【摘要】 从城市综合实力和绝对联系强度、相对联系强度两方面对引力模型进行了改进,利用改进的模型评价黄河下游沿岸18个地市2012—2018年的城市空间联系特征,分析其空间格局及演变。结果表明:黄河下游沿岸城市空间联系呈现出以济南、郑州为核心的城市组团特征,空间结构上呈现出"双核心四中心",进而可以将城市空间格局划分为五大组团:济南城市组团、郑州城市组团、安鹤濮城市组团、滨东城市组团和荷商城市组团。各组团间发展差异较大,亟需找准发展路径,实现差异化发展。更多还原

【Abstract】 The gravity model was improved from the aspects of city comprehensive strength and absolute and relative strength of connection. The improved gravity model is used to evaluate the urban spatial connection characteristics of18 cities along the lower reaches of Yellow River from 2012 to 2018. Besides, the spatial pattern and evolution of these cities were further analyzed at the same time. The research results indicated that the spatial connection of these cities along the lower reaches of Yellow River shows the characteristics of urban cluster with Jinan and Zhengzhou as the core;it also presents the spatial structure of “double core and four centers”. Then the urban spatial pattern can be divided into five major groups: Jinan urban cooperation groups, Zhengzhou urban cooperation groups, Anhepu urban cooperation groups, Bindong urban cooperation groups, and Heshang urban cooperation groups. Since development way of each group is quite different, it is urgent to find the right way to realize differentiated development of each group.更多还原
