基于自然的解决方案（NBS）是解决城市面临的多重可持续性挑战的一种有前途的创新方法。然而，国家统计局没有被纳入主流城市发展实践。基于德国，匈牙利，荷兰，西班牙，瑞典和英国的定性比较案例研究，这项研究表明，如何障碍，以城市NBS主流化的城市基础设施制度，这提供了一个更好的，上下文敏感的理解，为什么这些障碍持续存在的结构性条件形成。我们确定了形成城市NBS的七个关键障碍的基本结构性条件：有限的合作治理，知识，数据和意识挑战，私营部门参与度低，城市空间竞争，政策制定，实施和执行不足，公共资源不足，以及具有挑战性的公民参与。这项研究还提出了一个城市基础设施制度的理解，复杂的，异构的系统，由不同的功能域，定义了可持续发展创新的空间。重要的是，我们的案例比较表明，国家统计局在规划过程中的主流化的类似障碍是由不同的结构条件在各国造成的。例如，人们认为公民参与有限的原因是西班牙的环境意识较低，匈牙利缺乏支持参与的资源，以及荷兰的邻避主义。我们的研究结果强调了超越“银”式方法解决国家统计局主流化障碍的重要性，走向系统但对背景敏感的反应，针对具体的城市基础设施制度。这种对障碍及其潜在结构条件的系统理解可以帮助学者和实践者确定将NBS作为城市可持续发展创新主流化的有希望的途径。
Nature-based solutions (NBS) are a promising and innovative approach to address multiple sustainability challenges faced by cities. Yet, NBS are not integrated into mainstream urban development practices. Based on a qualitative comparative case study of Germany, Hungary, the Netherlands, Spain, Sweden, and the United Kingdom, this study shows how barriers to mainstreaming urban NBS are shaped by the structural conditions in urban infrastructure regimes, which offers an improved, context-sensitive understanding of why such barriers persist. We identify underlying structural conditions shaping seven key barriers to urban NBS: limited collaborative governance, knowledge, data and awareness challenges, low private sector engagement, competition over urban space, insufficient policy development, implementation and enforcement, insufficient public resources, and challenging citizen engagement. This study also advances an understanding of urban infrastructure regimes as complex, heterogeneous systems, made up of different functional domains that define the space available for sustainability innovations. Importantly, our case comparison reveals that similar barriers to NBS mainstreaming in planning processes are caused by different structural conditions across countries. For example, perceived causes of limited citizen engagement are low environmental awareness in Spain, a lack of resources to support participation in Hungary, and NIMBY-ism in the Netherlands. Our findings stress the importance of moving beyond 'silver bullet'-type approaches to addressing NBS mainstreaming barriers, towards systemic but contextsensitive responses, tailored to specific urban infrastructure regimes. This systematic understanding of barriers and their underlying structural conditions can help both scholars and practitioners identify promising pathways for the mainstreaming of NBS as an urban sustainability innovation.
