基于航线数据的城市跨区域发展研究——以郑州市为例

Research on Urban Cross-regional Development Based on Airline Data: A Case Study of Zhengzhou

基于中国内地城市航线数据及现有的城市间网络关系和城市群落分布特点,根据相关系数阐述航线密度、航线连接度、运输能力、活力指数等因子的内涵及关系,对城市跨区域发展进行分析,丰富以中心城市为核心向周围辐射的城市群的发展模式并优化城市发展格局。此外,研究利用可视手段直观展现地理空间现象,以郑州市为例进行验证。结果表明:(1)城市间距离与航线密度不相关,利用航线数据研究城市跨区域发展是合理的;(2)东西部地区发展水平存在差距,通过城市跨区域发展,推动西部地区发展,弥补城市群结构的不足,实现优劣互补;(3)城市跨区域发展配合时间因素,能在时空关联角度上辅助城市规划。

Based on the data of urban airlines in China's Mainland,the existing intercity network relationship and the distribution characteristics of urban agglomeration,this research analyzes the urban cross-regional development,enriches the developmental model of urban agglomeration with the central city at its core to the surrounding radiation and optimizes the urban development pattern according to connotation and relationship of the factors such as airline density,airline connectivity,transport capacity,vitality index and so on.In addition,this research presents the geospatial phenomenon by visualization means,takes Zhengzhou for instance to verify the experiment and draws the following conclusions:①The distance between cities is not related to the route density,so it is reasonable to use the airline data to study the cross-regional development of cities;②There is a gap in the development level between the eastern and western regions,so cross-regional development can promote the development of the western region,make up for the deficiency of urban agglomeration structure and realize the complementary advantages and disadvantages;③The urban cross-regional development combined with time factor can support urban planning in the perspective of space-time correlation.
