中国大都市区的界定和发展研究——基于第六次人口普查数据的研究

借鉴都市区概念,采用“六普”城乡统计口径,以区、县为基本单元,利用人口密度、城镇化率等指标界定了128个大都市区。其次,对2000~2010年中国大都市区人口规模结构和空间分布的特征及变动进行了研究。从规模结构上看,以大都市区人口表征的中国城市规模分布符合位序规模法则,且属于较为分散的类型,但斜率q从2000年的0.787提高到2010年的0.891,显示都市区的规模分布趋向集聚,且高等级都市区仍有一定发展空间。从空间分布上看,东部是中国大都市区的主要分布地带,且人口有进一步向该地区集聚的趋势,并形成了三大都市区连绵地区;中部地区都市区数量增加较多,但人口比重有所下降;西部地区大都市区发展最为滞后,都市区极化现象十分突出。最后就中国大都市区的发展提出了建议。

The Definition and Development of Metropolitan Areas in China Based on the Data from the 6th National Census

The cities in China are the administrative regions of different scales, and they are actually a kind of the city-region. So, the population size of a city in China can not represent the city’s real urban size. Based the concept of metropolitan area and the urban-rural definition from the 6th National Census, and adopted the related indices of population density and urbanization rate at the same time, the article firstly identified 128 metropolitan areas of China in 2010. Secondly, the article studied the characteristics and change of population size and spatial distribution of metropolitan areas of China. Structurally, the scale of population size in urban China obeys the rank-size rule, while the index of q rose from 0.787 to 0.891 in past 10 years which indicated the concentration of metropolitan system in China; nevertheless, the model of mega metropolitan areas has been seen since 2000, and there remains to be some developing space for those advanced metropolitans. Spatially, most metropolitan areas concentrate in the Eastern China, and three metropolitan interlocking regions have been emerging; the number of metropolitan areas is increasing in Middle China, but the population proportion accounted for the total population of metropolitan areas is lower; the development of metropolitan areas in the Western China lags behind other areas, with a characteristics of polarization. Lastly, the paper put forwards some suggestions.
