Green infrastructure is an increasingly popular urban sustainability strategy, widely promoted for its ability to provide multiple benefits. We examined 120 planning documents from 19 U.S. cities to identify if and how the stated benefits that cities use within their rationales for green infrastructure programs (rationale statements) align with the criteria used to site green infrastructure at the neighborhood scale (siting statements). Our findings suggest that many of the desired benefits stated in the rationales for green infrastructure lack corresponding and specific siting criteria. This was particularly evident for rationale statements concerning social and cultural ecosystem services, seemingly because certain benefits, especially those related to stormwater management, are prioritized over other green infrastructure services. While multiple benefits remain a dominant rationale for green infrastructure in the cities analyzed, including stormwater management, social cohesion, and biodiversity benefits, siting criteria were dominated by stormwater management, available locations, and other logistical considerations. These findings indicate a large-scale misalignment between the multifunctional ideal of urban green infrastructure and the procedures used to implement green infrastructure programs. We conclude with a discussion of how siting criteria and processes can be elaborated to deliver the desired benefits of green infrastructure.

绿色基础设施是一种越来越受欢迎的城市可持续发展战略，因其提供多种效益的能力而得到广泛推广。我们检查了来自美国 19 个城市的 120 份规划文件，以确定城市在其绿色基础设施计划的基本原理（基本原理声明）中使用的既定利益是否以及如何与用于在社区范围内选址绿色基础设施的标准（选址声明）保持一致。我们的研究结果表明，绿色基础设施的基本原理中陈述的许多预期收益缺乏相应的具体选址标准。这对于有关社会和文化生态系统服务的基本原理陈述尤为明显，似乎是因为某些利益，尤其是与雨水管理相关的利益，优先于其他绿色基础设施服务。虽然多重效益仍然是所分析城市绿色基础设施的主要理由，包括雨水管理、社会凝聚力和生物多样性效益，但选址标准主要由雨水管理、可用位置和其他后勤考虑因素决定。这些发现表明，城市绿色基础设施的多功能理想与用于实施绿色基础设施计划的程序之间存在大规模失调。最后，我们讨论了如何制定选​​址标准和流程以实现绿色基础设施的预期收益。和其他后勤方面的考虑。这些发现表明，城市绿色基础设施的多功能理想与用于实施绿色基础设施计划的程序之间存在大规模失调。最后，我们讨论了如何制定选​​址标准和流程以实现绿色基础设施的预期收益。和其他后勤方面的考虑。这些发现表明，城市绿色基础设施的多功能理想与用于实施绿色基础设施计划的程序之间存在大规模失调。最后，我们讨论了如何制定选​​址标准和流程以实现绿色基础设施的预期收益。
