摘要:
在成渝双城经济圈的建设中,成渝高铁 作为一体化发展的重要驱动,给沿线中小城市带 来了新的发展机遇。同时高铁站区作为城市间与 城市内联系的关键区域,对促进城市群经济联 动有重要意义。然而却普遍存在定位不清、开发 缓慢、活力不足等问题。研究通过多源时空数据 分析,从发展模式、发展速度与功能定位3个方 面,探寻站区要素时空演化特征及相互影响关 系,并依据点轴辐射模式与空间价值,提出增强 交通可达性、抓牢本底优势、控制开发时序等应 对措施,为成渝中小城市高铁站区未来规划与 发展提供了理论依据。

Abstract:
In the construction of Chengdu-Chongqing Twin Cities Economic Circle, the Chengdu Chongqing High Speed Railway, as an important driving force for the integrated development, brings new development opportunities to small and medium-sized cities along the route. At the same time, as the key area of inter-city and intra-city connection, the more complete the construction of high speed railway station area is, the more convenient services can be provided for the flow of talents, which can effectively promote the economic linkage and development of the urban agglomeration. Therefore, the construction of small and medium-sized station areas has put forward higher requirements, which are not only limited to the satisfaction of basic transportation functions, but also conducive to the positive linkage between Chengdu-Chongqing cities, to improve the quality of small and medium-sized cities and the quality of life of the residents, and to explore China’s new urbanization road. However, problems such as unclear positioning, slow development, and lack of vitality are common, which directly affect the role of station engine, thus leading to small and medium-sized cities not being able to continuously link with the central city externally to get spillover dividends, and internally not being able to enhance the radiation range of the station area to support the development of industry and population in the new city. Therefore, relying on multi source spatial and temporal data such as RS historical remote sensing and Baidu API points of interest, the study selects nine station areas along the Chengdu-Chongqing high-speed railroad as the research object, and explores the spatial and temporal evolution characteristics of station area elements and their mutual influences from the three aspects of development mode, development speed and functional positioning. It is found that: small and medium-sized station areas have formed an obvious point-axis radiation development pattern, and the development of the old city-oriented area is faster than that of the old city-backward area; among the factors influencing the development speed, the city scale has no significant influence on it; among the functional positioning, the development of transportation subsidiaries is slow, the company’s industry is not associated with the city characteristics, and other services are not dynamic enough. And based on the point axis radiation pattern and spatial value, the following countermeasures are proposed: 1) Enhance transportation accessibility. On the one hand, from the macro site selection to minimize the small and medium-sized cities separated from the location of the site should be contained and adjacent to the main type; on the other hand, to strengthen the station area road system and the urban arterial road system of a variety of articulation possibilities, to increase the density of the station area side road network, focusing on the development of the city center and the link of the public transport system.2) Grasp the underlying advantages. Concentrate high-tech industries and tertiary industries that are related to characteristic industries and require high transportation accessibility in the vicinity of the station, so as to promote the development of station areas in small and medium-sized cities.3) Control the development sequence. According to the ranking of space development value, the first stage gives priority to the development of the space adjacent to the station and the point axis corridor area, which is convenient for displaying the city image and playing a demonstration effect. Completing the necessary supporting facilities, gradually accumulating popularity, increasing the vitality of the station area and its linkage with the city; then taking the area facing the city as the key development object in the second stage, developing industries and their supporting facilities, injecting power for the station area and the city; finally, after the value of the station area has been further enhanced, the development of the area backing to the city will be carried out to solve the residential demand of the overflow commuters from the center city on the one hand, and on the other hand, continue to improve the facilities and supporting facilities to systematically construct the ecological circle of the high-speed rail. On the other hand, continue to improve the facilities, and systematically build a high-speed rail ecosystem. At the key stage of innovative development, the study summarizes the spatial-temporal evolution law embodied in the role of various elements at the present stage, which provides a theoretical basis for the future planning and development of high-speed railway station areas in Chengdu-Chongqing small and medium-sized cities. At the same time, with the deepening of regional integration development, the linkage role of each station area to the urban agglomeration will become more and more prominent, and the study will continue to follow up and superimpose and correlate with the data in different fields, such as cell phone signaling, Baidu heat, etc., so as to deconstruct the relationship of elemental flow between station areas of small and medium-sized cities from the perspective of the city agglomeration’s linkage development, to push forward the coordinated development of the areas along the route, and to better realize the synergistic construction of Chengdu-Chongqing area.
