交通基础设施对城市规模的影响研究

The Influence of Transport Infrastructure on Urban Size

交通基础设施是影响城市规模的重要因素之一.在特定的城市发展阶段,一定的交通基础设施条件下对应着其合理的城市规模.本文通过研究交通基础设施内在组成与城市发展的关系,将交通基础设施的布局和规模、节点匹配性及可达性等指标量化,结合经济发展水平对城市规模的影响,根据生产函数理念建立交通基础设施与城市规模之间的模型,并对模型相关参数进行估计.最后,以沭阳城区为例,探索在现状交通基础设施下合理的城市规模,并与现状城市规模进行对比,从而为城市发展和交通基础设施建设提供参考依据.

Transport infrastructure is one of the important influences on urban size. In certain stage of urban involution, status of transport infrastructure always indicates the size of urban area. This paper will do research into the relationship between transport infrastructure and urban involution; quantify indicators such as layout and scale of transport infrastructure, node compatibility and accessibility. Then based on the consideration of economic development towards urban size, the model about relationship between transport infrastructure and urban size is structured, and part of parameters is evaluated. Finally, it takes Shuyang as an example, researches the reasonable urban size under the established scale of transport infrastructure, and compares with its current size.
