【摘要】：交通运输是生产要素及产品等空间位移得以实现的主要载体,相对完善的交通运输体系能够促进区域经济联系,提升区域集聚作用,增强规模经济效益,提高区域的开放程度。交通基础设施的建设对区域内经济的规模、结构以及空间布局有着反馈和引导的作用,诱导交通优势能够成为经济优势促进地区发展。本文以兰新高铁为例,对比分析高铁通车前后沿线城市相对影响力及可达性的变化情况,并进一步确定城市场的强度及范围。首先,借鉴国内外已有的研究成果和理论,对交通基础设施及高速铁路建设与节点城市发展的相互关系进行梳理和阐述,明确了本文研究的切入点,从而建立了对本文定性分析的逻辑框架。然后,进行高铁的建设运营对沿线节点城市产生聚散效应的理论分析,从不同角度出发,多方面参照各种影响因素对高铁在城市发展中产生的效应、聚散的方式以及聚散的时空特性进行定性分析,提出集聚与扩散虽相互对立但始终并存,二者在不同社会发展阶段中发挥不同作用。其次,通过借鉴物理学中“场”的思想,建立了改进场模型。对高铁沿线节点城市的影响力指数的测算,选取了7个大方面15个指标形成指标体系,采用熵值法确认各项指标权重,然后计算出影响力指数。选取基于交通时间成本的测度方法,以GIS技术为实现方式,确定节点城市可达性的强度。在对城市影响力指数构建和区域可达性进行测算的基础上完成对传统场模型的改进。最后,以兰新高铁为具体研究实例,分析了兰新高铁的线路情况、建设意义及必要性,选取2008年和2015年为时间断面,选取兰新高铁沿线7个人口较多的地级市作为研究节点城市,运用建立的改进场模型,基于熵值法确认各年份各节点城市影响力指数,以ArcGIS软件为平台,测算节点城市可达性,进而得到各城市场强变化情况,并对研究区域内各城市的发展状况和演变格局进行分析。本文基于对GIS平台的综合运用测度兰新高铁沿线节点城市聚散效应,方法简单、可操作性强、结果直观。充分考虑到城市自身的综合规模与城市可达性对节点城市聚散效应的双重影响,与城市发展的实际情况较为贴合,较好地实现了高速铁路对节点城市聚散效应的定量分析。
[Abstract]:Transportation is the main carrier for the realization of spatial displacement such as production factors and products. A relatively perfect transportation system can promote regional economic ties, enhance regional agglomeration, enhance scale economic benefits, and improve the degree of regional openness. The construction of transportation infrastructure has the function of feedback and guidance to the scale, structure and spatial distribution of the regional economy, and inducing the traffic advantage can become the economic advantage to promote the development of the region. Taking Lanxin high-speed railway as an example, this paper compares and analyzes the changes of relative influence and accessibility of cities along the route before and after the opening of high-speed rail, and further determines the intensity and scope of the city market. First of all, referring to the existing research results and theories at home and abroad, the relationship between traffic infrastructure and high-speed railway construction and the development of node cities is combed and expounded, and the breakthrough point of this study is clarified. Thus, the logical framework of qualitative analysis is established. Then, the construction and operation of high-speed rail to the urban node along the theoretical analysis of the convergence effect, from different angles, many aspects of the various factors affecting the high-speed rail in urban development effects, Based on the qualitative analysis of the ways of aggregation and the space-time characteristics of aggregation, it is proposed that the two play different roles in different stages of social development, although they are opposite to each other but coexist all the time. Secondly, an improved field model is established by referring to the idea of "field" in physics. According to the calculation of the influence index of the cities with nodes along the high-speed rail line, 15 indexes in 7 major areas are selected to form an index system, and the entropy method is used to confirm the weight of each index, and then the influence index is calculated. Based on the measurement method of transportation time cost, the intensity of reachability of node cities is determined by GIS technology. Based on the measurement of urban influence index and regional accessibility, the traditional field model is improved. Finally, taking Lanxin high-speed railway as a concrete research example, this paper analyzes the line situation, construction significance and necessity of Lanxin high-speed railway, and selects 2008 and 2015 as time section. Seven prefecture-level cities with large population along Lanxin high-speed railway line are selected as the research node cities. The improved field model is used to determine the influence index of each node city in each year based on entropy method. The accessibility of node cities is calculated on the platform of ArcGIS software. Then the change of field strength of each city is obtained, and the development situation and evolution pattern of each city in the study area are analyzed. Based on the comprehensive application of GIS platform, this paper measures the effect of urban convergence along Lanxin high-speed rail line. The method is simple, operable, and the result is intuitionistic. Considering the dual influence of the comprehensive scale of the city itself and the accessibility of the city on the urban convergence and dispersion effect of the node city, and in accordance with the actual situation of the urban development, the quantitative analysis of the effect of high-speed railway on the node city convergence effect is well realized.
