摘要：Urban ecosystem services are crucial for human well-being and the livability of cities. Acentral challenge for sustaining ecosystem services lies in addressing scale mismatches between ecologicalprocesses on one hand, and social processes of governance on the other. This article synthesizes a set ofcase studies from urban green areas in Stockholm, Sweden—allotment gardens, urban parks, cemeteriesand protected areas—and discusses how governmental agencies and civil society groups engaged in urbangreen area management can be linked through social networks so as to better match spatial scales ofecosystem processes. The article develops a framework that combines ecological scales with social networkstructure, with the latter being taken as the patterns of interaction between actor groups. Based on thisframework, the article (1) assesses current ecosystem governance, and (2) develops a theoreticalunderstanding of how social network structure influences ecosystem governance and how certain actorscan work as agents to promote beneficial network structures. The main results show that the mesoscale ofwhat is conceptualized as city scale green networks (i.e., functionally interconnected local green areas) isnot addressed by any actor in Stockholm, and that the management practices of civil society groups engagedin local ecosystem management play a crucial but neglected role in upholding ecosystem services. Thearticle proposes an alternative network structure and discusses the role of midscale managers (for improvingecological functioning) and scale-crossing brokers (engaged in practices to connect actors across ecologicalscales). Dilemmas, strategies, and practices for establishing this governance system are discussed
