摘　　要：经济全球化时代,“流空间”成为配置资源的底层逻辑,各种功能要素的空间流动不断冲击与重塑城市间的联系,成为一体化空间网络的新机制和新动力。文章以西北地区51个地级及以上城市为研究单元,基于经济流、交通流和信息流,结合现实与虚拟视角分析多维要素流影响下的城市关联特征,运用赋值法构建综合折叠网络并划分城市等级,刻画区域空间发展格局。结果表明:(1)西北地区网络化特征明显,形成“一轴三区多中心”的网络格局,并在行政区约束和城市群引领下,初步形成6个凝聚子群。(2)受地理距离与行政边界影响,省区内联系强度大于省际,近域拓展大于远域扩张,大城市首先为本省带来发展红利,规模越大的城市跨省区正向溢出越强。(3)整体网络呈“核心—边缘”结构,核心区城市又呈“一二三四”布局,边缘区则呈“散点状”分布。经济流和交通流总量服从帕累托分布。经济流核心城市“以强带弱”与“强强联合”共存,在空间上形成组团结构;交通流联系轴线等级明显。普列流陇海—兰新沿线城市表现出“点—轴”式空间格局,快列流“强强联合”多而“抱团取暖”不足,“马太效应”显著;公路流则呈现出明显的“向心集聚”态势;信息流具有广覆盖性和强渗透性,表现出“扁平层级+核心引领”的兼具稳定性和流动性的结构特点。The"Flow Space"has become the underlying logic of resource allocation in the economic globalization era.The spatial flow of various elements has constantly impacted and reshaped the relationship between cities,becoming a new mechanism and driving force for the integrated spatial network.Based on the economic flow,traffic flow and information flow,combined with reality and virtual perspective,this paper analyzes the urban linkage characteristics under the influence of multi-dimensional flow of 51 cities in Northwest China,and further takes the assignment method to construct a comprehensive folding network and divide the urban hierarchy,and depict the regional spatial development pattern.The results are as follows:1)The network characteristics of the urban linkage are obvious in Northwest China,which shows a network pattern of"one axis,three zones and multiple centers",and initially forms six cohesive subgroups under the constraints of administrative regions and the guidance of urban agglomeration.2)Affected by geographical distance and administrative boundary,intra-provincial connection is greater than inter-provincial,Near-domain expansion is greater than far-domain,big cities first brings development benefits to its province,The larger the scale of cities,the more obvious the positive spillover across provinces.3)The"core-edge"structure of the overall network is obvious,and the cities in the core area form the distribution pattern of"one strong-core city,two core cities,three sub-central cities and four important cities",and the urban linkage shows the scattered distribution in the edge area.Economic flow and traffic flow obey the Pareto distribution.The economic flow forms a group structure in space,Its core cities are both connected with other core nodes and edge nodes.The grade of traffic flow connection axis is obvious.In the ordinary train flow,the cities along the lines of Lanzhou-Lianyungang and Lanzhou-Xinjiang show the"point-axis"spatial pattern.The core cities produce high-density connections with othe
