Despite the prevalence of polycentricity as a normative strategy in planning documents, a lengthy and inconclusive debate regarding its definition in academic research persists. The aim of this article is to eliminate the conceptual confusion surrounding functional polycentricity from a geographical perspective. By classifying different approaches to polycentricity, we outline the properties that characterize all forms of functional polycentricity. Accordingly, we redefine functional polycentricity and propose a corresponding framework with which to measure it. The commuting and leisure functional polycentricity of Atlanta is used as an example to illustrate the application of this framework.

从地理角度定义功能性多中心性

尽管在规划文件中普遍存在多中心性作为规范性策略的问题，但在学术研究中，关于多中心性的定义仍存在冗长而不确定的争论。本文的目的是从地理角度消除围绕功能多中心性的概念混乱。通过对多中心性的不同方法进行分类，我们概述了表征所有形式的功能性多中心性的属性。因此，我们重新定义了功能性多中心性，并提出了一个相应的框架来对其进行度量。以亚特兰大的通勤和休闲功能多中心为例，说明该框架的应用。
