黄河中下游省区城市联系的空间格局分析——基于铁路、公路客运班次

Spatial Pattern of Urban Relationship in the Middle and Lower Yellow River Areas——Based on coach operations of railway and highway

以黄河中下游省区66个地级市为基本研究对象,基于铁路、公路客运班次数据,利用GIS空间分析中的OD网络分析方法揭示黄河中下游地区城际联系的空间格局特征。研究发现,研究区域城市的空间联系总体上分布不均,在河南、山东两省内城市对之间的空间联系密集,呈现出向中心城市集中的特征;铁路客运联系强度较大的城市对主要集中在主要铁路干线上,在陇海-兰新线与京广线之间,形成了"一纵一横"格局,公路客运联系较强的轴线主要围绕各省的核心城市。省内城市间的空间联系密集,而跨省城市间的空间联系稀疏,跨区联系有待加强。研究政策启示在于,未来需要关注轴带发展、多层次空间组织及城市群空间互动的国土空间规划战略。

Taking 66 prefecture-level cities in the middle and lower reaches of the Yellow River Basin as the basic research object,using the GIS spatial analysis method of O-D network to analyze the spatial pattern of the inter-city relationship in the middle and lower reaches of the Yellow River.The results show that,the spatial connection of cities in the study area is uneven in general,and the spatial connections between urban pairs in Henan and Shandong provinces are dense,and the connections concentrate to center cities;the city pairs with strong railway passenger transport connection intensity are mainly concentrated on the main railway trunk lines,and a“one vertical and one horizontal”pattern is formed between Longhai-Lanxin line and Beijing-Guangzhou line and relates to the“five vertical and three horizontal”pattern of national railway,and the lines with strong road passenger transport connection mainly revolve around the core cities of each province.The spatial relationship between cities within the province is dense,while that inter-city relationship across provinces is sparse,so the regional relationship needs to be strengthened.The paper's policy implications are further needs to focus on spatial planning of national land of axis development,multilevel spatial organization,and interactions of urban agglomerations.
