摘要
随着城镇化的快速推进,城市交通拥堵现象日趋严重。如何有效缓解城市交通拥堵问题成为城市地理学、城市经济学等多个学科的关注热点。研究城市交通拥堵的空间格局是有效缓解城市交通拥堵问题的基础和重要途径之一。基于高德大数据平台公布的2017年1月1日至2017年12月31日城市交通拥堵延时指数日报数据,从空间分布、空间集聚、空间差异三个层面考察中国100个城市的交通拥堵空间格局,研究发现:交通拥堵水平较低的城市主要分布于东部地区,交通拥堵水平较高的城市主要分布于西部地区的四川盆地和云贵高原;交通拥堵的Moran’s I指数显示中国城市交通拥堵具有典型的空间集聚特征,交通拥堵在西部地区形成H-H集聚,在东部地区形成L-L集聚;从交通拥堵的空间差异特征来看,中国城市交通拥堵的总体差异呈上升趋势,东中西三大地区交通拥堵的区域内差异在波动中呈上升趋势,区域内差异是导致交通拥堵区域差异的主要来源。
With the rapid development of urbanization,urban traffic congestion is becoming increasingly serious,and how to effectively alleviate urban traffic congestion has become a hot topic in many disciplines such as urban geography and urban economics.Studying the spatial pattern of urban traffic congestion is the basis and one of the important ways to effectively alleviate urban traffic congestion.Based on the daily data of urban traffic congestion delay index published by AMAP data platform from January 1,2017 to December 31,2017,this study examines the spatial pattern of traffic congestion in 100 China cities from the three aspects of spatial distribution,spatial agglomeration and spatial difference.It is found that the cities with lower traffic congestion level mainly distribute in the eastern region while those with higher traffic congestion level mainly distribute in Sichuan Basin and Yunnan-Guizhou Plateau in the western region;Moran's I index of traffic congestion shows that China urban traffic congestion has a typical spatial agglomeration characteristic:the traffic congestion forms H-H agglomeration in the western region while it forms L-L agglomeration in the eastern region;viewed from the spatial difference characteristics of traffic congestion,the overall difference of China urban traffic congestion shows an upward trend,and the regional difference of traffic congestion in the three regions of east,west and central China shows an upward trend in fluctuation;and that the regional difference is the main source of regional difference of traffic congestion.
