Pocket park groups address high-density areas’ recreation deficits by integrating dispersed micro-parks into coordinated units. These groups enhance equity and personalize services through functional division among member parks. Spatial structures optimize connectivity via slow-traffic links. Performance is quantified by visitor volume, diversity indices, and demand responsiveness. Effective collaboration—whether center-based or decentralized—leverages synergistic effects, where structural cohesion and tailored service division boost collective efficiency beyond individual capacity. This approach transforms fragmented green spaces into responsive recreational systems.
