摘要
一小时生活圈对区域经济发展、政府政策制定,以及居民的生产生活均有重要的影响。划分一小时生活圈主要用到地铁、国道、省道和县级道路等数据。其中地铁的影响最大,特别是在人口众多的大都市。文中以广州市为例,根据城市交通网络来划分广州市一小时生活圈,定量并精确地分析地铁对广州一小时生活圈的影响。研究结果表明:①2013和2020年广州市一小时生活圏基本上覆盖了广州市的10区2市以及周边的佛山市。②由于主城区基本是在越秀区、海珠区和天河区,2020年广州一小时生活圈中该3个区的面积比均为100%。③2013-2020年期间,黄埔区、番禺区、花都区和增城市是一小时生活圈中增长较快的区域,这些区域也是地铁增长较快的区域。④广州一小时生活圈基本上没有岛状区域,主要因为广州市地铁-公路网络相对比较发达。
One hour living circle has an important impact on regional economic development, government policy makers, and production and living of residents. The data for dividing one hour living circle are mainly from subway, national, provincial and county roads, in which subway is the most important, espe- cially in populous metropolis. In this paper, while one-hour living circle of Guangzhou city was circled out based on its urban traffic network, the impact of metro system on the one-hour living circle was ana- lyzed quantitatively and accurately. The results show that （ 1 ） one-hour living circle of Guangzhou City in 2013 and 2020 cover ten districts of Guangzhou City and Foshan. （2） Since the main city is basically lo- cated in Yuexiu, Haizhu and Tianhe Districts, the area ratio of the three zones in 2020 are 100%. （3） In 2013-2020, the Huangpu, Panyu and Huadu districts are faster-growing regions due to rapid growth of metro. （4） One hour living circle of Guangzhou basically has no island regions mainly because of well- developed Metro-Road network.
