Abstract

The construction and development of the expressway network has far-reaching significance for the economic growth of Guizhou Province. In this paper, ArcGIS was used to calculate the nodal accessibility, daily accessibility and regional average accessibility of the expressway network in Guizhou Province, and the evolution of the spatial pattern of accessibility under the influence of expressways in Guizhou Province from 2012 to 2019 was analyzed through three different dimensions of accessibility indicators. The results show that with the continuous construction of expressways, the accessibility of the whole province continues to improve. Guiyang, as the provincial capital city, improved the accessibility of expressways the most during the last 7 years. However, due to the inequality of resources, there are still spatial differences in traffic capacity between cities and cities. Among them, Tongren and Xingyi have a small increase in the accessibility of expressways from 2012 to 2019, and the traffic conditions of Tongren and Xingyi are in the inferior position of the whole province.

贵州省高速公路发展对城市可达性的影响研究

高速公路网的建设与发展对贵州省的经济增长具有深远的意义。本文利用ArcGIS计算贵州省高速公路网络的节点可达性、日可达性和区域平均可达性，通过3个不同维度的可达性指标，分析2012 - 2019年贵州省高速公路影响下的可达性空间格局演变。结果表明，随着高速公路的不断建设，全省可达性不断提高。贵阳作为省会城市，近7年高速公路可达性改善幅度最大。然而，由于资源的不平等，城市间的通行能力仍然存在空间差异。其中，铜仁、兴义两市2012 - 2019年高速公路通达性均有小幅提升，交通状况在全省处于劣势地位。
