中原经济区城市体系空间组织

Spatial organization of urban system in Central Plains Economic Region

新型城镇化是引领中原经济区"三化"协调发展的重要切入点,而城市体系空间组织又是支撑新型城镇化的主要载体。依据空间组织的基本理论,采用多种空间分析手段,分析了中原经济区城市体系的空间组织路径,结论如下:①通过规模实力、综合实力评价模型计算中原经济区30个省辖市的空间组织等级,结合空间组织的均衡原则,确定以郑州为核心城市,洛阳、邯郸、信阳和商丘为区域中心城市,晋城、安阳、南阳、淮北为区域性次中心城市的等级体系;②应用分形理论、圈层分析、缓冲区分析、城市相互作用模型等方法分析发现,中原经济区具备以郑州为核心的圈层式、轴带状、核心板块网络化、组团分区的组织基础;③结合空间组织的等级层次和现实基础,提出中原经济区空间组织的"中心带动、圈层推动、轴带组织、核心板块网络化、组团分片"的模式选择与路径取向。

Construction of economic region has become an inevitable trend as a result of the development of the country＇s multicentered economies, which is also an important support for the strategy of spatial development in each province. The State Council＇s guidance on speeding up the construction of Central Plains Economic Region （CPER）, issued on September 28, 2011, clearly proposed that coordinating urbanization, industrialization and ag- ricultural modernization is the main strategic theme, and optimizing urban system spatial layout and coordinat- ing urban-rural development are the major tasks. Therefore, it is extremely important to integrate urban systems＇ spatial structures in order to achieve the coordinated development between growth pole and growth plate, center areas and peripheral areas, in CPER. In this paper, based on the theory of regional urban system organization op- timization in urban geography, and using the methods of a spatial evaluation model, we did an in-depth analysis on the roadmap of the spatial organization of CPER. The results are as follows. （1） By the evaluation models of the scale strength and comprehensive development strength, the spatial organization levels of the 30 cities in CPER are calculated. Based on the principle of proportionality of spatial distribution and the evaluation results, Zbengzhou is identified as the core city of CPER; Luoyang, Handan, Xinyang and Shangqiu are considered as the regional central cities; Jincheng, Anyang city, Nanyang and Huaibei are the second-level regional central cit- ies; other 21 cites are the local central cities; 201 counties are basic cities for promoting the development of rural areas. （2） Depending on the evaluation models of the spatial organization, such as fractal theory, buffer analysis, circle analysis, urban interaction model, and other quantitative methods, CPER exhibits basic spatial organiza- tion characteristics such as poly-center status, spheres radiation, regional group development, network trend. At the same time, the advantages and disadvantages of different urban system spatial organizations in CPER are dis- cussed. （3） Based on the results of spatial organization evaluation models, combined with the basic model of ur- ban spatial combination such as radial growth patterns of mononuclear, multicore balanced and unbalanced growth models, we proposed a spatial integration model for CPER, including one growth pole （Zhengzhou）, four circle-layer, five regional cities, four sub-regional cites, five urban coordination region, and seven axis, and sug- gest that strategies are selected based on specific spatial integration models. From the perspective of best organi- zation models and developmental trend, spatial organization of urban system approaches to promoting healthy development of new urbanization in CPER should be mononuclear unbalanced growth from the center Zheng- zbou, sphere extending from Zhengbian metropolitan area to the outer layer, network development of core growth plate of urban agglomeration of Central Plains, five urban partitions including core growth plate, north- ern coordinated region, western coordinated region, southern coordinated region and eastern coordinated region, following the pattern of ＂junction cites（dot） ＋ axis （line） ＋ functional partition （side） ＋ network organization＂. In summary, based on the analyses, we proposed the development methods and roadmaps of the spatial organiza- tion, which may predict the future direction of urban system spatial integration in CPER and can also provide support for the coordinated development of new urbanization, new industrialization and new agricultural mod- ernization.
