城市交通网络形态对工业用地转型的影响——以武汉市为例

Impact of Urban Transportation Network Forms on Transformation of Industrial Land:Taking Wuhan City as An Example

城市交通网络的发展通过改变各类城市用地可达性,推动周边土地利用结构重新“洗牌”,成为城市更新的主要驱动力之一。以重要工业城市——武汉市为例,运用核密度分析、地理加权回归、对数衰减函数比较探讨了2014~2019年不同交通道路网络对城市工业用地转型的影响。研究结果表明:(1)各等级交通道路网络沿线“工转居”总量大于“工转商”总量。(2)支路路网对“工转居”、次干道路网对“工转商”显著相关且正向驱动作用明显,并分别呈现出由南至北减弱、由东向西减弱的态势。(3)路网对“工转居”的吸引作用:次干道>主干道>铁路;路网对“工转商”的吸引作用:高速路>次干道>主干道。基于研究成果,对中国城市空间优化、交通网络规划政策制定提供相关建议。

The development of urban transportation network has become one of the main driving forces for urban renewal by changing the accessibility of various urban functional land and promoting the reshuffling of the surrounding land use structure.Taking Wuhan,an important industrial city,as an example,this paper uses kernel density analysis,geographically weighted regression,and logarithmic decay function comparison to discuss the impact of different traffic road networks on the transformation of urban industrial land from 2014 to 2019.Research results:(1)The total amount of“industrial land to residential land”along the traffic road network of all levels is greater than the total amount of“industrial land to commercial land”.(2)The branch road network has a significant correlation and positive driving effect on“industrial land to residential land”,and secondary road network has a significant positive driving effect,and shows a weakening from south to north,and a northwest to northwest road network.The weakening situation in the southeast.(3)In terms of the attraction of the road network to“industrial land to residential land”:secondary roads>main roads>railways;in terms of the road network’s attraction to“industrial land to commercial land”:expressways>secondary roads>main roads.Based on the research results,it provides relevant suggestions for China’s urban space optimization and transportation network planning policy formulation.
