Abstract:Against the backdrop of accelerating urbanization, diminishing green spaces, and growing concerns over children's physical and mental well-being, rooftop gardens have garnered widespread attention as a key strategy to address the shortage of green space in highdensity cities. However, existing studies primarily focus on their ecological benefits and design standards, with limited exploration from a child-centered perspective. In this context, this study selects four international child-friendly rooftop gardens as research subjects to explore the inherent child-friendly attributes and design practices of these spaces, ultimately developing a set of design guidelines. The results indicate that the core elements of child-friendly rooftop gardens include integrating five major landscape features, ensuring the safe use of the garden by children, enhancing community involvement of children and their families, incorporating cultural and artistic education, and emphasizing adaptive design. Based on these findings, the study proposes recommendations and strategies for integrating child-friendly elements into the design and planning process.
