摘要：识别和分析城市物流中心的影响范围和交互强度,有利于优化物流要素的空间布局,对实现物流行业降本增效具有重要意义。本文首先分别利用空间句法和词向量理论,对引力模型中的综合实力参数和距离参数度量方法进行优化,将物流要素出行时对空间结构的主观感受和偏好规律,与物资供需端的空间分布形态相结合,实现了对城市物流中心的识别,及其引力势力范围的划分,然后在此基础上构建复杂网络,利用边权值呈现了物流中心间的空间交互强度,最终完成城市物流中心动静形态的画像分析。通过空间统计和实地调查验证发现:(1)从引力势力范围分布来看,郑州市物流业以市辖区为核心,东西南三向延伸的空间动静特征,与规划文件中重点支持的物流建设项目空间分布具有较高一致性,物资需求端与供给端的空间匹配程度较高;(2)从空间交互关系来看,除了物资的供需关系,区域空间可达性对物流要素空间分布也具有较大影响,通过基础设施和物流要素的规划建设,可以增强市辖区与周边县市的空间交互强度,带动城市产业升级,促进区域共同发展。
Identifying and analyzing the influence sphere and interaction intensity of urban logistics centers is conducive to optimizing the spatial distribution of logistics elements,which is of great significance to reduce costs and increase efficiency in the logistics industry.Firstly,this paper optimizes the measurement methods of comprehensive strength parameters and distance parameters in the gravity model by using the spatial syntax and word vector theory,combining the subjective feeling and preference law of logistics elements on the spatial structure with the spatial distribution form of the logistics supply and demand side,and realizes the identification of urban logistics center and the division of its gravity sphere of influence.Secondly,this paper constructs a complex network and presents the spatial interaction intensity between logistics centers by using chain weight.Finally,the dynamic and static forms of urban logistics centers are analyzed.Through spatial statistics and field investigation,it is found that:from the view of the distribution of the gravitational influence sphere,Zhengzhou's logistics industry has the spatial dynamic and static characteristics of taking the municipal district as the core and extending from the core to the east,west,and south.These characteristics are highly consistent with the spatial distribution of logistics-construction projects mainly supported in the planning documents.The space matching between the demand side and the supply side is very high.From the view of the spatial interaction intensity,in addition to the supply-demand relationship of materials,regional spatial accessibility also has a great influence on the spatial distribution of logistics elements.The planning and construction of infrastructure and logistics elements can enhance the spatial interaction between the core districts and surrounding areas,drive the upgrading of urban industries,and promote regional development.
