提供生态系统服务是城市绿化的一个重要理由，而“树木是好的”这句话也很流行。然而，在理解城市树木如何促进可持续发展的同时，还必须考虑到它们的危害。在这篇前瞻性文章中，我们讨论了最近关于城市树木生态系统危害的研究，包括基础设施冲突、健康和安全影响、美学问题、环境有害后果，以及与生态干扰和风险管理相关的管理成本。我们还讨论了关于物种选择和当地保护问题的权衡，以及人类感知在解释生态系统服务和危害中的核心作用，特别是“每个人都喜欢树木”的不加批判的断言。城市林业决策未能考虑到危害，可能会对社区产生意想不到的负面影响。在城市林业的生命周期评估、利益相关者决策、投资回报、服务和危害框架等方面需要进一步的研究。
The provision of ecosystem services is a prominent rationale for urban greening, and there is a prevailing mantra that ‘trees are good’. However, understanding how urban trees contribute to sustainability must also consider disservices. In this perspective article, we discuss recent research on ecosystem disservices of urban trees, including infrastructure conflicts, health and safety impacts, aesthetic issues, and environmentally detrimental consequences, as well as management costs related to ecological disturbances and risk management. We also discuss tradeoffs regarding species selection and local conservation concerns, as well as the central role of human perception in the interpretation of ecosystem services and disservices, particularly the uncritical assertion that ‘everybody loves trees’. Urban forestry decision-making that fails to account for disservices can have unintended negative consequences for communities. Further research is needed regarding life cycle assessments, stakeholder decision-making, return-on-investment, and framings of services and disservices in urban forestry.
