摘　　要：城市群作为当前推动我国新型城镇化战略的主体形态,其高质量发展的关键在于规模结构是否合理、空间结构组织是否优化及城市间联系的密切程度。基于豪斯道夫维数、空间聚集维数及空间关联维数对中原城市群发展质量进行评价。结果显示:(1)中原城市群规模结构质量较低,表现为超大城市和Ⅰ型大城市缺失,中间位序城市较少,小城市数量较多,规模较低,城市规模结构不尽合理;(2)中原城市群空间集聚质量较高,表现为城市分布密度以郑州为中心向四周递减,集聚趋势明显,越向外围中心城市对其吸引力越弱;(3)中原城市群空间结构质量较高,表现为城市空间分布较为均衡,各城市间交通网络通达性较好,空间联系比较密切,城市布局具有明显的交通指向型。Urban agglomeration is the main form of promoting the new urbanization strategy in our country,and the keys to its high-quality development lie in whether the scale structure is reasonable or not,whether the spatial structure organization is optimized or not,and the close degree of urban connections.Based on Hausdorff dimension,spatial aggregation dimension and spatial correlation dimension,the development quality of Central Plains Urban Agglomeration(CPUA)is evaluated.The results show that:(1)the scale structure quality of CPUA is low,which is characterized by the lack of megacities and type-I metropolises,fewer middle sequence cities,more small cities,lower scale,and unreasonable city scale structure;(2)the spatial agglomeration quality of CPUA is higher,showing that the urban distribution density decreases from Zhengzhou as the center to the periphery,and the agglomeration trend is obvious;(3)the spatial structure quality of CPUA is high,which is manifested as balanced urban spatial distribution,good transportation network accessibility among cities,close spatial connections,and obvious traffic orientation in urban layout.
