摘要:
［目的］深入掌握国外发达都市区轨道交通演进历程，有利于我国超大、特大城市建构科学的轨道交通线网形态，安排合理的建设时序。首尔都市区与我国超大城市空间结构和轨道交通发展基础有更强的类似性，更值得深入研究。［方法］采用案例比较与演绎的研究方法，总结了首尔都市区人口与土地空间演进历程特征，分别研究了地铁、都市快轨、准高速通勤快线等的供给特征。［结果及结论］首尔都市区轨道供给存在普遍性规律，也有其独特性。我国超大城市都市快轨供给不具备首尔都市区的历史条件，且受空间形态影响，因此其里程占比应远小于首尔都市区的；站间距指标对实现都市快轨预定职能有重要的保障意义。

［Objective］ The comprehensive understanding of rail transit evolution in developed metropolitan areas abroad is beneficial for the scientific construction of rail transit network and the rational scheduling of construction phases in China′s mega and super cities. Seoul Metropolitan Area shares stronger similarities with mega cities in China in terms of spatial structure and rail transit development foundation, making it a valuable case for in-depth study. ［Method］ Using case comparison and deductive research methods, the characteristics of population and land space evolution in Seoul metropolitan area are summarized, and the supply characteristics of different rail modes, including metro, urban rapid transit, and quasi high-speed commuter express are further examined. ［Result & Conclusion］ The rail transit supply in Seoul metropolitan area follows certain universal patterns, but also exhibits its unique characteristics. Unlike Seoul, urban rapid transit supply in China′s mega cities does not bear the historical conditions that shaped Seoul, and they are further constrained by spatial structure, thus the proportion of its mileage is significantly lower than that in Seoul metropolitan area. The station spacing metric is crucial in ensuring that urban rapid transit fulfills its intended function.
