Effective management of cities using ecosystem services from green infrastructure (GI) requires explicit consideration of the linkages between provision of services and ecosystem service demands (i.e., governance priorities). Identification of stakeholder knowledge and objectives in GI decision-making contexts with respect to ecosystem services may improve urban planning; yet this information is rarely explicit in local contexts and cases. We address this gap by surveying environmental stakeholders and practitioners to investigate how perceptions of ecosystem services influence GI practice in Tucson, AZ. Results indicate that the semi-arid environment and urban design led to prioritizations that focus on water sustainability and urban heat mitigation. We found strong agreement in environmental perceptions between different management sectors. We observed matches (as well as mismatches) between the ecosystem service priorities and important environmental issues. Ecosystem services prioritization revealed a unique classification of ecosystem services that reflects stakeholder priorities. Our findings suggest the study of ecosystem services supply and demand can inform local urban management. These findings from a semi-arid city further suggest that understanding stakeholder knowledge, perceptions, and priorities should be important for cities in other regions where GI is being implemented as an environmental solution to provide ecosystem services.
利用绿色基础设施（GI）的生态系统服务对城市进行有效管理，需要明确考虑服务提供与生态系统服务需求（即治理重点）之间的联系。在GI决策背景下，确定利益相关者关于生态系统服务的知识和目标，可能会改善城市规划；然而，在当地背景和案例中，这些信息很少是明确的。我们通过对环境利益相关者和从业者进行调查来填补这一空白，以研究生态系统服务认知如何影响亚利桑那州图森市的GI实践。结果表明，半干旱环境和城市设计导致了侧重于水资源可持续性和城市热缓解的优先事项。我们发现不同管理部门在环境认知上有很强的一致性。我们观察到生态系统服务优先事项与重要环境问题之间的匹配（以及不匹配）情况。生态系统服务优先排序揭示了一种独特的生态系统服务分类，反映了利益相关者的优先事项。我们的研究结果表明，对生态系统服务供需的研究可以为地方城市管理提供信息。来自半干旱城市的这些发现进一步表明，对于其他正在实施GI作为提供生态系统服务的环境解决方案的地区的城市来说，了解利益相关者的知识、认知和优先事项应该很重要。
