【摘要】：交通是连接区域的重要纽带,承接各种社会资源的流转,是促进区域经济社会发展的重要的因素。作为后发展地区的广西壮族自治区,经济社会正处于快速发展时期,交通网络对广西城市空间的形成与发展有着重要深远的影响,尤以承担着大多数客流以及货流的公路运输和铁路运输为甚。选取以公路和铁路为代表的陆路运输方式为研究对象,运用文献研究法、数理分析法、比较研究法、定量分析和定性分析结合法等方法,从《广西统计年鉴》(2016)中收集广西常住人口数、地区生产总值、固定资产投资额、社会消费零售总额等八项指标的相关数据,从电子网络地图中收集县级以上的公路交通网络以及铁路交通网络,并与最新地图进行校正,对交通网络的相关数据进行矢量化及赋值,利用加权平均旅行时间模型、基于时间矩阵的通达性模型以及潜力模型这三种模型,选择广西87个县域作为采样节点城市(镇),分别计算出它们的加权平均旅行时间通达指数、加权时间通达指数、潜力通达指数,将指数通过空间插值法变成可视化结果,对广西区内的交通网络通达性进行了研究对比。研究结果表明:在铁路交通网络方面,节点城市的通达性具有高速铁路的指向性,在公路交通网络方面,则没有明显的指向性,反而受到广西区内交通网络上的地理位置影响显著,在综合交通网络方面,则是呈现了以来宾市、贵港市以及南宁市为较优通达性的格局。建议对广西区内产业发展中心适时合理调整,强化来宾市作为柳州市工业产业的承接地以及辐射全区的综合性商贸物流中心的定位;加强广西北部湾经济区城市组团尤其是北海市的发展;加快桂西地区的交通网络的完善以利于加快老少山穷地区发展,进而实现广西区域协调发展。
[Abstract]:Transportation is an important link connecting the region, and it is an important factor to promote the development of regional economy and society to undertake the circulation of various social resources. As the post-development area of Guangxi Zhuang Autonomous region, the economy and society are in a period of rapid development, and the traffic network has an important and far-reaching impact on the formation and development of urban space in Guangxi. This is especially true for road and rail transport, which carries most of the passenger and freight flows. In this paper, the road and railway transportation mode is chosen as the research object, and the methods of literature research, mathematical analysis, comparative research, quantitative analysis and qualitative analysis are used to combine the methods, such as literature research method, mathematical analysis method, comparative research method, quantitative analysis method and qualitative analysis method, etc. From the Statistical Yearbook of Guangxi (2016), collect the relevant data of eight indexes, such as the number of resident population, regional gross domestic product, investment in fixed assets, total retail sales of social consumption, etc. The road traffic network and railway traffic network above the county level are collected from the electronic network map, and calibrated with the latest map, the relevant data of the traffic network are vectorized and assigned, and the weighted average travel time model is used. Based on the three models of time matrix accessibility model and potential model, 87 counties of Guangxi are selected as sampling node cities (towns), and their weighted average travel time access index and weighted time access index are calculated respectively. The index of potential accessibility is transformed into a visual result by spatial interpolation, and the accessibility of transportation network in Guangxi is studied and compared. The results show that: in the aspect of railway transportation network, the accessibility of node cities has the directivity of high-speed railway, but in the aspect of highway traffic network, it has no obvious directivity. On the contrary, it is influenced by the geographical location of the transportation network in Guangxi. In the aspect of comprehensive transportation network, the pattern of Laibin City, Guigang City and Nanning City is presented as the better accessibility. It is suggested that the industrial development center in Guangxi should be readjusted in a timely and reasonable manner to strengthen the positioning of Laibin as the undertaking place of the industrial industry of Liuzhou and the comprehensive trade and logistics center of the whole region. Strengthening the development of Guangxi Beibu Gulf Economic Zone, especially Beihai City, and speeding up the improvement of the traffic network in the west of Guangxi in order to accelerate the development of the old and young mountain areas and poor areas, and then realize the coordinated development of Guangxi region.
