交通网络发展空间格局变化监测研究

Study on monitoring of spatial pattern change of transportation network development

文章以某设区市为例,从网络密度和便捷度两个方面构建交通网络发展空间格局指标体系,综合测度该设区市交通网络发展水平,并利用探索性空间数据分析方法对该设区市交通网络发展空间格局进行研究。研究表明:(1)2020—2021年,该设区市大部分地区交通网络密度无明显变化,只有海州区的标准差略有下降;(2)近两年该设区市交通网络密度逐步增强的区域主要集中在主城区,城市外围地区交通网络密度增强效应不明显;(3)近两年交通网络密度平均值排名前3的区(灌云县、海州区、连云区)与交通网络便捷度平均值排名前3的区(海州区、连云区、东海县)保持了一定的一致性。

This paper takes a city divided into districts as an example,constructs an indicator system of the spatial pattern of transportation network development from the two aspects of network density and convenience,comprehensively measures the development level of the transportation network of the city divided into districts,and studies the spatial pattern of transportation network development of the city divided into districts by using exploratory spatial data analysis methods.The research shows that:(1)From 2020 to 2021,the traffic network density in most areas of the city divided into districts has no obvious change,and only the standard deviation of Haizhou district has slightly decreased;(2)In the past two years,the areas where the traffic network density of the city divided into districts has gradually increased are mainly concentrated in the main urban area,and the effect of increasing the traffic network density in the peripheral areas of the city is not obvious.(3)In the past two years,the top three districts(Guanyun county,Haizhou district and Lianyun district)with the average value of traffic network convenience have maintained certain consistency with the top three districts(Haizhou district,Lianyun district and Donghai county)with the average value of traffic network density.
