摘　　要：基于腾讯人口迁徙大数据,采用复杂网络分析方法,对黄河流域城市网络联系的区域差异性和空间指向性进行了系统的分析。结果表明:①流域内城市网络密度较低,平均路径较长,与其"承南接北"的区域地位不相匹配。②形成以陇海线、下游黄河干流和包海高铁为轴线的骨干网络,核心-边缘结构突出。③流域内-外联系网络形成两大(郑州和西安)、一小(济南)三个核心,高等级网络以三者为核心节点向域外辐射。强集散能力节点城市集中在"陇海线-下游黄河干流"一线。域外主要联系方向为珠三角和长三角地区。④流域内部网络和内-外联系网络相比,"陇海线-下游黄河干流"和包海高铁一线以东城市优势更为凸显。⑤流域不同地区网络联系的空间指向性差异明显。流域内部联系多指向省会城市,内-外联系的空间指向上存在明显的上中下游分异。The Yellow River Basin is a hub region in the south and north of China.With the gradual implementation of the"Yellow River Basin Ecological Protection and High Quality Development Strategy",the flow of factors will inevitably be accelerated and the formation of city networks will be promoted.Based on Tencent’s big data of population migration,this paper uses a complex network analysis method to systematically analyze the regional differences and spatial directivity of city network connections in the Yellow River Basin.The purpose is to identify the spatial and temporal patterns of internal and external connections in the Yellow River Basin.Provide decision-making reference for high-quality development of the basin.The results show that:1)The city network density of the basin is low,and the average path length is long,which does not match its regional status of"contact north and south".2)Inside the basin,a backbone network is formed with the"Longhai Railway-the main stream of the lower Yellow River"and the Baohai Highspeed Railway as the axis,and the core-periphery structure is prominent.3)The internal and external network of the basin forms two major(Zhengzhou and Xi’an)and one small core cities(Jinan),and the high-level network uses these as the core nodes to radiate out of the domain.The city nodes with strong distributed capacity are concentrated on the"Longhai Railway-the main stream of the lower Yellow River".The main contact directions outside the region are the Pearl River Delta and Yangtze River Delta.4)Compared with the internal and external networks of the basin,the advantages of the cities along the"Longhai Railway-the main stream of the lower Yellow River"and the east of the Baohai High Speed Railway are more prominent.5)The spatial orientation of network connections in different regions of the basin has obvious differences.The internal connection networks of various provinces point to the provincial capital,and the spatial orientation of the internal-external connection networks has obvious upper
