Abstract The idea of nature having multiple benefits for urban management and planning is gaining prominence alongside the rise of climate change awareness. It is expressed through concepts such as nature-based solutions (NbS), ecosystem-based adaptation (EbA), and blue-green infrastructure (BGI). Despite their popularity in the international arena, relatively little is known about how these concepts are used and interpreted at the local level, which has implications for policy formulation and actions. This paper examined both direct and indirect references to these concepts, as well as the reasons for their potential omission. By analysing policy documents and interviews with practitioners and activists from four Polish cities (Gdansk, Krakow, Warsaw, Wroclaw), it discussed the uneven and ambivalent uptake of concepts in the urban green and blue space (UGBS) governance. While the reluctance to use new terminology was often explained by accessibility and efficiency concerns, it also revealed some conceptual confusion. The contribution of this study is twofold: 1) providing a more nuanced understanding of the conceptual ambiguity surrounding the NbS, EbA and BGI concepts and the gap between international policy rhetorics and local interpretation; 2) expanding the geography of research on urban climate adaptation and urban green spaces which tends to overlook the countries of Central and Eastern Europe.

城市绿化新概念的采用：来自波兰的见解

摘要 随着气候变化意识的提高，自然对城市管理和规划具有多重好处的想法越来越突出。它通过基于自然的解决方案 (NbS)、基于生态系统的适应 (EbA) 和蓝绿基础设施 (BGI) 等概念来表达。尽管它们在国际舞台上很受欢迎，但对这些概念如何在地方层面使用和解释的了解相对较少，这对政策制定和行动有影响。本文研究了对这些概念的直接和间接引用，以及它们可能被遗漏的原因。通过分析政策文件以及对来自四个波兰城市（格但斯克、克拉科夫、华沙、弗罗茨瓦夫）的从业者和活动家的采访，它讨论了城市绿色和蓝色空间 (UGBS) 治理中概念的不均衡和矛盾的吸收。虽然不愿意使用新术语通常是由可访问性和效率问题来解释的，但它也揭示了一些概念上的混乱。本研究的贡献有两个方面：1) 对围绕 NbS、EbA 和 BGI 概念的概念模糊以及国际政策修辞与当地解释之间的差距提供了更细致入微的理解；2) 扩大城市气候适应和城市绿地研究的地理范围，这些研究往往忽略中欧和东欧国家。本研究的贡献有两个方面：1) 对围绕 NbS、EbA 和 BGI 概念的概念模糊以及国际政策修辞与当地解释之间的差距提供了更细致入微的理解；2) 扩大城市气候适应和城市绿地研究的地理范围，这些研究往往忽略中欧和东欧国家。本研究的贡献有两个方面：1) 对围绕 NbS、EbA 和 BGI 概念的概念模糊以及国际政策修辞与当地解释之间的差距提供了更细致入微的理解；2) 扩大城市气候适应和城市绿地研究的地理范围，这些研究往往忽略中欧和东欧国家。
