摘要
大都市区是中国城镇化的重要空间载体,是推动城市群发展和新型城镇化进程的主要空间形态。基于已有“五普”“六普”相关研究,利用“七普”数据,采用城镇化率、人口密度、人口数量等指标,选择位序-规模法则、首位度指数等方法,识别大都市区空间范围,分析大都市区新近发展及演化特征。结果表明:(1)总体来看,2020年全国有174个大都市区,总人口为5.8亿。2020年大都市区数量较2000年增加57个,较2010年增加46个;人口比2000年增加3.81亿,比2010年增加2.61亿。(2)从规模来看,2000—2020年不同规模大都市区数量逐渐由金字塔型向橄榄型演变,但人口数量倒金字塔结构愈发增强。大都市区首位分布不明显,更加符合位序-规模分布。(3)从空间分布特征来看,2000—2020年大都市区东多西少的空间梯度分异格局基本稳定,并逐渐形成“两横三纵”的空间分布格局,且基本包含于城市群规划空间范围内。
Metropolitan area is an important geographical space of Chinese urbanization,and the basic spatial form to promote the development of urban agglomeration and new urbanization.On the basis of previous studies which was based on the fifth national population census and the sixth national population census,the study uses data of the seventh national population census,adopts indicators such as urbanization rate,population density and population number,selects the rank-size rule and primacy index to identify the spatial scope and analyzes recent development as well as evolution characteristics of Chinese metropolitan area.The main conclusions are as follows:(1)Overall,there are 174 metropolitan areas with a total population of 580 million in 2020.Compared to 2000 and 2010,the number of metropolitan areas respectively increased by 57 and 46 and the population respectively increased by 381 million and 261 million.(2)In terms of size,the number of metropolitan areas of different sizes has gradually changed from the pyramid structure to olive structure,but the inverted pyramid structure of its population has gradually apparent during the study period.The primary distribution of metropolitan areas isn't obvious,which is more in line with the rank-size distribution.(3)From the perspective of spatial distribution characteristics,the spatial gradient pattern of the metropolitan area with more east and less west is basically stable during the study period.And the spatial distribution of metropolitan areas gradually shows a pattern of“two horizontal and three vertical axes”.Metropolitan area basically included in the spatial scope of agglomeration planning.
