摘要:

提升区域可达性能显著促进地区经济发展,可达性分析成为评估交通网络建设效益及制定决策的重要内容。针对传统可达性分析模型的不足,本文采用模拟精度更高的矢量—栅格集成法,以厦深高铁为例,分析高铁开通前后广东省东部区域可达性变化程度和空间分布,探讨高铁对研究区域不同尺度发展的影响。结果显示:厦深高铁显著提升区域交通可达性,但不同站点间提升程度有所差异;高铁对区域可达性影响具有显著的隧道效应,可达性变化较高的空间分布方向与厦深高铁一致;厦深高铁对区域交通可达性的公平性和区域产业发展都将产生一定影响,高铁对中小站点地区发展的刺激作用将是长期的过程。

Abstract:

With the rapid development of high-speed rail (HSR) in the world, accessibility by high-speed railway has become a important topic in accessibility research. The implementation of the Xiamen-Shenzhen HSR in southern-east China offers a new option for travelers, but also influences or generates the redistribution of demographic and economic activities. This study applies an integrated method to explore the regional spatiotemporal accessibility on a Geographical Information System (GIS) platform. This method makes full use of the advantages of network analysis and cost-weighted raster analysis, and removes the limitations existed in current accessibility analysis. The research area covers seven cities in eastern Guangdong Province due to the limited availability of data. Results are as follows: (1) The Xiamen-Shenzhen HSR condenses spatial and temporal distances and improves the regional accessibility significantly. Regional average accessibility time was 1.652 hours before the operation of the rail, and this accessibility time is improved to 1.418 hour after the operation, with an increase of 14.16%. (2) The spatial structure of the accessibility change presents an "island" or "banding" shape. At the station level, the rail creates concentric rings of accessibility change, while at the regional level accessibility change are along the HSR corridor. (3) The HSR substantially modifies the map of regional accessibility by reducing travel time and brings the peripheral areas closer to the central city (Shenzhen). However, it may also produce an increase of the core-periphery imbalances. The HSR also has a potential influence on the industrial upgrading and collaboration with a shrinking distance. Finally, the stations in the core cities are the chief beneficiaries of the new spatial order. The stimulation to development around stations in small or medium cities will be a long-term process.
