Among different types of land use, public open space (POS) is noted as one of the most important assets for a city and local community, which benefits people in terms of their social, physical, and psychological well-being. However, the existing literature has revealed the uneven distribution of POS across different social contexts, which has failed to serve potential users equitably. While there is a significant need for research on the integration of the physical environment and the right to POS, previous studies have failed to show how to best merge these two components to promote equitable use of POS. Focusing on spatial justice as the theoretical basis for planning and assessment of POS, this paper aims to propose a framework for the evaluation of spatial justice performance in POS. We review key theories of spatial justice, and critically evaluate the insights they share when applied to urban POS planning. We examine the issues related to spatial justice of POS from three aspects namely: physical justice; urbanization of social justice; and right to the city, in order to identify the key variables of POS spatial justice. These examinations are supported by the analysed results of opinions from experts collected through both interviews and questionnaires. A conceptual framework for POS spatial justice evaluation is thus developed, which includes five constructs: Access and Management, Sociability and Diversity, Demand and Provision, Social Stratum and Information, and Social Inclusion. The relational interactions among these constructs provide an in-depth understanding and guidance for future work on POS planning, which contribute to bridging the knowledge gap on the subject.

在不同类型的土地使用中，公共开放空间（POS）被认为是城市和地方社区最重要的资产之一，从人们的社会，身体和心理健康角度来看，这对人们有利。但是，现有文献显示，POS在不同社会环境中分布不均，无法公平地为潜在用户提供服务。尽管迫切需要对物理环境和POS权的整合进行研究，但先前的研究未能表明如何最好地合并这两个组成部分以促进POS的公平使用。本文以空间正​​义为POS计划与评估的理论基础，着重提出了一个评价POS空间正义绩效的框架。我们回顾了空间正义的关键理论，并严格评估他们在应用于城市POS规划中分享的见解。我们从以下三个方面来研究与POS的空间正义有关的问题：社会公正的城市化；和城市权利，以识别POS空间正义的关键变量。通过访谈和问卷调查收集的专家意见分析结果为这些检查提供了支持。因此，开发了一个用于POS空间正义评估的概念框架，该框架包括五个结构：访问和管理，社交性和多样性，需求和供给，社会阶层和信息以及社会包容性。这些构造之间的关系互动为POS规划的未来工作提供了深入的理解和指导，
