摘要： 在中原城市群的整合发展中,建设结构完善、功能强大的城市体系是一项特殊重要的历史任务,而城市体系的"结构优化"更是首当其冲的必须妥善解决的关键问题。城市体系结构优化的实质是:通过政府的宏观规划调控和城市群内各地域单元的整合,实现不同等级、不同规模、不同职能的城市在空间平台上的高度和谐,从而实现城市体系整体实力的提升,最终实现城市群的可持续发展。基于城市群整合发展的中原地区城市体系结构优化的主要内容是:第一,用"城市中心性强度"法来划分中原城市群地区所有城市的等级,进而构建出4个等级城市体系的层次。第二,采用灰色系统GM(1 ,1)模型并根据人口的机械增长基础,求出各城市2020年非农业人口的优化指标。第三,运用纳尔逊(H.J.Nelson)统计分析原理和方法,确定各城市的优势职能、突出职能以及重点发展行业。第四,构建了"两圈、双核、四带、一个三角"的城市体系空间布局和功能发挥的整体框架。

Abstract: Zhongyuan urban agglomeration is an important spatial platform advancing "rise of middle of China", also the indisputable main item realizing "rise of the Zhongyuan Plains" in Henan Province. In the integrated development of Zhongyuan urban agglomeration, the construction of the urban system with perfect structure and formidable function is a special important historic task, and the structure optimization of the urban system is a key problem that should be solved properly. The essence of the structure optimization of the urban system is, through government's macroscopic plan regulation and urban agglomeration's integration, to realize the high degree of harmony of the cities with different ranks, different scales and different functions in the spatial platform, thus realizing the promotion of the urban system's overall strength, and finally realizing the sustainable development of urban agglomeration. The primary content of the structure optimization of the urban system in Zhongyuan urban agglomeration is: the rank level optimization, the scale sequence optimization, the function type optimization and the spatial layout optimization. First, the rank level optimization of the urban system. This article uses the law of "city centricity intensity" to divide the rank of all cities in Zhongyuan urban agglomeration, and then constructs four rank levels of the urban system. Second, the scale sequence optimization of the urban system. This article uses the gray system GM(1,1) model, and, according to the status, economic development situation as well as population machinery growth foundation of different cities, to extract the optimized target of the non-agricultural population of various cities in 2020. Third, the function type optimization of the urban system. This article incorporates industries into 8 departments reflecting city function activities, uses Nelson's(H.J.Nelson) statistical analysis principle and method to determine the superiority functions, the prominent functions, the function intensities and the specialization indexes of the cities in Zhongyuan urban agglomeration. Fourth, the spatial layout optimization of the urban system. Around 2020, Zhongyuan urban agglomeration will form an overall pattern of city space layout and function display: "two circles, double nucleuses, four belts and one triangle".

Key words: Zhongyuan urban agglomeration, integrated development, urban system, structure optimization
