基于公路客流趋势的省域城市间关系与结构研究——以安徽省为例

Intercity Relationship and Structure of Anhui Province from the Perspective of Passenger Flow of Coach Travel

基于日常公路客流的城市间关系与结构研究是一种重要的省域空间结构研究方法。作为城市间人流交往的重要组成部分,日常公路客流从动态关系视角反映了城市间的功能结构,更为清晰地展现省域空间的内在关系特征。通过对公路客流替代数据的进一步精确化,全面分析了安徽省域城市间每日公路客流的强度特征与结构特征,主要结论为:①省域整体呈现单中心的结构特征,受省域中心城市合肥直接影响并紧密联系的城市有巢湖、六安和淮南,三者是构筑合肥都市圈的主体;②以芜湖、马鞍山、安庆、铜陵为主体的皖江城市带城市间联系紧密,是安徽省域经济发展和城镇化的重要载体,其影响和联系范围包括池州和宣城,其中芜湖、安庆是皖江城市带的枢纽城市;③皖北地区城市间关系较为薄弱、分散,阜阳-亳州、淮北-宿州以及蚌埠-淮南三对城市间联系较为紧密,是皖北3个重要的城市发展组团,其中淮南是皖北区域链接合肥都市圈的枢纽城市。

The analysis on intercity relationship and regional spatial structure from the perspective of passenger flow of long-distance coach travel is an important approach to provincial spatial structure studies.Daily passenger flow of long-distance coach travel is a significant part of passenger flow among cities which can reflect functional intercity relationships and reveal the inner-provincial spatial relationship clearly.Based on the daily passenger flow of long-distance coach travel,in this article,Anhui Province is taken as an example.The characteristics of intercity relationships and spatial structure of Anhui Province is explored.To examine the characteristics of intercity relationships and spatial structure of Anhui Province,the research data are analyzed from two aspects.1） The intensify characteristics of the intercity passenger flow.Passenger flow is graded according to the numerical size,then the passenger characteristics of traffic flow in different regions are analyzed in this article,especially focusing on relationships between the provincial capital（Hefei） and other cities in this province.2） The structural characteristics of intercity passenger flow.According to directions of the largest passenger flow and the second largest passenger flow,the overall trend and spatial structure of the daily population movements among cities are analyzed,and the provincial nodes in the urban network from the perspective of topological characteristics and the flow strength on the city level are examined in this article.The conclusions are as follows： 1） On the whole,Anhui Province presents a mono-center structure,and the inter-regional links between cities are relatively weak except the center city（Hefei）;Hefei affects and maintains frequent contact with Chaohu directly,Lu＇an and Huainan.There seems to be a high possibility that these three cities would become a major part of the metropolitan area of Hefei,the economic center and capital of Anhui Province.2） Wuhu,Ma＇anshan,Anqing and Tongling connect with each other tightly,and are the main constitutions of urban belt in Wanjiang,an important carrier of economic development and urbanization in Anhui Province,and further influence Chizhou and Xuancheng.3）Intercity relations are weak and scattered in the northern region of Anhui Province.The three pairs of cities—Fuyang and Bozhou,Huaibei and Suzhou,Bengbu and Huainan,are important urban groups in the northern Anhui Province.Each of them maintains a close contact within the urban group.And Huainan is the regional hub of northern Anhui Province.
