江浙沪地区客货运量位序-规模分布特征及影响因素

Distribution Characteristics and Influencing Factors of Passenger and Freight Volume in Jiangsu,Zhejiang and Shanghai

利用位序-规模法则刻画1985年、1995年、2005年和2017年江浙沪地区客货运量的位序-规模分布特征,同时运用ArcGIS 10.4软件对该地区客货运量空间分布及重心移动轨迹进行可视化表达并对其影响因素进行探讨。结果表明:(1)江浙沪地区客货运量在空间分布上符合位序-规模法则并呈现出西北—东南走向。(2)江浙沪地区客货运量规模空间分布均经历了不均衡→均衡→相对集中→相对均衡的发展过程。(3)经济发展水平和交通基础设施对客货运量位序-规模分布有重要影响,人口管理制度、人口规模对客运量位序-规模分布变化具有直接影响,而城市产业结构与货运量位序-规模分布变化则更为密切。

In this paper,the rank-scale distribution characteristics of passenger and freight volume in Jiangsu,Zhejiang and Shanghai in 1985,1995,2005 and 2017 are described by using the rank-size rule.At the same time,the spatial distribution of passenger and freight volume and the moving track of center of gravity are visualized by using ArcGIS 10.4 software,and the influencing factors are discussed.The results show that:(1)The spatial distribution of passenger and freight volume in Jiangsu,Zhejiang and Shanghai is in accordance with the law of order-scale and shows a northwest-southeast trend.(2)The spatial distribution of passenger and freight volume in Jiangsu,Zhejiang and Shanghai shows a process of unbalanced→balanced→relatively concentrated→relatively balanced development.(3)The level of economic development and transportation infrastructure have an important impact on the order scale distribution of passenger and freight traffic volume,while the population management system and population scale have a direct impact on the order scale distribution change of passenger traffic volume,while the urban industrial structure and freight volume order scale distribution change are more closely related.
