摘要:

对丝绸之路经济带交通网络及城市空间联系进行分析是实施丝绸之路经济带战略和推进沿线区域合作共赢的基础工作。本文基于GIS空间分析技术,研究了丝绸之路经济带栅格可达性空间格局,并依托陆路交通网络进行了城市空间联系状态模拟。结果显示:丝绸之路经济带内城市可达性空间分布呈现出集聚分布的特点,具有明显的“走廊”空间特征。城市节点平均可达性时间为16.25 h,可达性在2 h以内的区域仅占全区总面积的10.60%,可达性最差的区域大都为荒漠地区,最差可达性高达171 h;西安作为门户城市,承担了中国西北五省与丝绸之路经济带有关国家、地区和城市之间的联系。中亚国家内部及其与外部国家城市之间的空间联系较为薄弱;丝绸之路经济带正在发育形成4条轴线,在未来丝绸之路经济带战略推进过程中,应实施“点—轴”带动,协同推进重点发展走廊和中心城市培育工作。

Abstract:

Analyzing accessibility and urban spatial connection of the Silk Road Economic Belt is the basis for implementing the strategy of the Silk Road Economic Belt and facilitating cooperation and achieving mutual benefits of the region along the economic belt. Based on GIS spatial analysis technology, the spatial pattern of raster grid accessibility for the Silk Road Economic Belt is studied and the states of urban spatial relation are simulated using land transportation network in this research. The result shows that the spatial distribution of urban accessibility in the Silk Road Economic Belt presents clear spatial characteristics of aggregated distribution along the main corridors. Average accessibility of urban nodes as measured by travel time is 16.25 hours, and the areas accessible within 2 hours occupies 10.6% of the total area. Most of the areas with the lowest accessibility are found in the margins of the deserts, with the worst accessibility of 171 hours. Xi'an as the gateway city connects the five provinces of Northwest China and other countries, regions, and cities of the Silk Road Economic Belt. The spatial connections of Central Asian countries within e national boundaries and with cities outside are relatively weak. The Silk Road Economic Belt is forming four main axes. In the future strategic development of the Silk Road Economic Belt, it should consider to implement a "point-axis" growth structure to drive the development of corridors and central cities (dense urban area).
