"伞式共治":城市基层河流治理的河长制实践OACHSSCD

As ecological civilization has been elevated to a national strategic goal,urban grassroots river governance faces the dual challenges of systemic transformation and capacity enhancement.This paper summarizes an innovative river governance model:"umbrella-style co-governance",a collaborative mechanism combining government leadership with social participation.Through structural,procedural,and technological coordination,participants form a governance system characterized by collaboration and coordination,flattened information flow,and closed-loop problem resolution,thereby improving response speed,resource allocation efficiency,and public participation.The findings indicate that the"umbrella-style co-governance"can help construct a collaborative governance structure characterized by complementary functions and operational autonomy,significantly enhancing end-level river and lake governance efficiency and implementation capacity.Through institutionalized social embeddedness,"umbrella-style co-governance"model promotes sustained multi-actor participation and strengthens ecological,social,and institutional outcomes.
