摘要： 通勤圈识别不仅有助于提升城市运行效率和改善通勤出行品质，更能为城市空间规划与资源 配置提供科学依据。提出通勤圈识别的技术方法，基于多源数据和城市轨道交通OD数据，识别出 青岛都市区存在8 个通勤中心；通过多情景模拟后，确定将10%作为通勤率阈值，由此识别青岛都 市区8 个通勤圈范围。总结青岛都市区通勤圈的主要特征：理论上通勤中心的能级越强，其通勤圈 的范围越大，但实际上若相邻通勤中心的能级差异显著时，高能级通勤圈会覆盖部分低能级通勤 圈；通勤走廊对通勤圈范围影响显著，表现为通勤走廊服务能力越强、辐射范围越广，通勤圈范围 越大且沿通勤走廊延伸的特征越明显。最后，提出通勤圈空间优化策略，包括优化通勤中心职住空 间布局、提高通勤圈内部空间使用效率、构建与通勤圈相匹配的骨干交通系统。

Abstract： Identifying commuting zones not only enhances the operational efficiency of cities and improves commuting experiences, but also provides a scientific foundation for urban spatial planning and resource allocation. This paper proposes a technical methodology for commuting zone identification, employing multivariate data and urban rail transit OD datasets to identify eight commuting centers in the Qingdao metropolitan area. Through multi-scenario simulations, a 10% commuting rate threshold is determined to identify the eight commuting zones. The main characteristics of these zones are summarized as follows: in theory, commuting centers with higher capacity are associated with larger commuting zones; however, in practice, when adjacent centers vary significantly in capacity, higher- capacity commuting zones tend to overlap with the spatial extent of lower-capacity ones. Moreover, commuting corridors exert a significant influence on the spatial extent of commuting zones—the stronger the commuting corridor's service capacity and the wider its coverage, the larger the commuting zone and the more prominent extension along the commuting corridor. Finally, the paper proposes spatial optimization strategies for commuting zones, including optimizing the spatial layout of jobs and housing within commuting centers, enhancing space use efficiency within commuting zones, and developing a backbone transportation system aligned with commuting zone structures.
