects, and became the essential growth poles promoting the urbanization of the Area. The levels of cities and towns in the Area can be classified into three grades, that is, Ganzhou, Ji’an, Ruijin and Nancheng have always been the first-grade cities, and their high-grade statues in cities’ and towns’ system are relatively stable. When it comes to the evolution of urban hinterlands, the hinterlands of second-grade cities continue to change, but the hinterlands of the first-grade cities keep stable all the time which are consistent highly with the stability of the four cities’ level. The study suggests that Ganzhou could be selected as the central city, while Ji’an, Ruijin and Nancheng as the secondary central cities, so lastly forms a “1+3” cities’ group. Taking the practical situation into account, we should foster central cities from several aspects, such as expanding city industries and city districts, optimizing the division of city function and transportation network, strengthening the institutional innovation and so forth. |
