ABSTRACT Global enthusiasm for nature in cities is at high point. Australia is no exception, where there is a great deal of policy momentum and research interest in urban greening. The challenges presented by increasing urban heat associated with climate change, greater awareness of the potential social, physical and psychological benefits of exposure to ecologies for people, and recognition of cities as vital habitats for more-than-humans are central tenants of urban greening enthusiasm. Yet, there is a need for a more critical lens on urban greening in Australia. One that interrogates the purported normative, apolitical and instrumental benefits of greening, to position greening within a trajectory of the power relations, settler-colonialism, socio-ecological processes and capital flows that constitute the urban. This editorial introducing the special issue on urban greening politics explores how different conceptions of urban natures – green space, urban forestry and green infrastructure – have been put to work, before outlining the potential of ‘urban greening’ as the terminology for a more politically sensitive and process-orientated framing. The editorial concludes with a summary of the contributions to the special issue.

城市绿化政治：导论

摘要 全球对城市自然的热情正处于高潮。澳大利亚也不例外，那里对城市绿化有很大的政策动力和研究兴趣。与气候变化相关的城市热量增加带来的挑战、人们对生态环境对人们的潜在社会、生理和心理益处的认识以及将城市视为超越人类的重要栖息地所带来的挑战是城市绿化热情的核心租户. 然而，需要对澳大利亚的城市绿化采取更严格的视角。一种质疑所谓的绿化的规范性、非政治性和工具性好处，将绿化置于构成城市的权力关系、定居者-殖民主义、社会-生态过程和资本流动的轨迹中。这篇介绍城市绿化政治特刊的社论探讨了城市自然的不同概念——绿地、城市林业和绿色基础设施——是如何被运用的，然后概述了“城市绿化”作为更具政治敏感性的术语的潜力和面向过程的框架。社论最后总结了对特刊的贡献。
