| 摘 要： | “1 h交通圈”的确定对区域经济发展、城市远景规划，甚至居民的生产生活都有着重要影响。然而现有研究几乎都采用欧几里得距离（直线距离）方法定性地、粗略地表示“1 h交通圈”。为弥补这些不足，文章以广州为例，根据城市道路交通网络来划分广州“1 h交通圈”，定量并精确地分析该交通圈。结果表明：1）广州“1 h交通圏”覆盖了珠三角的9个主要城市，其中佛山受益最大；2）广州“1 h交通圈”的主要贡献对象是城际轨道交通和高速公路网；3）由于城市道路并非直线，广州“1 h交通圈”的范围集中在主城区的120 km缓冲区范围内；4）因为广州周边的交通网络发达，其“1 h交通圈”没有显现出很多的岛状区域。此外，广州“1 h交通圈”也对经济发展、政府服务、城市生活和基础设施建设有重要影响。

| Abstract: | One-hour traffic circle has a significant impact on regional economic development, urban planning and daily life of residents. However, almost all existing studies use Euclidean distance method to study the circle. That is a simple way which only can artificially, qualitatively and roughly express the one-hour traffic circle. To overcome those shortcomings, this paper presents the traffic circle of Guangzhou according to the complex road network system, and analyzes the traffic circle quantitatively and accurately. The results show that: 1) The one-hour traffic circle of Guangzhou covers the nine major cities in the Pearl River Delta, in which Foshan benefits the most; 2) The inter-city rail transit and express highway networks contribute the most to the formation of one-hour traffic circle; 3) The one-hour traffic circle of Guangzhou is delimitated in a range of 120 kilometers from the central district of the city since urban roads are not straight; 4) There are not many islands in the traffic circle because of developed transport network. |
