跨城功能联系视角下的都市圈国土空间规划实施监测

Implementation monitoring of territorial and spatial planning in metropolitan areas from the perspective of intercity functional linkages

移动定位大数据可在都市圈的国土空间规划实施监测中发挥重要作用。在流空间理论下,都市圈功能一体化表现为同城化"跨城功能联系"。"居住—工作"和"工作—工作"这两种跨城功能联系是都市圈功能一体化形成的标志,也是都市圈国土空间规划实施监测的关注重点。本文以上海都市圈为例,提出了以移动定位大数据支持都市圈功能一体化规划实施监测的方法。首先,移动定位大数据可以从城际出行有效地量化测度跨城功能联系。其次,移动定位大数据在都市圈规划实施监测中有3个适用领域:(1)使用跨城功能联系界定都市圈紧密联系范围;(2)监测都市圈产业分工带来的人力资源要素流动;(3)监测都市圈的交通基础设施建设绩效。最后,研究认为以功能一体化为目标,都市圈国土空间规划需要以支持跨城功能联系的空间体系为主导,跨城功能联系为主的"流动空间体系"应作为规划编制、实施、监测、评估的重要内容之一。

Mobile positioning big data can play an important role in the implementation monitoring of territorial and spatial planning. Based on the theory of "space of flows", the functional integration of metropolitan area is represented by intercity functional linkages in the area. The two intercity functional linkages of living-working and working-working are the signs of the functional integration of a metropolitan area. This study took Shanghai metropolitan area as an example, and proposed a set of methods for monitoring the functional integration of the metropolitan area with mobile positioning big data. First, mobile positioning big data can effectively quantify intercity functional linkages from intercity travels. Second, there are three application areas of mobile positioning big data in the implementation monitoring of territorial and spatial planning. The first is to delineate the scope of close connection in the metropolitan area using intercity functional linkages. The second is to describe and quantify the functional flow of resources brought by the industrial division in the metropolitan area. The third is to monitor the performance of transportation infrastructure in the metropolitan area. Finally, with functional integration as the goal, the spatial planning of the metropolitan area needs to be guided by a spatial system that supports intercity functional linkages. The system of "flow space" with intercity functional linkages should be one of the important contents of planning, implementation, monitoring, and evaluation.
