摘要
都市圈一体化发展是指城市间相互联系,经济、社会、文化、自然等多方面协调发展,是都市圈发展的目标导向。本研究以郑州都市圈为研究区,基于2012—2021年夜间灯光数据,综合使用景观指数和景观形态学空间格局分析方法,从空间扩张与空间联系视角,系统评估了都市圈一体化进程,分析了研究区都市圈景观格局的时空变化,揭示了都市圈的时空扩张和联系模式。结果表明:2012—2021年,郑州都市圈面积逐年扩张,景观斑块数量不断增加,呈集聚现象;都市圈内呈现出稳定性、多方向协同发展趋势,非中心城市扩张贡献度逐年提升,各组成城市扩张方式从内部填充逐步向外部扩张转变;都市圈的联系规模逐年拓展,城市间联系加强,城际联系带、物质信息交流通道初见雏形,都市圈联系一体化网络逐渐形成;都市圈一体化规划为都市圈发展提供了积极指导作用,应继续充分发挥都市圈带动效应,注重郑州-开封同城化、郑州-许昌一体化建设,推动新乡、焦作形成新兴增长极,并促进区域协同发展,强化政策、经济、交通、信息等联系网络,形成多元化、一体化发展局面。
Metropolitan integration development refers to the interconnection between cities and the coordinated development of various aspects such as economy,society,culture,and nature,which is the goal of metropolitan area development.With the Zhengzhou metropolitan area as the research area and based on nighttime light data from 2012 to 2021,we comprehensively used landscape index and landscape morphology spatial pattern analysis methods,systematically evaluated the integration process of the metropolitan area from the perspective of spatial expansion and spatial connection,analyzed the spatiotemporal variations of the landscape pattern of the metropolitan area,and revealed the spatiotemporal expansion and connection patterns of the metropolitan area.The results showed that the area of the Zhengzhou metropolitan area expanded year by year from 2012 to 2021,with the number of landscape patches continuously increasing,showing an agglomeration phenomenon.In the metropolitan area,there was a trend towards stability and multi-directional coordinated growth.The contribution of non-central cities to expansion increased annually,while the expansion patterns of various constituent cities gradually shifted from internal filling to external expansion.The connection scale within the metropolitan area had been expanding annually,with enhanced intercity connections.Intercity connection belts and channels for material and information exchange were emerging,and the integrated network of urban agglomeration connections was gradually forming.Metropolitan integration planning provided positive guidance for the development of metropolitan areas.We should fully leverage the driving effects of metropolitan areas,pay attention to the integration of Zhengzhou-Kaifeng and Zhengzhou-Xuchang,promote the formation of emerging growth poles in Xinxiang and Jiaozuo,as well as regional coordinated development,strengthen the network of policies,economy,transportation,information,etc.,and form a diversified and integrated development situation.
